Subject: 2 15 or 4 12
Date Posted: June 02, 2009 at 9:10 AM

I have a 93 caprice and I'm looking for 2 15" or 4 12" subs so that i can get that real low bass and i also want it to be loud. I'm not looking to enter it in any competitions or anything like that, i just want to have one of the loudest systems i can get with 2 15" subs. A guy at a local shop told me do go with 4 12" subs if you have any input as to which set up would be louder, can hit the low bass notes, and have the best sq as well would be helpful. im looking to stay under 500.00 for the subs

It's gonna be kinda hard finding a real quality 15" sub under $250ea IMHO. First thing that comes to mind in that price range is a set of Rockford power T115D4's, or a set of Alpine Type-R or even type-X if you can find a deal. Do you already have a amp?

no not yet i wanted to find some speakers first then i would choose a amp. what do you think about these subs < color=#810081>Alphasonik PSW8154 a friend of mine recommened these. i looked at the alpine type r subs i hear good things about them but i dont know if they can be loud and hit that good bass im looking for thats why i really want to 15's. how much do you think some good ones would run?

Trust me Type R's can get plenty loud.  And you do know they make a 15" type R right?

Yeah i know that, i was just trying to find something a little cheaper that can perform just about the same the 15" alphasonik speakers i posted earlier are 1000 watt rms and i can get two for under 350. i dont know to much about alphasonik, if anyone does have any experience with these speakers i would be happy to hear your opinnion. I have another question about the type r's my cousin has the audiopipe ipipe 1600watts 800rms speakers and they sound amazing how would the type r's compare to those?

why not get 1 really nice 15 or 18 and give it a bunch of airspace to do its thing. you have an older caprice so you definitely have the trunk space to get a good sized box in there.

when it comes to sub performance 1) you get what you pay for and 2) good sound takes more than expensive subs. you need to pair them with an equally good box. you can spend all the money you want but if you stick your subs in a mismatched box then your subs can still sound like poo poo. good bass is more about the box than which subs are being used. so whatever you decide to go with just be sure to buy/make a well built box.

I understand that, what ever subs i get i am going to have a box made for them. the reason i am asking about subs is cause you can have two subs with the same size, wattage and ohms but one sub will out perform the other and if they are both in boxes built to specs, is price the only thing that will tell me which speaker is better? I am not an installer i am a diy type of guy. i have installed some systems before but not on any proffesional level like you guys do it on here, just a basic sub amp and head unit install. i basicly want to know if anyone has had any experience with the speakers i mentioned above and if not then your recomendation on speakers you do have experience with, that fall in the price range.

i think thats a good choice of sub and you shouldn't be disappointed. your amp is a good entry level amp, nothing really special about it. is that amp 1 ohm stable?

I though it was but it's not so i think i will pass on that amp. would you recommend running one 2000watt amp or 2 1000watt amps, and if you have any recommendations i would appreciate it.

i would go with 1 amp. it usually will end up cheaper and less of a headache than installing and setting up 2 separate amps. i dont have too much experience with a lot of different amps (i keep my amps until the wheels fall off) but what im running now is an Autotek MM2000.1D, autotek is owned by the same company as hifonics but autotek is definitely top notch equipment IMO. i've had it for more than 3 years now, i run mine at 1 ohm all day and haven't had any problems with it even during competitions.

what are you looking to spend on an amp?

If you want loud, you got room for 4 12's. Either way, budget at LEAST 150$$ for sound deadening . Also, dont enclose the sound in the trunk. If you can, modify the rear dash in some way to allow for sound to escape.

What kind of sound deadening would you suggest? and how many layers im talking bout just for the trunk.

If u want to hit low and have it loud, try Fi car audio subs. I just got a Sundown Audio saz2000d on presale for under $500 with free shipping. Check it out.

The saz2000d is an amp. Not a sub. Sorry if there was confusion.

OH ya, minimum 1 layer, 2 would be nice. The more the merrier. Sometimes it can be beneficial to carefully spray some expanding foam inside cavities throughout the body. A trunk lid is a good place to hit too. Just dont over use it. Simply enough to bridge gaps or fill holes.

Fatmat is only similar to Dynamat and other butyl based mats in that Fatmat has an aluminum backing.

Fatmat is asphalt based.

it still works and i think they changed their formula anyway to be less asphalt based because the last time i used it was to do my friends trunk and it didn't smell like asphalt like it used to. it doesn't peel off either if you apply it the right way.

i always liked the alpine type r's, you can not go wrong with those subs. the price is cheap and you get a lot of bang for your buck. also someone said RE subs were good. you might want to look into no name people. i mean by companys who instead of spending all their money on marketing their product and building up their name brand, they spend it on improving their product and letting word of mouth sell their product. if you havent purchased your amp i would consider the future. i have a feeling that no matter what you get now and no matter how much it hits or how good it sounds to you, you might want more latter on. when i got my first system i got two MTX 5000 12's and a PPI art 600.2 amp. for me that set up sounded great, but after a month or so i wanted more. the thing was the amp was not able to put out what i wanted, so i had to wait a while before i could purchase a better system. the amp is important, if i had goten a more powerfull amp to begin with, i would have been able to upgrade sooner. so get a amp that you can upgrade your subs with later on in the future. you should also look into diffrent boxes, ported vs sealed vs bandpass. with some boxes built correctly you can make 2 12's sound like 4 15's. and lastly you should plan on dynamating your trunk. pretty much all carprices sound like crap without it. i think its embarising to hear a car driving by that is making that noise and you will not only sound good but you will look good, which is what you want right?

