Bass passes through the seats whether they a folded down or not, thats not the problem, the issue here is if the wavelengths of the bass cancel each other out, of course i would suggest trying both and see what sounds best

Imagine that the vertical line on the left is the back of yourbsedan, the red line is the bass coming out of the sub, the yellow is it reflecting, what you want is these lines to overlap or the sound will cancel each other out reducing bass.

So the last image is your ideal scenario

Your ideal scenario

Cool, I will try (once I get a box for the IDQ12, it's going to take me some time though)

Thanks

So is this illustrating that the 'opening' for the sub is facing the back of the rear seat? Or should the opening face towards the back of the car? Apparently I'm directionally challenged. Thanks!

Yeah it took me a couple of seconds too, I usually do sections going the other way, but the image shows the sub facing towards the back of the car.

Thanks, I was planning on facing it that way. The angle of the sub box (I think) will fit up nicely against the angle of the backseat. Whoever sits there will get a back massage!

OH! And I just received an e-mail from Sonic saying free shipping on all orders over $20 between now and Friday the 17th (within the continental US)!

Received the new subwoofer box yesterday and WOW! It has a much smaller footprint than the ported box. Right now, the ported sub box is facing sideways, so based upon those previous graphs, I probably have it facing the worst possible direction. Live and learn. I'll take a side-by-side comparision picture this weekend and post it. If I like it, I'll end up getting more of my truck space back AND lose some weight. I'll try to remember to weigh the boxes without the speaker and see what the difference is. Probably just a couple of pounds at most.

This past weekend, I pulled the Alpine 10" Type-R sub from the larger, ported box and installed it in the smaller sealed box. I am able to re-position the smaller box so that it is facing the rear of the car and the back of the box is snugged up against the back of the rear seats. I had to elevate the box about 3 inches so that the back would fit against the rear seats as there is an angled piece of hard foam (kind of hidden by the trunk carpet) at the base of the back seats in the trunk. To keep it from sliding around, I picked up some ultra-heavy duty Velcro and used it to help secure the sub box from shifting around.

Then I spent some time re-tuning the amps and new HU. WOW!!! What a difference! I'm feeling more of a 'punch' with the new sealed box, plus now it is oriented the right way AND it takes up about 1/2 the space of the ported box. It's a win-win! The ported box was facing side-to-side, not the best way, but gave me more trunk space. I have pictures, just haven't pulled them off the camera yet. I'll try to do that in the next couple of days. Kind of crazy right now with the holiday's and all that.
