Placing the subs

Im thinking about putting in two TS-W28C 10" 400 Watt Subwoofer's in my car. The only thing is, i dont know where to put them. i posted some pics below of where i am thinking about putting them, but i dont know if the would work.

Pic 1:

I dont know if this one would work because i dont know what is behind that little hump. would the speaker fit in their? I have already mesured it and it would fit circumference wise but i dont know about depth wise or if it would sound good with the seat folded back. Any thoughts?

Again i mesured but don't know about the depth thing, and also about the t-top case resting on them with the t-tops in them. i thought about making a box like alot of people are doing but i need a little trunk space.

Get a sub box that will fill in the space between the gas tank and the rear of the car.

Bret,

I thought about doing that but i need some trunk space. Its my daily driver and i go on trips quit a bit and not everything will fit in the back seat.

Anyone have some other ideas of getting a really good stereo system in my car for a reasonable price? Size, where to put them and type of speakers.

Thanks!

How about some Bazooka Bass Tubes? Maybe you could hide them somewhere?

There is no good place for subs if you want to keep the spare tire and trunk room. The car just isn't big enough. You have to use smaller subs if you want to hide them. I know a guy who has two tubes mounted on top of the gas tank that don't obstruct the view real bad and hit mega hard. That's the only way around it right now. I'm currently working on a place to mount a box w/ two 8s, but that isn't going so well.

Im going to figure out a way to turn a 12" sub into a sterring wheel. Oh yes, I will find a way. LOL

In all seriousness, these have to be one of the most difficult cars that ive seen to put a system in. With how oddly the back well is shaped and limited room throughout the car, theres really limited choices of where the box should be located.

speakers i have now

These are the factory speakers. I have a gain switch with the "Performance Sound" option but my subs are poping. If i replace these (plus whatever is in the dash)(does anybody know what size the ones in the dash are?) with some good speakers this would this sound really good? The sizes of these are 4x6 (top) 5 (bottom).

Thanks!

I would just pull those rear speakers and get 6x9's there like most people do. The stock front speakers are 4x6's, but I recomend just getting kick pannels. Most all of your questions could be answered by doing a search.

I agree get some good 6 x 9 and try to stay away from the 4x6
get the kick pannels that hold componets and you will get much better sound.

Ok here it is. I would build a board out of 1/2 inch plywood and shape it to the rear contours of the back panel of the trunk. It actually makes it look like the well is gone cause the board just seals it off. you can put 12's or 10's or whatever you want in there. Use a hinge to mount it to the flat area of the tanks top (or the hatch's bottom, which ever you call it). A long skinny one would work well. Put a handle on the board and you can still use the well a little. Also put some grills on the tops of the speakers and you can still use all of the top portion of the hatch area. Mount the amp to the underside of the board for better cargo saving.

Well, first of all, plates suck. You will never get good sound from a plate. Subs need a sealed box (in some cases ported) in order to sound the best, and if you only have one side, your not going to have a seal. Second of all, never use plywood for subs, especially whimpy 1/2 inch junk. It is not dense enough, nor strong enough for applications involving subs.

Hey cheese head!!

If you bother to read the post than you would know that he is looking to save space. A huge sealed box will not work!!
I have used a plate/ board that was half inch ACE plywood. Thats the more solid stuff not particle board. It held up fine an I cut two 12" holes and a 9"x10" square out of it. Throw a little colormatched carpet on it and your set. Just put in some free air subs too. I agree though they are not the loudest they still hit very hard. TRUST ME.

What you really need to do is find the Bose decklid and kicks. Then you can mount some 8s where the 6X9s used to be(maybe ). I think I should investigate this some more. I'm starting to like it.

why not use a real nice single 12" sub... and build a small sealed enclosure that faces one side of the well, tucked off to the side, but doesnt take up the whole well of space... if you could get a sub that can be used in a really small box that might be able to work. im getting image dynamics IDQ 12's, and they work in .65-1 cubic foot boxes, pretty small compared to some out there. just a thought.

That's a tiny little box for a 12. My pioneers need a foot and a half sealed.

I'm not going to argue about plates being lame and the complications of mounting subs in your gas tank. You could however put 2-10" subs easily in a sealed box ON TOP of the gas tank and still have a trunk.

What kind of subs need a sealed box? If the sub is set up for a free-air type set up it should still work on an infanite (sp?) baffle type set up shouldn't it? As long as the sound coming off the front of the speaker doesn't get to the back of the speaker it should be ok if it's a free-air sub shouldn't it?

I heard that MTX use to make a plate to go in the back of thirdgen's. It rocked pretty hard from what I hear.

My brother was telling me about this one guy who had a car that had a very big deck lid area (whatever that area in the back window of a regular type car is called) and the guy had 2 Power Rockford 12's and one Power Rockford 18 mounted on it. I think he was using something like a Power 650 Rockford to power the subs or something like that.

He was running them free air and was pushing a lot of power to them. My brother told me they rocked really hard and went so loud without distorting that it was freaking amazing. After hearing stuff like that it makes me wonder if doing a plate/free air sub set up could work if done right.

I dunno, just commenting.

Ted

Thank ***

I'm glad someone realized the gas tank was there!

P.S. It's either trunk space or bass. U have to make that decision.
As for me. My T-Tops no long come off!...

Here's a thought

You could install a sealed box in the rear well, that is an inch or two lower than the gas tank "hump"

Then, as a variation on the hinged plate idea, install a blank hinged plate which, when open, rests on the gas tank area, and when closed, covers the sub box and allows things to be stored on top.

As an added bonus, it hides the subs when you park in a "questionable" neighborhood.

Damn I think I'll do that!

Who needs 6x9's to replace those stock speakers? I didnt feel like taking the whole panel off and making a new one to hold 6x9's, so what i did was buy new 4x6's and under that put 4" component speakers under it. Sounds great .. all the treble i need w/ the bass from subs
