Power Acoustik = crap . Nothing more to say. They blow like no tomorrow if you put clean power into their power ratings and they still sound like garbage. Really, take like12 MOFOS and you might have a decent SPL score, but after you do that test tone you'll probably see smoke. I agree with DYohn, in which i can never recommend them.

well then... What would be sum good subs and a nice amp to push them... for like... 500 bucks?

you see... right now i have 2 12" Xplods... running off of a US Acoustic amp... like 300 rms each sub, and the amp puts out like 300 rms to 2 channels... i am looking for an upgrade =)

who wouldnt when ur car sounded this sh*tty... ? lol

You can pick up a couple of Infinity Kappa 12's for less than $250 and keep your US Acoustics amp.

Support the12volt.com

Check out Adire, MB Quart, Diamond, Memphis, Image Dynamics, Infinity, MTX, etc. There are a lot of good subwoofers out there for not much money. Keep that amp.

Also, remember that severe clipping can make ANY subs sound like ass. Make sure your gains are set properly before you go buying anything new.

You could go with 2 Adive shivas..$125 each..plus shipping..you'd still have atleast $200 left over for an amp and correct me if i'm wrong but the Shivas dont need much power..

ok i got a bunch of options... why stay with the crappy us acoustic amp? ... its the Usb600D amp... Here let me find a link... Click here ... it doesnt put out much... ? ...

no clipping... i just want deeper bass... louder... so not only can you hear it deeeep in the car... but you can hear it a few houses away... =)

or... possibly... i could get 2 of one of the subs listed above... and buy another Us acoustic amp... wich was like 150... if i can remember correctly... then... i could put a seperate amp to each sub... then it would actually be powering the sub to what it is capable of... correct?

US Acoustics amps are very good quality for the money. Not crappy at all.

hmmm... i never knew that... well... if i had 2 kappas... which ones would i get? ... and would my amp be able to actually push 2 subs to their potential? ...

or should i get another amp? the same one... a single amp to a sub...

Thats a good amp, but if you want bass that lets people no your comin a block away (and who doesnt posted_image

) you might want to consider upgrading. You can get a JBL 600.1 on sounddomain for $160, and you can probably find a similar Hifonics amp for between 150 and 200. For subs I would try Memphis, Alpine Type-R, Orion, Adire Shiva, MTX, etc.

oops... sorry... lol

how about someone recommend a single sub, single amp... lol... i have too many options... and will never be able to choose... sumone mention 2 single subs, and a single amp that will make me be heard... lol

remember... i have 500 bucks to spend... so ya...

For a limited budget of $500, i really can't see you doing better than 2 12'' Adire Audio Shiva's (Yes i know shiva's are the 12's) and you can get a really nice amp for them for 250 that will give you the power you need. Another suggestion is Rockford Fosgates HX2's, you can get them cheap on ebay, and they sound really good too for the money. The Shiva is the best budget speaker ever made in my opinion, great SPL while maintaining fantastic SQ. Make a good enclosure for them and they will crank. Check them out at www.adireaudio.com

Let us know what you think.

Keep your US Acoustics amp. It puts out a clean 375 watts into 2 ohms. Spend yur money on a 12" Adire Brahma (can be had for around $350) and a custom enclosure for it built by a local shop (~$150). The Brahma will sound pretty sweet with 375 watts, and then after you save your money for a few months go get a more powerful amp in the 1000 watt range.

-------------
Support the12volt.com

You can find the Brahma at www.adireaudio.com and i agree with DYohn, in a custom enclosure you better believe that you will be heard. They don't require that 1600 RMS to be brought to full excursion as it says in the site, you can use significantly less power. That 375 is plenty if you build the right enclosure.

"I don't play games. I play Nakamichi and that for real yo" - Probably some japanese kid said this in the early 80's trying to sell stereo out of his trunk lol.

i already have a box... and i really dont feel like buying another one... i have a dual 12" box... its like ported through a fat slit in the middle... but ya... i cant seem to find any sites selling adire shivas... i search google and it comes up with nuthin but reviews... ? help... link me to 2 12's and a amp to push them... so the biatch bumps...

