I am an audio n00b, but if you are concerned with space+weight savings, and you only want one one small sub, you might as well get the most out of it, and point it towards the front. Seems perfectly logical to me :dunno:

Yes, LX, but what I was saying was I have seen almost ALL installs with sub boxes facing you when you open the trunk----with the subs firing outward, toward the trunk, not toward the rear seat---seems this causes what is known as a "bass wave" which can develop and double, and then reach the passenger compartment as heavy hitting bass...now, I dont know if this applies to SUVs and hatchbacks, where the rear cargo areas are all totally open....but I have seen coupes and sedans where the subs fire backwards towards the trunk.

Some have told me that firing subs toward the seats muffles the bass and it doesnt sound right that way....

That makes sense, since soft objects are always used as sound insulation...

i def second that suggestion, that would sound really good and give u exactly what u need.



also, dj scotty, ive tried facing mine towards rear and up towards deck. up towards deck sounds better to me cause i dont have any rear speakers so the speaker holes act as a port into a cabin of sorts. it also doesnt make the trunk rattle as much.

Yeah, I can see that....that's why a lot of hatchback boxes, such as Kicker's CTF (Camaro, Trans Am, Firebird), are angled to fire upward on an angle...but in a trunk, the only way to get that angled bass air into the cabin is to remove the rear speakers, like you did....

the box is made of fiberglass.. it is then sanded, bondo'd and covered with a layer of gel coat (i think that's what it's call). the gel coat dries clear but rubbery. so, i sprayed a few layers of automotive clear coat to make the surface tac-free.

I'm interested in installing a sub but I don't want a space hogging big ass box in my trunk. I'm not really big into audio but I do want to add some low end punch without being crazy loud. My idea is to install a free air sub directly behind the fold down armrest in the trunk. This will allow the bass to enter the cabin while the armrest is down and the little door that goes into the trunk is open. Will this work? Again I'm only interested in adding some good bass without being the King of Krunk. Any of you audiophiles have any suggestions? Crutchfield sells a Kenwood free air sub that I think would work good. Can I use that with a good amp (suggestion welcome on a amp also) and also use the rear 6x9's? I dont know much about car audio so help me out with some good intel. Thanks!
if you wanna keep as much trunk space as possible, you could do something similar to mine...just not quite as extreme. i glassed my spare tire well & put (1) 15, but it could be done the same with a 10 or 12....you just wouldn't have to raise the floor as much, maybe none @ all.

i use a memphis 500d for the sub (about 700 watts). i have a memphis 75x2 for the front seperates & the memphis 6x9s on the rear deck are run off the head unit for just a little rear fill & i have 'em mostly faded out.

holla back if you have any questions

I see that you guys who provided pics of your subs in their boxes have the boxes up against the rear seat, with the woofers firing toward the trunk, out at you when you open the trunk---this is how I have my huge sealed box with my two Fosgate 15's, and yet I always wondered if this is the right way to face the box---in a closed-trunk vehicle, such as a sedan or coupe, should a sub box fire backward, toward the trunk area, as we all have it, or should the woofers fire into the seats, forward? I have heard so many theories on this; that by firing the woofers the way we do it, it creates a "bass wave" off the trunk lip that develops and then fires back into the passenger cabin, providing more boom. But, I have also heard, that in vehicles like hatchbacks and SUVs, subwoofer boxes can fire forward toward the passenger area because it's all open back there---the bass isnt trapped in a closed trunk....is this so?

usually when you reflect the bass off a solid object (ie rear wall of trunk or rear window) you typically will gain upto 3db. this is why it sounds better...cause it is typically louder.

BUT, is facing subwoofers FORWARD, so you can see them, actually firing the bass FORWARD too? In other words, in a typical subwoofer box, when you look at the subs HEAD ON, is THAT the direction the bass will be firing? No bass comes from the BACK END of a subwoofer box at all? So therefore, facing subs to see them when you open a trunk (head on) is going to make the bass hit that rear wall of the trunk because the subs are FACING that way, and then the bass wave will couple, causing up to a 3dB gain?

yea SOME bass will be coming out the rear but the majority is coming from the front of the cone area. since bass is non-directional, sound wise it won't matter if they face front or rear, but there is a larger volume of frequencies coming from the front of the cone since there isn't wood, poly fill, etc to absorb the waves. hence more to reflect & louder volume
