Title: sub box idea behind the bench seat
Post by: 1983stepside on December 02, 2008, 06:36:16 pm
hi im kinda new to this site and building a cool truck im wanting to either build or buy (rather build save money) a sub box couple problems i have are
1 im not sure what size would sound good i was thinkin 8 or 10 inch subs would be good with new speakers in the  dash and some how speakers under my vents near the floor on the pass side and by the parking brake on the driver side not sure the proper name for them besides vents  :-\ any help,ideas,pics or all of the above would be great thanks

I've been out of the stereo stuff for quite some time but I bought a set of 8" subs once and couldn't slide my seat back all the way.  I took them out to build my own box and the speakers themselves with no box wouldn't let the seat slide back all the way.  So, I don't have them anymore.  I have always meant to get a set of flat subs that are electronic.  I have heard they are very compact for what they do.  I had a set of 6x9 cerwin vega's that sounded so good in a cavalier I had I couldn't believe it.  I put sound mat around the cab corners and built custom boxes for them with a vent tube and all, they sound pretty bad in there.  I have a set of high end boston acustics in my 80, also sounds bad.  I have almost given up on making one of these truck sound good with a stereo so it will be interesting if anyone has some good advise.

No I don't have a pic of the ones I built and that truck is at the fairgrounds in storage so I can't get you one.  I bought a kit somewhere a long time ago to put 6x9's in my 80.  I like the one I built better, I used plexy glass and turned out very well.

I should add if you have a custom seat instead of a bench it will open up all kinds of room for a sub

Check out my page for some ideas. Page 6 under my 1997 Avenger shows my old system. Under my yellow truck's own page is some pics of the new console setup I'm building to hold 1 12"

http://www.cardomain.com/id/sux2bu99

I've seen 4 8's in these trucks, and 2 10's + 2 12's all in 1 box, but the depth behind the seat usually limits a person to using 8" subs or maybe shallow 10s. There are shallow-depth 12s out there too and I've heard good things about the JL Audio 'flat' subs. They are under 3" deep and 3" is about the depth limit at the bottom that you would want to avoid moving your seat.

Check out the Memphis S-class shallow mount subs. Memphis is known for big bass in small enclosures. I have two PR10's under the rear seat of my extended cab coupled with a 1000D and it is all you would ever want.

i have a shallow pioneer 10" sub behind my stock seat. i need to have the seat all the way back otherwise i cant really drive it and i have about 1" b4 the seat touches the sub box at the top. i found a really shallow box (2nd one i had to buy grrr) at "visions electronics" that mated with the shallow sub perfectly. sounds good too with my crappy amp!  i also have four 6x9's in the back with a stiffening cap. no room behind there for nothing else haha.  i dont know how to upload pics here so i guess its time to use the search function lol

i have two full size 10s. there are a few shallow 12s that you can get now. rockford, kenwood, kicker, jl all make them they are kinda expensive though.

I put buckets in my truck so I could run a sub while sitting normal.  If you could do buckets, I'd get a hold of fisher customs.  www.fishercustoms.com  He made me a sick box for my Cutlass and his quality is excellent.

as soon as i get enough money im going to get shallow mount 12s then i wont have to have as far up and it will hit really hard ;D ;)

Look into Stereo Integrity Magnum D2's.  They're awesome subs.  www.stereointegrity.com
Title: Re: sub box idea behind the bench seat
Post by: bigblue09 on December 17, 2008, 11:10:42 am
it says they are out of them. i will probably go with the kicker ones or the rockford ones. i can get the kicker shallow 12s for like 140 a piece and i just have to modify the box i have now and im good to go.

Wanna be really cool?  I know where you can get some awesome 8" subs.  No body I know runs them but me around here.  www.Sundownaudio.com  Kicker and Rockford subs are not that great.  Those SI's and the Sundowns would walk all over them.

Title: Re: sub box idea behind the bench seat
Post by: grinder1989 on December 17, 2008, 04:44:26 pm
I'm still working on that issue myself.  Let me know when your ready to get some 8's.  I could get you a killer deal on some Sundowns.

rockford is one of the best sub companies out there! i have 61/2s in my doors. there is a custom made box they are in. it works good. (pics on first page) i have a 4 channel amp running my subs and my mids and highs. works pretty good. i might get a mono amp for the subs to get more and change the 4 channel to 2 and do mids and highs with it.

Post by: grinder1989 on December 18, 2008, 12:07:10 am
You are very sadly mistaken if you think RF build the "best subs out there".  By no means am I trying to be rude because I love stereo's but I really think you should look into some other brands that make 8's like Sundown, Digital Designs, Image Dynamics to name a few.  They all make excellent products that are far better than anything Rockford has made.  I will ship you my personal 8'' Sundowns if you'd like to demo them in your truck :).

I had 2 MA Audio 12's with an amprack all behind my seat and my seat went all the way back its all just in figuring the angles, depths, and required air space. Also sealed boxes always require less space? Another option for you would maybe be 1 12. I have a 12 foot table saw which sure helped with it. Same thing could be done with a circular saw.

I molded a box out of fiberglass that holds a Kicker 12 inch shallow mount, a couple amps and a small storage space.  Check out the write up http://67-72chevytrucks.com/vboard/showthread.php?t=319401 (http://67-72chevytrucks.com/vboard/showthread.php?t=319401)

I have 2 12" Kicker Comps and my seat is just a tad pushed forward. Almost all the way back though. Doesn't hit too bad off of a Boss 800W amp. Got the box from the Flea Market, it's just a run-of-the-mill regular cab box.

or you can do what i did and just port your bed and cab... and from there you can decide if you want to go with 10's or higher....also depending on what seats you have you may be able to fit 6x9's on back corner of cab where theres nothign there ... i mean as far as everythign go's im running 800wts to 2 kicker 10in L7's bridged and they hit hard enouph ...but i mean if you really want slap just go with a bigger amp!

I'm running a 12 behind the seat in a angled box that I bought at your average stereo shop. It turned out really well. Now I just have to get rid of all the rattles.

Post by: bigblue09 on January 15, 2009, 08:58:02 pm