You can buy it right off the site here https://www.adireaudio.com/Merchant2/merchant.mvc?Screen=CTGY&Store_Code=AA&Category_Code=2000 and as for an amp, they really don't require much power. There is a video on their site of a shiva pumping at 60 W and it was moving. As for what you should give to of them, i would ask Steve Kephart, who is the real deal from Adire. I myself have been curious about their power ratings, as they follow suit with the Brahma of needing significantly less power to push them to full output.

Here are the statistics from the site:

PARAM	VALUE	PARAM	VALUE
Re	2.9 ohms	Le	2.12 mH
Qms	6.5	Mms	125 grams
Qes	0.40	Cms	0.47 mm/N
Qts	0.38	Rms	2.54 N*s/m
Fs	21 Hz	Sd	481 cm^2
Vas	151 liters	BL	11.3
Xmax	16.6 mm one way	EBP	51
SPL	87.3 dB @ 1W/1m	No	0.37%
Pmax	375W per voice coil; 650W total to the driver NOTE: Power rating is thermal only! It is NOT a power requirement; typically you get full output with significantly less power than the rating.	PRICE	$125.00

You can't just buy some subs and put them on any box (specially a ported box).

The box has to match the sub.

Not all subs are the same and they all require different enclosures. So what ever you end up buying you will either have to get a new box to go with your subs or find subs that will match your box and then have the box tuned to the specs of the subs.

Here start with this : https://www.the12volt.com/caraudio/boxes.asp

Very true, you will have to have your boxed tuned to different woofers. You can't throw a 15" Pyle into a box built for a 15'' Juggernaut and expect it to sound right...

A 12" Brahma in a good ported enclosure will give you plenty of bass and if u wanted to upgrade to a more powerful amplifier later...you could look into the JBL BP600.1 off www.sounddomain.com ..It's well under $200 and quite underrated. The two tricks to that amp is RCA splitters and an F-Mod, because it lacks a SSF..just an idea

Also..i know someone who's running a 15" Brahma off the 600.1 and hits 134db all day long

my box is... 30 inches wide... 15 inches deep... and 14 inches tall... what would the volume be? ... and would that volume work with 2 adire shivas? ...

you're box is 3.65^ft..I highly doubt it would work well with the 2 shivas..spend the money and have a box professionally made to it's specs..whether you go ported or sealed is your choice..personall id go ported..that's just my opinion

well... what is recommended for shiva 12's ported? how many cubic feet?

here, better yet what 2 subs would be the best for a 3.65 ^ft box? it is ported through a slit in the middle...

ohh its slot ported..well you'd have to subtract the port displacement and sub displacement to get your final numbers...the figure i gave you was w/o displacement..trust me on this one..its better to get one built for the subs you choose ..you could build it yourself if you want.

"I don't play games. I play Nakamichi and that for real yo" - Probably some japanese kid said this in the early 80's trying to sell stereo out of his trunk lol.

u see... i have a box and dont feel like spending more money on one... i can unport it, just seal the front port.... or make it a bit smaller, etc... just what are 2 12"s that would work well in a 3.65^ft box... and what is a nice amp to push those 2 subs... all under 500 bucks...

if thats the way you want to go you are going to have to give us your port dimensions also for us to give you a solid reccommendation

uhhh... well... it's a slit port... in the middle of the box... goes from top to bottom... it is 3 inches wide... and you kno how those kinda boxes go, they go from the front of the box, around the corner to the back, and around and out the front... through the 2 tunnel deals... they are 3 inches each... so like... the box not including any of the port crap is about 25 inches... across... so 12.5 inches for each sub, across and 15 inches deep... if i were to knock out the first wall of the port, it would make it... about 15" across, each... so ya... if that made any sense to you, or anyone... lol

when you say what subs would be the best...what do you mean...do you want subs that are loud and dont sound bad or do you want subs that sound really damn good but arent really that loud for the money

i want something that will be heard... loud is better... but i mean not really crappy quality... just the loudest quality for the money... 500 dollars for 2 subs and an amp... and is made for sumthing close to my box...

what kind of sonys do you have now

no idea... lol... uhh let me go look on the box... they are 10" XS-L1037's ... dont know if u will be able to find them online... i got them a Wal-Mart lol...

