Does anyone know the best way to put two 12" JL subs under a seat? I have an '00 Jeep Grand Cherokee and I have a feeling I'm going to have to make two custom fiberglass boxes...I've searched for custom boxes but they don't seem to exist. Also, if anyone else has any other ideas on how to accommodate two subs somewhere else than my trunk (I have 3 JLs back there) or under the back seat, it would be greatly appreciated. Thanks.
EDIT: I can also reverse it (put the three 8" subs under the seat and the 12s in the trunk) if that makes the process easier...

I'm just now getting back into car audio and need some assistance in finding my ideal sub...
1- 15" sub (1 only)
2- respectable SPL from sealed fiberglass box.
3- performs well with minimal airspace. (maybe 3ft^3?)
4- handle anything below 2500 watt RMS. (closer to 2500 the better)
I know I need more space and I know ported = godlike qualities, but I'm experimenting with fiberglass and the location I've chosen is relatively small.
The amp I have is an Alphasonic PMA1200DA. Just bought it today (used) for $150. It works and I believe is the Craigslist deal of the year haha!
Anyway, thanks in advance
And try not to flame me too much...
So I've looked at many-a-build log and have decided to go with the hang the amp-rack from underneath the rear deck design. [The sides of the trunk aren't really an option. The floor of the trunk is to be kept clean and open (for ski/snowboard season). Not enough room under the seats in the cab. And I didn't like the idea of mounting amps to the back of the rear fold-down seats. Which left the rear deck. Upside down I'm far to weary of to attempt.]
So! Below is the rough design drawing of what I'm looking to do. While I'm relatively happy with the design as it is (though feedback is appreciated), one particular sticking point for me is the rack slide hardware. I can easily find plenty of cabinet slider racks to accomodate the weight & size of the equipment. This is an acceptable solution, however I can see the point of difficulty being making any adjustments, and even connections on the backs of the amplifiers.
What I would really like to have are, sort of 2 stage slides. Stage one being that it simply slides out. Once the maximum is reached, the slide becomes a hindge, allowing the entire amplifier rack to fold downward, leaving the control bits of the amplifier facing upward, allowing for easy adjustment, maintenance, plugging/unplugging wires, etc... Once we're done, filp the rack back in line with the slide, push it back in, and lock it. I know I've used cabinets or whatnot that have used this type of slide rack hardware, but for the life of me, I have no idea what something like that would be called or where to look for one. If anyone knows what I'm talking about, please, let me know.
Amp rack in its 'locked' state. Though not illustrated, locking mechanism would be either
A) two simple security bolts on either side locking into the two frame MDF pieces (actually these may be 2x4's instead of MDF). or
B) The bottom support frame MDF piece (the piece connecting the left and right side of the rack frame, underneath the actual movable portion) would be cut back slightly at the front, with a hindged flap piece at the very front that would fold up to 'lock' the rack in place... this would allow for a carpeted 'cover' door for the rack, improving looks, that also serves as the locking mechanism ensuring everything stays in place while the vehichle is in motion.
Amp rack in its 'extended' state. Or per above, the end of the first stage of the slide.
Though not drawn, the 2nd stage of the ideal rack would be after this point, where the entire front of the rack folds down while the rear is hindged, by this magical slide, at the frame.
Anyway, that's my spiel. Any feedback is appreciated and again, if anyone knows where I can find my magical 2-stage slide hardware, I would praise and sing your glory for days to come.

I am somewhat lazy and dont have access to many tools, so I went out and bought a cheap box made out of ~5/8 mdf. I didnt realize how important box strength is. Some people say you can strengthen the box by adding dowels, or by coating the inside with polyester resin. one guy said he painted the inside with wood glue. do any of these work or are they all bull? if they do work, do they do enough to be worth the cost/hassle? are there any other suggestions for a quick fix? its a 10" sealed .70cf box, will run a 300wrms sub.
thanks for helping the newb here
