Very true, but I have heard stereo installs with two 12" JL W1's in an S-10 and it was loud as hell. There has got to be a solution. I know I was able to fit an L7 Solobaric in my S-10. I could only fit one while the entire box took up the entire rear part behind my seats. I didnt get the bass that I wanted out of it. It was one long ported box. lol

I put a pair of SA-8's under the rear seats in my dad's '03 Silverado & they get damn loud. SA-8's are gonna have more output than almost any 12'' you can fit under there & probably most 10's too.

Well, his truck is 300 miles away in Oklahoma so I cant get any pics. But I know what subwoofer box Im going with and it has the mounting depth listed so thats what I am going off of.
As for the 8" sub idea. I know there are some 8's out there that get loud, but I simply wont have the time or the resources around to build a box for him. Im gonna have to go with the box from subthump.com

polk MM1040 10" sub has low mounting depth and needs .66 cubic foot sealed. i send mine 435-450watts each and they are fine with it. doesnt get crazy loud sealed, but the SQ is great, but ur limited so limited choices

this sub would destroy those rex's, the new re's are not the same quality as the old ones. amazing sub this is, only 3.5 mounting depth

Also, I got to thinking today and I am entertaining the idea of going with 4 8" subwoofers. RE Audio only makes one 8" sub and thats the RE RE series. They dont list any specifications on airspace requirements so Im not sure if .70 cu. feet of airspace would be enough for two 8's on each side. Thats a total of 1.40 cu ft total for both sides.
The RE RE sub's efficiency is pretty low at 81.2dB.
I do like the T3 10" Option you mentioned above as it has an effeciency of 87.97dB and the fact that for a sealed enclosure, they recommend .7 cu ft of displacement, which is exactly what the subthump box has. I will have to take into consideration of the subwoofer displacement of .14 cu ft so I would end up with a displacement of .56 cu ft, which is reasonable.
The DC Audio Level 2 Subwoofer looks nice. There isnt much info on it. Any idea on how much airspace it requires and the mounting depth? The maximum mounting depth I have is 5.5" for a 10" sub. It also doesnt list the efficiency rating, but after reading, I guess it doesnt really matter.
I really like the Elemental Designs 11Kv.2 sub. The ideal displacement is a mere .5 cu ft, which is perfect. Minus the sub displacement of .05 cu ft and I end up with .65 cu ft. That gives me some room to add some polyfill. Effeciency rating of 87.1 dB is great. Looks like it performs exceptionally well in a sealed enclosure. Not much less than if it were in a vented enclosure. 300 watts of power handling sounds good especially with the effeciency rating.
As for the PG RSD10, Im not to sure on these subs. I know they made a couple good amplifier lines like the Tantrum, which I currently use 2 and looking for a third (If anyone has a 600.4 or a 500.2 Tantrum for sale, please let me know.) I am also looking to power his stereo with Tantrums. I just love their amps. The power handling for this sub is 500 watts rms, but the efficency rating is rather low at 84 dB.
The Stereo Integrity's BM mkIII looks like a great match if I want to squeeze in a 12" sub. 3.2-3.4" mounting depth is perfect and 450 watts of power handling is a good match. I am also drawn to the XBL^2 motor. They recommend a .5 cu ft enclosure. My enclosure will have .7 cu ft.They say that .5 is optimal. Going less with lower the low frequency output and a larger box would reduce the power handling, but I dont think a .2 cu ft (im guessing on the driver displacement) difference will be all that noticable. Total volume after subwoofer displacement will be .65 cu ft so it wont be much of any difference at all. Im liking this subwoofer option. It matches my box, power handling, and the fact that I can fit 12" subs. Im just curious to how it will perform compared to the other subs you listed.
I know efficiency ratings are not meant to soley base a decision, but I like high efficency subs, especially when I am dealing with a small sealed enclosure. But I have also read that for small sealed car audio enclosures, the lower the efficiency rating, the higher the output. Thats a bit hard to believe, but maybe someone can confirm that for me. Maybe its a misconception about higher efficiency ratings = more output. I got this info from here. http://stereointegrity.com/docs/Efficiency.pdf Pretty interesting stuff. From what they are saying is that if you are using a small sealed enclosure, go with a lower efficency woofer, but if you step up to a larger box, say 3 cu ft, then the higher efficiency subwoofer will have more output.
As you said above, they arent the same as they use to be. Did RE Audio screw up their design and make them worse or did they do something drastically different to make them not such a great choice?
Does anyone have any good recommendations for an 8" subwoofer? I have to do this on a budget. I know there are alot of great 8" subs out there. I have just been out of the car audio thing for a while. The amount of airpspace for the subthump box is .70 ci ft per side. Is that enough for 2 8" subs on each side? Is that enough airspace for any of the 10's you mentioned?
Im looking for about a 60/40 on SPL/SQ. He wants them to sound good. He also says he doesnt want anything to be super loud, but he is 19 years old and we all know how that goes. You get a stereo and after a while, you think, man, I wish this was louder, so I am just planning for the future. I am wanting to set him up with a very loud set of Subs that sound great. But of course, thats what everyone wants, right? lol
Sorry for the rambling guys. I like to type out loud, plus I want to document my findings for when I make my decision.

