I couldn't find this in a simple google search. I have 3 12" subs facing towards the trunk. Right now I need to replace my trunk. Basically will the subwoofers "damage" a Carbon Fiber trunk causing it to warp and become wavy?

if so WTF!? thanks

I think you'll be fine, Phil. I've never heard of CF warping from subs. I'm not 100% sure, though.

Try it out and let us know! I'm sure the company who makes the CF trunk has a warranty of some sort.

how in the world did u fit 3 12s in a cl?

I agree with princelybug I dont think you'll warp the cf.Not to say with enough power you might be able to crack the cf at mounting points.Trunk arms,Latch.

3 12'sa is easy custom box.

I'm sure it wouldn't warp the CF, only heat should be able to do that, however with enough pressure if you don't vent it, the air will try to find the weakest point of exit which could be your mounts or latch

Yes and no... There should be a vent of some kind in the trunk to help let pressure out of the trunk when you shut the doors and that kind of thing. This will be the easiest escape for the air from the subs. But you are right about the heat warping the CF...

Or, OP, you could just seal the trunk off from the cabin, and do a box that is front facing sub/ports. When properly sealed, that gives you the least amount of pressure in the trunk, and should get the loudest inside as well... However, you're going to likely have to take out the rear seat bracket...

my trunk is already done, i have 3 subs its just so much work to redo a custom trunk. i like it, but if i were to do it again, i'd throw in 2 10's or 2 12's and just do a simple box, but it would be facing up to "save" trunk space.

i'll take it into consideration.

mattastick

facing up is not the way to get loud from a trunk, fyi...

i know and i can tell lol. show reasons mainly.

mattastick

yeah, that'll happen... Pics of said setup? I don't believe I've ever seen it...

eggyhustles

depends

sub up port back is

mattastick

In a hatchback or SUV, yes... From a trunk, it's not the loudest... Because if your sub is up, it's likely firing straight at the the trunk lid. This is the weakest point of the trunk, so you're going to lose a lot of SPL that way... On the other hand, sub/port forward and sealed off from the rest of the trunk is ideally the way to go. That way, you can build your box to spec, and you don't have to worry about losing pressure to the outside air as much. Also, you have less "stuff" in the way of the sound waves on their way into the cabin. Another thing is that you have a smaller space to pressurize so you need less cone area, port area, and power to get the same SPL out of the car. The only problem is that it would likely raise the peak frequency of the car, and if you're tuned low, this could cause a peak in music at certain frequencies... Nothing a good EQ can't fix though...

Im my younger years I had a 97 accord with a CF trunk, and I ran 2 12's facing back with 1000 watts and never had a problem with warping or cracking. Just make sure to use LOTS of dynamat or it will rattle like a bitch, the light weight aspect of the CF makes it prone to rattles.

CF will rattle bad with subs. Dynamat and new seals are your friend. Flip those around so they're firing at the rear of the vehicle - you'll get better resonance that way.

I had 2 rear firing 12s in my CLP, only on a little 4 ohm stable 2x250 Orion Cobalt - and it was enough to pound it home.
