Doesn't that only happen in extreme cars and the few others that are loaded off the air in the car?

lol, that would be cool if it was a sub with a hole in it! But unfortunately it's just a 4" sitting on an 18"

I'd do subs up, port back, like Steve. That configuration seems to work the best for a non-wall in SUVs. If it's got 4 cubes per woofer and it's not tuned between 30ish and 35ish hz then ask him to change the tuning, but if they don't have 4 cubes each, your kinda screwed. Check back here with the info he gives you though. I'd get another one of the 5k Atomics, they are great amps, very worth keeping.

If it's sealed off, you shouldn't need any deadener in the trunk. BTW, removing the back seats is more fun

Doesn't look like enough port area, also, whats it tuned to? Should be 32hz. It has to be bad box design, because bigger boxes need less power because they are more efficient. Also, it looks like a really bad place for the amp, especially if there is no cooling fans behind that panel.

Just a quick idea you probably want 4 cubes per woofer for 15"s

0.75"mdf will fail, change it to 1.5", otherwise, it looks good.

Lose the back seats!

not enough port area, see where it say port area range? You port area should to be between those numbers.

A ported box will be great, also, shop around for some deals, all that for $7000 is a bit dodgy. I know how expensive stuff gets when you live down here (NZ), but I managed to find my amps second hand at give away prices (3Kw mono Atomic $900, 80w 2chan Atomic $100) both are amazing prices for super great amps (internally the same a Sundown). So I suggest having a look around on Australian car audio forums and find some cool bassheads nearby that will help you find deals. I can design a ported box for you if you want.

If you're careful with the gains it will be fine. Also, you will have a hard time finding a amp for $150

So that it makes a L shape like that. Except it will bend up on yours.

The port would have to bend when it hit the back of the box but otherwise, yep

You could make it height: 6 width: 20 length: 25 thats tuned to 30hz before you take away woofer volume and any bracing.

A bit big, ~8 cubes would be better. You have ~11. And port has too much area. With a port like that it is impossible to tune it to 30hz (and 6"s makes it 48hz) Fix those to things and you will be good.

I say back of the seat.

^ You can't be serious, it doesn't have to make power, just supply it. Why else does everyone add more batteries?

Don't fold your seats forward, it will be super uncomfortable if anyone has to sit there. Building around the wheel wells will be a pain, but it will give you more space. Where will the amp be going?

Yep, I don't exist. I said there isn't a awfully large amount of space back there, you can squeeze 8 cubes out of it, but there won't be much room for the port to breathe.

I got height: 20 width: 37.5 (that would probably fit a battery on each side of the box or both on one side) depth: 22 port height: 4 port width: 15 port length: 25 Thats tuned to 31.4hz using 1.5" thick wood. which is probably minimum for 2 XL 15"s. It's really pushing it on port area and box volume for those woofers though. Might be able to come up with something better if I spent some time on it though.

You sure that ain't dinner? lol jk Really though, it's sad how this is how the majority of sony xplod amplifier outputs look

Depends, have a look on youtube at videos of people blowing subs, some last for 5 minutes, some blow instantly. I depends on amount of overpowering and amount of clipping. I can give x subwoofer 200RMS more, and it will be fine, but if it is even slightly clipped, it will blow after a minute. But if I also give x subwoofer 400RMS more, even if it's clean, it will still blow after a minute. But give x subwoofer rated wattage, but clipped and it may blow over a week of use. Make sense?

I wouldn't call the second one slightly clipped, it looks pretty damn bad.

Do the 6 12"s, it will easily do a 130, if you can a sony tunnel would be amazing! 8 12"s maybe.

Is it not made anymore? daaaamn! I don't know mate, I don't know...
