doooont mount it upside downn!!! =/ thats asking for trouble especially in florida heat. avoid that until its like your absolute last alternative. Mounting under a seat would be better than upside down uder the rear deck.

 

^ Dammit. You'd think they would make amps to satisfy these kinds of requirements that could be hidden away. Okay, so, how is MTX in relation to an Alpine Type S? I'd like to make the box a wedge and turn it so the speaker is facing the seats. Then I could try to find an amp that could fit and be mounted on the side of the box. Worst comes to worst if the amp won't fit on the side of a wedge I'll make it a bit different, so if you were looking at the box from the side it would look like this (sorry, no graphics programs at work):

That sound feasable? If so, I guess where can I get info on specs I'd need, or is there a pre-fabbed fox that would fit what I wanted? Terminals on one of the sides where I would mount the amp are always a plus.

 

Amp is behind a lip on the box totally invisible
Sub faces seats. Simple & clean. The footprint for the amp is about 10x8 so you will need at least a 10" depth on the enclosure to hide the amp. You need at least that much area for any decent volume anyways.

I wouldnt try to slope the box on the inside - facing the woofer towards the seat is bad enough, putting the woofer parallel to the rear seat will sound even worse.

 

Okay, so a cubed box is a must, and a lip in front of the amp is the best way to hide it, gotchya. On the issue of facing it towards the seats being a bad idea altogether, I realize that I'm getting into some complicated stuff and might need to enlist the assistance of someone with more woodshop skills than me. How about sinking the sub into the box a bit? Make a large hole, and then put an MDF ring on the inside of that hole to mount the sub into. That way it could sink into the box and then I could simply cover some generic 10 or 12 inch speaker grille with carpet and lay it over the sub to get a flush, carpeted look. I know I'm sounding kinda unreasonably anal, but I want it to look like just a lump in the trunk if at all possible. Or is that a waste of energy and I midas well just turn it around to face the seat and it won't be so bad? Since the seat goes up and down the sub will be parallel to it pretty much no matter what if its facing them.

 

face it towards the seat and call it a day.

Flushing is not hard however, if you chose to face it towards the rear you simply cut the hole for the inner sub out of one square, and cut an entirely new piece with a larger hole to shroud the woofer and drill it over the front. Using this technique you could actually hide the amp under the face on the side as well if you wanted to get a little more room.

 

Hmm, flushing the amp doesn't sound like a bad idea. Obviously I'm guessing don't carpet over the amp, but hell, I could face the amp towards the seat so nobody would see it on the back of the amp, flush it down, and then do that with the subwoofer. I think that'd give a very clean look, alls you'd see is an odd bump right in the middle of the trunk up against the seats. Any brand of amp that puts out less heat than another, or is more efficent at dissipating heat in a small space - such a little amp shouldn't give me too much of a problem anyways?

 

and smaller class D amp should serve your purpose. Keep in mind, horizontally(as in the top of the box) mounted amps will be able to dissipate the most heat no matter what. heat will always rise.

 

Mkay. I've also heard that its not always good to have just a box, that the sound needs angles and whatnot to bounce off of. Are these statements just false, or should I put some baffles in the box, or what? If you have a link to any sites on designing your own, know of any premade that I could modify slightly and then would work awesome, or have any further adtive to add on box making, please lmk.

 

what about a false floor? i know thats not "hiding" the subs but it doesnt "stick out like a sore thumb" either

 

a perfect enclosure has no flat angles at all - the worst is a cube.

whether or not you can hear the difference is the million dollar question.