https://cgi.ebay.com/dll?ViewItem&category=3291&item=5734287337&tc=photo

but i want something better and that hits harder than these... they suck ...

honestly your box size sounds just about right for two sony p5s...a little big but close enough...i have heard them hit really hard in the right box before...if you try that route though...make sure to get the red ones and not the grey ones that wall mart carries...also...power acoustik makes a decent amp for about $200 or there is always the p miller amp by bazooka for a little more...you can probably find a lot better deals on amps on the internet...i get a lot of people in at work that ask for just about what you are asking...so don't let anybody talk you out of any of these options...i'll bet you would be happy with them

personally i think sony sucks... and i dont kno crap about car audio... i think everyone else will agree that sony, sucks... i dont feel like getting any more xplods... i am staying away from those...

i am looking for sum higher quality...

a sub that costs 50 bucks, i feel wont be too good... for sum odd reason?

just a suggestion...im not a big sony guy either...but don't categorize one brand because of one specific model...no one who knows anything and is actually open minded would say that sony sucks...that would be like saying that escalades suck because they are made by the same company that makes the cavalier or the metro...its called branding...but hey...if staying away from sony makes you happy then good...taking your port displacement out of the equation...if i understood your numbers right...sounds like you box is a little larger than 2.75 cube...keeping that in mind start surfing around on the web and see what catches your eye

i dont know what to search for... and i dont know quality when i see it... concidering i cant hear it... that is why i come here for people to recommend a certain sub , amp, etc... because i dont know much... i want sumone to link me to 2 nice 12's that fit my box dimensions... and an amp to push them... under 500 bucks...

i just did...and you didn't like my possible solution because you branded sony...anything that you hear of about quality on any forum will be opinion based and thus means nothing to you...to most of the people on here quality means something entirely different than it does to you...not a personal attack or anything...but it doesn't sound like sound like you are concerned with sq...sounds more like spl...and anyways...a large portion of how good something sounds lies in the installation...in your case how well the box matches the subs...in any case...if you want higher quality...get a better head unit...independent sub level controls and low pass crossovers on a deck can do a lot for a system

Honestly, I wouldn't reccomend any Sony Products to anyone looking to up the quality of their system..The pentagon subs that Sony makes will get fairly loud, but one thing that Sony lacks in their products is dependibility. The amps are complete trash IMO for the simple fact that they don't put out any power and are constantly having problems..I would reccomend Audiobahn above Sony in performance and durability. My first system which was stolen was 2 Audiobahn AW125 12" Natural Sound subs run off an Audiobahn A8000T amplifer..I put the subs in a dual pre fab box..much like the one you are using except mine was sealed...they sounded crisp and fairly loud for the most part. Both of those subs can be had for under $100 on ebay and the amp for under $200. I had no problems with the subs and the amplifier never overheated or shut down for any reason. Normally I would not reccomend Audiobahn products either but this is an option with such a tight budget. You could use your left over money and put it into a good head unit.

You can get some Adire Shivas for $125 a piece, and a Hifonics NX750Dfor $200 or aJbl 600.1 for $160. That will come out to between $400 and $450. If those subs fit the box you have, great, if not, sell it and make one yourself.

-------------

i have a bad past in making box's... it pisses me off... i want a sub that will fit my box... what would?

Your being too stubborn and your missing our points here. Not every sub is the same. If your going to get new subs it is most likely that you will need to get a new box. It is well worth the investment and will make the world of difference in your install. Probably the only sub that would fit and work in that box would be the sub you had before. Unless you go woofers like volfenhag, pyle, and all the other junk out there like them.

I agree, If you don't want to spend any money on a new box or attempt to learn how to build one on your own then it's obvious that quality is not that important to you in which case you could buy whatever 12's you wanted and stick them in the box you have. It could cause damage to the subs you pick especially because its ported..but hey..you didn't have to waste the money on a new box right? Not trying to be cruel..just telling you the truth.

you guys are missing the point... I asked you for a sub that would fit my box... and no one has mentioned one yet... and... I also said i would mess around with my box if u find a sub that would fit close to it... i can unport it, etc... now, what sub would be close to the dimentions of my amp... so i dont have to do tooo much messing around with it? ... i can leave it ported, or unported...

and one more thing... people have been recommending Shivas... and ya, they are also recommending amps that put out like 400 rms each channel... well, 800 x 1.... mono's... and , well... they have also said Us Acoustic amps are nice... Mine puts out 375 x 2... and well, 400, 375... pretty close... not that big a difference... so should i try... 2 shivas, with my amp? ... would that bump? and make my box to the recommended deminsions... let me go look at what they recommend, hold up...

