Which way do you have your subwoofers facing? Towards the seats. Facing up. Or facing the hatch? Trying to get the best sound. Trying to see how other hatch owners got there set up.
For people with subwoofers on a hatchback

You really think so? I've been searching this all afternoon most people say towards the hatch. I haven't tried them facing up. I've also read that if you have ur rear seats folded down they sound better.

Toward the Hatch will increase car vibration (for no beneficial reason), and make you sound like an idiot.
The most efficient way to disperse the sound would be for it to face up.

If you want sound quality then you need to face the subs and port upwards, If you want SPL or sheer loudness then you want to face them to the rear approximately the ports width from the hatch wall... So for example if your port is 5" wide and 10" tall place the enclosure 5" from the hatch wall. This will create more rattle but also will create a wall for the sub woofer and ports pressure to "load" thus allowing for more bass you feel rather than just hear. The distance will be optimal so the waves will not cancel and you will feel them physically more. If your port is extremely thin such as 1" then place the box about 5" from the wall. If the box is sealed then placement distance doesn't matter, rear facing for SPL and up for SQ. If you lower your seats you do gain a great deal of SPL.

Don't ever face them completely forward... It KILLS SQ and SPL. sounds like garbage.
unless they are sealed as wall.

Ive ran subs walled, forward, up, down, side, back, port side and sub up, port forward and sub back... Just every single way possible. When I had an sa 8v2 in my sonic I had time to play with placement for the most output. Best results were 5" from the back wall, all rear facing.

As this image shows, example is the woofer and port (sound waves) firing to the left of the image and hitting said wall, once they hit the wall (hatch) they will travel back into the cab. You want them to hit the hatch and travel back so the waves are in sync and not canceling one another. which is 5" from the wall.

I have mine facing towards the hatch.
When I have them facing UP there isn't as much bass resonance, and I don't hear some bass notes from certain songs that are there when the subs are facing the rear. Keep in mind this is a ported enclosure and there is a port on both sides (not visible).
There was no rattle for me before or after I added sound proofing, but I went ahead and did it anyway. I'm convinced it sounds better with it. I've stood outside the car and it still sounds good. No rattles nor is it boomy. Sit inside, close the door and it sounds great.

If your ports are side firing it shouldnt make any noticeable difference facing the subs up or rear. Your Ports are still loading pressure to the sides regardless. In a ported enclosure port direction is 99% of the sound.

Yeah... except it does make a difference for me. Not significant, but definitely noticeable.

I've been thinking about sound proofing my car. Is it hard/expensive?

I don't know about expensive, but it is easy. All 5 of my doors are done. Get a rubber roller and look at some YouTube videos. Should be fun.

Mister, could you tell me the ports width, height, and approx. length? and its distance from being flush with a wall? You don't have to but I study these kinds of things... If I can take what you told me and study on the ports placements it may provide valuable information for many sonic owners intending on doing a subwoofer.
Also you said a port on both sides?

Turbo sonic, look at your local lowes or home depot for "peel and seal aluminum flashing" It's plenty to deaden our sonics on a budget. And it works fantastic.

Quinton, this is a prefabricated JL Audio box, so I don't have all the info. Especially the port length since it goes through a chamber. The model of my dual 8" sub box is CP208LG-W3v3. And yes, there is a port on both sides. This is essentially two of JL's MicroSubs fused together.
There is about a 2 inch gap between the wall on both sides of the subwoofer enclosure to the wall.