thanks to everyone for the info i really apreciate it. I still havent decicded on an amp yet but as far as the hifonics brutus amp, what are some of the pros and cons? why were'nt  you impressed? the guy at a local shop sells these hifonics amps and said that they were good amps. He also sells audiopipe amps and speakers, he installed some audiopipe 12" 800watt speakers and an audiopipe 1600watt amp in my cousins car and as far as the bass hits its crazy. I love it, i just want more i want to be louder than him.

i used it for my L7's and they did not hit at all, i went out and got a kicker one instead with the same output and the kicker one hit much much harder. im thinking the brutus was over rated. kickers amp came with a birthsheet and i kinda do turst that brand and i knew what i was getting with the kicker one. but dont get me wrong ithe brutus was a decent amp, i loved the blue color it does when it lights up and it does look pretty clean. but if you look around and see what people are saying (like a product review site) about any particular amp you are loooking at you can get a feel for what you are spending your money on. i just dont want you to wish later you want more and you will have to spend even more money.  i feel that what you might spend on your brutus amp you can get a little beter quality and maybe better out put.

All my vehicles with trunks were so sound proof I had to port to the cab. Bandpass lows were a hit feature at shows. Ported volume levels were good for driving by a high school.posted_image

i owned a brutus amp a few years back and all i can say is that it was good for the price i paid for it. but, as far as amps go, they are not great amps. they are slightly over rated and cant take much abuse. if you are doing this as a show off system the you will want an amp that can handle some abuse because there is nothing worse than blowing an amp while trying to show off to your friends. you get what you pay for, $250 for a 2000+ watt amp you do the math.

Ok I dont think I am going to get the brutus amp. Im going to just save a little more money so that i can get a quality amp, but I still have no idea what makes an amp quality. How can you tell just by the specs listed what should i look for?

i can recommend brands such as autotek, US amps, JL, JBL, Kicker(amps only), PPI, memphis, orion, alpine and thats just a few. you just need to not look at price first.

there are not too many specs that can tell you whether an amp is good or bad and as we know, spec are inflated all the time. aviod falling for marketing schemes like "PEAK WATTAGE" always look at RMS.

you can also just look at the build quality, notice the terminals, if they are claiming more than 2000W but the the amp only has 4gauge terminals then somethings not quite right. the only exception to this is some amps might have 2 sets of power and ground terminals so naturally they will be smaller.

you can look at the fuses on the outside. a 2000W amp should have about 80 amps worth of fuses.

also the weight of the amp can also tell you something about whats inside but you would need to go to a shop to get a feel for the amp. big power amps aren't usually very light.

the rule of thumb that a good amp should be about 1 dollar per watt isn't really that true anymore. there are plenty of good 2000 watt amps out there that are around $500 - $700, still not that cheap i know, but like i said, you get what you pay for.

I was looking at the alpine pdx amps, alot of people on here are very fond of them. I was thinking of going with the 1000 watt mono amp. with 2 15"  alpine type r's. I think that should sound pretty nice.

you can do that but you will need to get the dual 2 ohm version of those type R's to keep the amp happy.

I already knew that but thanks for the info. I actually found a jl 13.5w7 for a good price so i went with that. I was thinking about going with the jl 1000/1 amp or the apine pdx1000.1. havent really decided yet, I did want to know if anyone thinks that this one speaker will give out alot of bass and be really loud, or would you go with two? I know that jl is a good product but I know I can find 2 other great speakers for the price of the jl 13.5w7. the only reason I got that one is cause i got it for a very low price from a friend. If I was to get another one I would prolly have to pay over 500.00 at least.

that W7 is a beast in the right box. it should be all you need. but it did take 3 of them to beat my single 18 by a tenth of a decibel.

I'm not looking to compete or anything I just want to be heard before I am seen. Can this single sub do that? I seen some on you tube but you cant really tell how loud it is, it looks like it goes crazy but will it be heard at least a block away? the box that if came with the guy told me it was built to spec but when i looked on the jl website the box measurements are  about 1.5-2 inches smaller on each side than what is recommended. I will hook it up this weekend to see what it can do but i will most likely be building a bigger box, just dont know how big it should be. Does anyone know a link to where i can input the demisions I want the box to be and it can design a box for me. I need like a blueprint on how to build the box.

2 w7's of the zapco block(4k watts) "done right" gave a whole new meaning honda accord was on steroids having a seizure. Ofcourse there is always more...but goodness gracious, I'll never forget the sound, I've never heard ....nevermind Opiniarian: would say: "BOOM, Break the bank on your amp and wire. Get subs down the road." I think we started with 2-15's or 4-12's, now Im reading thoughts of 1-12" lonely lil sub? A hatchback might get a single sub to travel that far.

yeah that is true I was going to go with the alpine type r but i got the w7 for just about the same price as one I really want two w7 subs i just wanted to know if one would be enough, I know two would sound crazy but if i buy another one that would make my whole set up alot more money. i would prolly have to get 2 amps, extra baterry, ho alt. I guess I can save up some money to do it right. I would prolly end up upgrading anyways. cause in the end I WANT THE BOOM.
