Im showing a 1995 celica hatch and in the last few shows the judges havent been giving me very many stereo points... I currently have 3 Jl audio w6's in a custom trunk powered by a 1000 watt concept amp.... I want to tear it all out and redo the trunk to fiberglass, but if I am spending that much money I want to upgrade the system... my goal is to hit over 160 db's and I can fit up to 4-10's, 3-12's, or 2-15's in my trunk... I am building the trunk myself and I wanted to make it sealed cause it looks alot cleaner... I was wondering if this is possible without haveing to spend an insane amount of money such as buying 3-amlumapro's or 3-w7... any advice helps

if you trust ebay...you'll get the W7 13.5 in sub lil cheaper.

its all in the encloser...i know out there in the audio world,someone made a computer program that you can build a box and stuff. I would concider having a computer made box built.

there are alot of subs around these days that would help you achieve your goal, but alot of knowhow goes into building a 160 db system...

regardless of anything, you are going to need power...lots of it...big alternator, big battery(ies), big amps...and a big ported enclosure would help you out in most scenarios...

give me a rough budget for subs and amps and I will attempt to help you out with your project...

personally I hit 158db with a single Stroker 18, but there is soooo much between 158 and 160...it is really amazing...

Ya cuz a 3db gain is basicly doubling your sound

-------------
What?

well I have an audio control matrix line driver, A yellow top under the hood, and a 200 farad bat cap, I am just seeing what subs and amp I would need for a 160 db system... what do you have running your stroker 18? .... and is it imparative that I make a ported box to reach my goal or is it possible to do in a sealed one?

ported is alot easier to hit big numbers...

I had a mmats d200hc on my Stroker...

like I said, give me a rough budget to work with and I will see what I can offer up for you...

For subs and amp my budget is about $900... I had an offer to get 3-12 L7's and 3-500a2's for $900, but I heard that I prolly wouldn't get over 140 db's in a sealed box and even if I ported it it, it still wouldn't get over 150...any truth to that?... also with that budget what should I do?

well, honestly, 160db would be almost a miracle unless you bought used equipment, and even then only if you got a really good deal...

if you really want to hit 160 db, 900 is more like one or the other...subs or amp...and then expect to spend that again on the other...

and that is after you have already spent the money on upgrading your electrical system and bought all of the wires and distro blocks and other means necessary for your install...

yeah I have already bought everything else, just need to get sub and amp ideas cause I have another show coming up on the 23rd and I would like to get my box built... what subs are the most bang for the buck, and work good in either sealed or ported? (I suppose I could find a way to port)... and how many watts do I need to run them?.... are l7's the answer or are there better subs for the money?... just looking for some advice

If you were nuts, you'd step up to a couple of Solo X's and run 5000 rms to each!! I think you'd be over your budget though...

ive heard farts that sound better than those. if any of us only cared about SPL which IMO is a waste of time. then sure solo x's would be nice...however id use a DD over the solo waste of space giant paperweight that requires gobs of power to do anything. and all for a 1 note wonder.

lol... I was just looking at tht DD and the guy said he hit 152 db's with one sub with a hiphonics 1000 watt amp hooked to it, so would DD be the way to go?.... I was also checking out shockers x-treme's... anyone heard anything about them?

Consider buying a killer amp kit and using your existing subs. You might fry them, but you would be buying enough time to enlarge your budget.

Tell Darwin I sent you.

I've been sick lately, sorry I won't be on much.

you could try 2 15 power Hx2s both running off a 1001bd

dream it, build it, fiberglass it

I had that set up and the most I hit was 155 in a sealed box, 2.2 cubic feet per sub, in a civic.

i heard 2 shocker extremes 18;s, they 163 with 8 ample audio amps

PureRF has a good idea posted_image

What?

