I was going to ask why one would pick sealed over ported and googled it and answered my own question. :) Heres what I found:

I got this from Image dynamics forum when I was asking for an advice between sealed or ported in my sedan:
1) when ever you place a sub in a box ( ported or sealed ) in the trunk of a car you will have to deal with the transfer function of the volume of air in that trunk. Simply put larger the trunk thicker and heavy the lower octaves sound plus the notes feel lethargic. 2) A direct input to the cars interior is the best approach for best overall SQ but not necessarily what some people want in the bass tone ( to flat sounding to their ears ) D.

Good find. For the kind of music I listen to, I think the sealed box will sound better. We'll shall soon see...err....hear!

I have a pair of Kicker 12's and have them facing up towards the 6x9 openings, (6x9's removed ) maybe your outcomes will be different since your trunks are deadened but mine sounded okay at first, now i'm ready to face the box a diff direction. I think mine sounded best with the "ass" end of the box facing the rear seats and the subs towards the back of the trunk. I'm ready to also try a ported box, right now i have them in a 1.0 cubic foot per chamber sealed box. My Hifonics amp is fairly new so i haven't unleashed it on the subs yet, but i see some Type R 12's in my near future, with a ported box.
Oooo and i have a 4 day weekend comming up, so all i need is a saw, and i'm relocating my amps so i can play with the box placement.

I tend to disagree with 2) - i have tried various ways and in a sedan as close to the opening of the trunk face rear is the best in most situation, least cancellation of bass. |

Maybe they mean that if you have a ported box and the port opens to the cabin, like I've seen in some applications. (I know and I remember this was SQcomp's plans long time ago) To me, it's all about learning and trying new things! We'll see how it works for Herb? maybe he would need to fold down one of his seats!

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 |

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!

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.

Thanks Derick! Same to my friend! And to your family.
On a slightly different note (no pun intended) I noticed this morning on the drive in to work (still dark out) that my headlights were pulsing in time to the music. First time I've seen this happen! I didn't think the volume was THAT loud! I was at a stop light waiting for it to change when I saw the headlights pulsing. This one particular music track has a TON of deep bass and it was definitely working both the amp and the subwoofer. I backed the volume down a few clicks and that reduced the pulsing effect. Obviously I'm not going to notice this during the daytime. Are there any inexpensive mods that I can do to eliminate the pulsing of the headlights? Besides turning down the volume?

BIG 3
Let me check and I'll see if I can get a set of cables ready to install and how much they cost, and if you want them I'll send them to you. D.