Alignment Suggestions:

Sealed:
25.5 liter with a Q of .95 Best suited for a car or a home application where space is critical.
54 liter with a Q of .707 Well suited for home theater movies as well as music applications.
88.5 liter with a Q of .6 for a tight, well defined audiophile bass output.

according to that there is a major lee-way on how big it can be... mine is like 3.65 cubic feet or sumthin like that...

3.65 (cubic feet) = 103.35649 liters
(103.35649 liters) divided by 2 = 51.678245 liters

and it is actually a little more than that if you include the other port wall...

2 shivas are great, and they don't require much power. If your looking for a shiva though, they require a custom box. Your amp does not chose the subs for your box. The specs on your box chose your subs, but it should be the other way around. I'd sell your box at a flea market and get what you can for it and build one on your own. The material is not expensive and it only takes minor knowledge to build one on your own. You really have to consider a new box, because every sub is different, and most likely will not fit or sound good in the box you have already.

"I don't play games. I play Nakamichi and that for real yo" - Probably some japanese kid said this in the early 80's trying to sell stereo out of his trunk lol.

FYI about the USB600D amp...I have one of those too, and it's rated at 200W @ 4 ohms, 300W @ 2 ohms. I run one sub at 200 watts. I get that power fine, but I can't figure out how it can make 300 watts when it comes with one 20 amp fuse. It has better than 90% efficiency, according to specs, but if you figure car voltage of 14 X 20 amps (fuse) X 90% efficiency = 252 watts. How does it make 300, or better yet, 375 watts? How does it do it? I stated the rating on my amp, taken from the owner's manual, last year's model. The USacoustics page linked to on the first page of this thread shows the new rating for this amp: 250W @ 4 and 375W @ 2 Ohms.............but look down the page.....it still has one 20 amp fuse. I can't get the math to work. Maybe someone can tell me what is wrong here.

It's a good amp, a lot of bang for the buck, but I can't see it putting out the power you want for two blocks of bass. Go to the USX1000D.

US Acoustics have always been a little overrated in power. Their fuses never match their output. Then again, there are many amps the other way, underrated like MMATS, US Amps, Cadence, etc. Really, a great budget amp company is JBL. I love them to death, as they put out clean power that is true to its ratings. Thanks to the CEA! That is the true way to find out what their spec's really are. Look out for that if you can!

dude... have you not read a single thing i have posted? I SAID i would unport, make it smaller, etc...

so, now... Would my Us acoustic usb600d amp push the shivas to what they need? or if not, WHAT amp should i buy? that is around 200 bucks...

Bottom line: do what you want. We are trying to help you but you don't seem to want to listen to us. You insist on using your pre-fab enclosure even when we tell you it is not a good idea. You seem to think your amp is no good even after we keep telling you it's fine. Do you read the messages and not understand, or don't you want to listen to good advise? I'm sorry, but this thread has gotten really long for no good reason. So, if you really want help, I suggest you go to your friendly neighborhood car audio shop and ask for help. Either that, or go ahead and do whatever you want.

I said i am going to make my box smaller to a sub that ios requested... and i never said my amp wasnt good enough... i simple asked, right before you posted this, if my amp would be able to push the shiva's at all... listen to me, for a change... and i mentioned i would change my box, like... 3 times now...

YOU CANNOT CHANGE YOUR BOX FOR SHIVAS!!! You must construct a new box, according to specs. They are very custom woofers. ONCE AGAIN ask STEPHEN KEPHART about their true power ratings. He can tell you if your amp is sufficient to supply that power. I agree with DYohn, you are not even listening to us. Your asking advice and once we give it to you you reject it. So what was the point in asking? Read the posts on this rediculously long thread and understand what you need to do.
