Sub box/audio questions

[1LowToy]

I'm going to build a speaker box for behind the seat. I'm thinking an 8" or 10" but space is limited. I was wondering how deep are the speakers 8 or 10"?

I'm building my box, hopefully once

Honestly, they vary alot. They have slim subs that take up much less room that a regular sub for shallow mount needs. Do a search and you'll find a very wide range of depths. Good luck.

yea they call them pancake subs. pioneer makes a 12 that i pushed behind the passenger seat in s10. it hit pretty hard. but 2 8s will punish a 12 in a lil space like that and u will more music cuz it not trying to push air thats not there

Well I've cut up some materials to frame up a box. It's going to cover the full width of the back of the cab. The wife asked if I was going to build in storage That's what the back of a truck is for honey

I found a speaker laying around so I'm going to use it as a guide and may use it as it fits the plan so far. My question is now should I beaf up the center woofer area more on the front surface area or will glassing the 1/4 ply be sufficient? I know more is better but when do I say when. Here's a couple of pics

opps!

ive got 2 12s behind mine. found a suv box just be sure its slanted in the front and cut the back of it, seal it back up and enjoy lol

Looks like it would be fine, especially if some of the screws holding the sub to the box can get screwed into the side supports.

no dont use ply wood. bad idea. use MDF board it dont cost much but its the ideal material for building boxs. something about mdf board allowing air to move... just dont use plywood its a waste of time. the frame u got is fine. just put the back on then chalk the inside of the box. remember to put some kind of gasket where the speaker meets the box. most speackers have one made on it. otherwise it will clap

[1LowToy]

MDF?? More Darn Finances? Who knows that may be what I have there. The spacing of the frame are not fastened yet. They ar just supporting the speaker for the moment.

I built an ok looking box. I bought a sheet of 3/4 inch MDF and took some simple measurements... The box has 2 6x9s on each side of a 8" subwoofer... it sounds pretty good. It sure does sound better with the seat folded forward. The seat muffles a lot of the quality. I have a 600 watt amp that is put in its own section of the box, with a separator between the amp section and the speaker section... It was fun to build. It's coated in rubberized undercoating. Here's a pic.

And what's wrong with framed, supported and glassed ply board?

[dv8customs]

If it is 1/4" it is too thin no matter what you are using. Using 3/4" MDF would be best. You mentioned glassing it, what is the plan for that?

Check me out custom box for the JL 13TW5 this thing bumps power with a JL 500/1

The idea of framing sealing and glassing it would be to stop any vibration the same as the partical board. This way it will be light, moisture resistant and sturdy. I plan in insullating the interior of the box and as you see the curved ends to fit snugly to the back of the cab. Utilizing as much sealed speaker space as possible. The side speakers will have a smaller area and the drivers side will also hold the head unit so I will have no dash unit. Most of the new decks now are remote so why look at it? I'm reall not interested in CDs so a thumb drive or Ipod is the way to go. On top of all that the wife can't change the station (I hate elevator music)

i'd contact the maker of the speaker/check website at least
some sound better in a box made for them(air space)
some need a port, some work open
don't bother with plywood,MDF for sure....think mine was 5/8th
used wood glue on all inside seems,like caulking with counter sunk screws...
almost twenty years still holding up,mine r 10s
make sure to get grill covers....

Yes, definitely MDF for the subbox material. There's something about the acoustic properties of the material, it absorbs vibration better or something like that. I've used 3/4 birch plywood before as well, I was told once that either would do just fine. However most used MDF.

Most subs come with recommended enclosure dimensions, if you google the make/model of the sub then you should be able to find what you're looking for.

I've used JL audio subs in a few vehicles and they have a .pdf of the installation instructions available from their site that shows everything you'd want to know about building a box.

I think I may just cut a hole in the floor of the truck and mount it there

Just kidding. I'm going to check out the recommended size of box again. I built the last box (per manufacturers specs) for another truck and the new box that I'm building has the same interior area

[stroker87]

as stated MDF is a must or the box will flex and rattle VERY ANNOYING! make sure you SEAL the box very good if it leaks air you'll get noises or even a whistle out of it and the woofer will not preform well

you need to build it for the bass you like ("ported" heavy loud bass slower response or "seal" fast tight hard hitting) and use the spec's for the woofer your using, I've built boxes for the square bodies a few time 12 will fit but the vinyl on the back of the bench muffles the sound since there so close to the seat and if the woofer touches the seat (when it fires) its not going to last long if your really into sound quality 2 hi end 10inch woofers and a mono amp with the right wiring will amaze you in that truck

i have two kenwood 10" sub behind my seat. plus two 6x9. most 10 only ne 1 cu. ft. of space. my boxes messure 22" wide 15.5" high 9" deap on the bottom and 5" deep on the top. its made out of 3/4 MDF. i also have a box thats hold my amp and cap behide the seat. if you research how to build these thing its really easy. and use the right stuff the frist time.

[atarijake]

I attached my subs using t-nuts, example: http://bit.ly/AnSyEJ

This worked very well, stroker87 is absolutely right, make sure the box is sealed very well. I even went so far as to put some sealant between the woofer and the box. I forgot where I got it, but it stayed gooey and did a great job sealing the sub to the box.

This is a ported box for 2 JL 8s we are putting in my sons truck as we speak. Had it in another and it sounded damn good.

I like that!
Especially how the subs are low and somewhat protected.
I had a pair of 10's behind the seat in my 80 RCSB.
I'm long legged, with the seat all the way back the subs self-destructed very quick. They were hitting the back of the seat and destroyed the cone surround.

I like the design but I would rather have the subs on the out side in stead of the middle since the seat muffles the subs SQ

btw have any of you used bazooka tubes in your single cab trucks? I had some 8's in one of my single cab trucks and they rocked was not much of a differents between those and the 12's i had in the same truck just thought I'd mention it

[All Biz]

Hey I like that setup you have