personally this one will probably be ur best bet. its going to have the best sq and just as much output as the others imo. problem 1 is that they are expensive, problem 2 is, best i can tell anyways, u cant buy them right now. it just says they will be on sale when parts are available, maybe i missed it tho
sundown sa 8s are probably ur best bet for spl 8" subs, but not sure how they are gonna be sealed. custom ported box for these and he will have the spl he wants as long as he has the amp for them. they only need like .6 cubic foot ported, but they all gonna want some power however many u get. i thought u werent going to build a custom box? he is far away but get him to measure everything and build it, then he can drive to ya and test fit it, if it dont work, make the corrections, im sure he will like it more than 10s sealed if he wants some good thump

Nah, my box building days are over. I have built so many boxes, roughly 30 of them, and Im pretty burnt out on them. Its just so much easier to get one from subthump.com. I take it that you have never seen one of their boxes personally. They are the best prefabbed boxes I have ever seen. I personally dont buy prefab boxes, but subthump boxes are the only ones I will get. They are notorious for squeezing out every single bit of airspace as possible. If I start building, the poor guy is going to end up loosing 6 clicks on his seat. LOL Thats just how I get. I start small and end up big.
As for power sources. Im going to match him up with an amplifier that will suit whichever subwoofer option we go. That ***** that the Stereo Integrity's are going to be a bit expensive. The timeline doesnt bother me so much since we are piecing everything together one at a time, into two phases. Front stage as one of the stages and then his bass as another stage. Havent figured out which phase we will do first.
As for amps, Im going to try to find another PG Tantrum 1200.1 like I have in my truck. If not, there are other options that will be fine. Just a matter of finding some subs that will slam and impress his college friends, yet sound much better than his friends' vehicle installs too. You know the type, "Oh man, my $3000 JL Audio stereo system is the best ever!" kinda crap. Im trying to show him what audiophile means and that there are better brands out there than the ones you can see on display at Cartoys or Best Buy.
And this will have to be a sealed enclosure. I dont even want to begin to even try to build a truck style box all ported. I did that in my S-10 with a Kicker Solobaric L7. I had no legroom. I ditched that box pretty quick, but luckily enough, I traded my S-10 in for a Grand Am GT. Now the stereo I put in that was the best sounding stereo I have ever had, and it was in a ported box with the new Alpine Type R's tuned to 31hz and I gave it like, 3 1/2 cubic feet after port and speaker displacement. Its that stereo that is going to make me trade my 2008 Crew Cab Sierra in for the new Camaro or Corvette. I miss that sound
Doesnt Incriminator Audio make some bad *** 8" subs?

I was checking out the T3 600 10" subs as mentioned, and I liked what I saw, but then I noticed that they only offer one voicecoil configuration, Dual 4 ohm, which would mean I would end up with a 4 ohm or a 1 ohm load on the amp.
I would need a Dual 2 ohm subwoofer so I can run 2 subs at 2 ohms.
My only other option is to cross this off my list or run an amp at 1 ohm. He can't really afford an amp to run 1200 watts at 4 ohms and I don't like to run amp at 1 ohm. I have always been that way. Its going to be behind the seats or under the seat and I feel it will get too hot and heat destroys amps. I like to run sub amps at 2 ohms and front and rear stage amps at 4 ohms although I just added my rear set of Focal K2P's to my Phoenix Gold Tantrum 500.2 with my Focal Utopia compenents so that amp is running at 2 ohms. My 17 year old Clarion 4 channel amp died on me and it was powering my Focal Utopia's. I had channels 1 and 2 bridged for the drivers side and channels 3 and 4 bridged for my passenger side. I must say. Im beyond impressed with the TPP.2 Tantrum. I have the gain barely an 1/8th of the way up.
So whatcha guys think? Run 4 8" subs sealed or run 2 10" subs or 2 12" shallow mount subs?
Currently, from the advice I have received from you guys, my First Option is 4 8" subs and my second option is 2 10" subs (DC Level 2, RE SR, and RE SE.)
remember, im looking for a blend of SQ and SPL, so the subs have to work good sealed with. 7 cu ft of airspace and 5.5" of mounting depth. I could probably get another half inch of mounting depth if I ran with 8's, pending on a reply back from Subthump.com
Its too bad he doesn't have a car. Id put 2 12" RE SE's in a ported box or the new Type R's. Its tough with the newer body style regular cab Silverado's. That's why im having so much trouble being indecicive. So I apologize for dragging this out