I know exactly how to hit 160 db. I dont know if you have heard of a MTX RFL butif u havent it weighs 56 lbs and has 4.35 inches of excursion. It handles 2000 watts rms and maxes at 4000 watts. You could get that sub (https://www.outerlimitsaudio.com/product.cfm?Productid=3786) go there but u can probly find better prices, and run it off 2 JBL BP1200.1s (www.etronics.com) The rfl is made purely for spl and thats it, a friend of mine broke every single window in his car in one hit. I would suggest a 2 farad cap for it too.

o yea forgot to mention that you would def put it in a ported box of 1 inch MDF with a ton of screws and all that stuff. hope you take my idea i promise u cant go wrong with it

lol puerRF where do you come from?

any serious installer will see your glass breaking story and probably laugh as hard as I did when they read it...and at this point I must say that I think you are full of crap as well...

as for hitting 160 db, you could look at Beyond Audio Inhumans, Diamond TDXs, Shocker Extremes, Resonant Engineering XXXs, the RFL, the Cerwin Vega Strokers, or the jl w7s to start...I am not sure where each one fits into your budget, but they would all make it relatively easy to hit 160 with some good equipment to back it up...and of course, a little know how...

no offense man but you have NO idea what you are talking about. first off the MTX RFL does not even come close to half of the "4.35" inches of xmax...

maybe suspension can handle it...but the sub wasnt designed to push it that far magnetically thus it will fall far short of those values linearly with a horrible BL curve to boot. the sub has one of the worst sd's out of any "supersub" out there...especially for the price they cost. go with a 9915 ported on two 2.5kw amps and you'll be happy and louder than an MTX

I have 2 Sony Xplod 1236L subwoofer, 12 inch, how can i gain for 125db in my mitshubitshi lancer Evo3? any suggestion? how should i get my enclosure done?

-------------
Thank You!

get better subs for one...sony sucks.lol...

JL audio W0's are good subs.

First off it can and will go 4.35 from lowest to highest. and the guyt hat broke his windows had 2 hooked up at about 2000W each. it happen i saw it?

second off...IT CANT. do i really have to get into this you are sounding like a total ignoramus. subwoofers have different ratings which derive their "excursion" capabilities. to start the RFL has only 1 value that would allow 4.35 inches of throw...which is the xsus (mechanical capability)...but the magnetic capability (xmag) cannot throw the cone that far without falling out of the gap and resulting in pure crap for sound. its not scientifically possible to get that shoddy sub to move that far. and even if it could. the subwoofers 'sd' (effective piston area) AKA the thing that moves air is horribly small. (almost the equivalent of only a 10 inch subwoofer. rather pathetic if you ask me.

care to pull another quote out of your ace?

-mje-

I hit 160db with four 12-inch kicker l7's and two kicker zr-1000. Dynomate the whole trunk and put a few batteries a real good alternater and battery isolater.

do you guys think that i could get somewhere in the high 150's with 3 l7 12's and a kx1200.1 and 600.1?? im putting them in the box size that kicker recommends for spl or deep bass. 3.25 sq ft. or any suggestions on what could be louder i got about 1500 bucks to work wit thanks.

Wes

you gonna be goin to contests...or this just for sh*ts in giggles?

I say buy what you can pay for and have money left over to put into the alt and battery. its gonna suck up power like no other.

lemme clue you guys on to a little something. first off you could hit 160 even 170 if you were good enough :) with just 1 subwoofer...nevermind 3 or 4.

its all in the install...heres a hint for you (to create "SPL" (sound pressure level)...you need to compress air. the more area you take up in the car or truck or whatever (wall installations etc etc...cementing the insides of your doors blase blah will decrease your cabin sq area by a good sized amount. coupled together with the right box, and adequate power...and you'll break 160s with just 1 sub :)

however a real man can break 150 with about an 18 hertz beat. lemme know how it goes

-MJE-

hehehe....^ starts a new revolution for the metro hatch back..lmao..

I saw somewhere with one sub a guy hit 158 in a 1979 honda civic....hey i got one of those....hmmmmm. that car is a good base for SPL...the whole back is spacious. Too bad mines a rust bucket. stupid winter and salt.
