did this a few weeks ago with the help of my buddy Greg (pentavolvo). it sounds great and is just what i needed to upgrade from the factory bose.haha. it's a little soft sided on the lows considering i had 2 15's in my old T/A, but it's balanced real well and looks pretty good, plus i paid next to nothing for all this.

Head unit: panasonic mp3/cd
fronts: Elemental Designs 6000 6.5" components
rears: MB Quart 6.5" coaxials
subs: 2 12" Elemental Designs 13ov.2s
box: subthump 1.0 ft. per chamber
amps: JBL BP1200.1 mono, Pioneer 4 channel (60 watts per speaker or so, they could take way more.hehe)
sound deadener: Elemental Designs eDead v.2
wiring: Knu Konceptz

need to let the subs break in a bit then turn the gains up and it should be pounding. had everything left over from my old car except for the deadener, 2 new subs and the subthump box. the best part was, i got the 2 new subs and the box for 220 bucks and the deadener was a few hundo. got 120 feet of it, but need more.hehe

 

Looks good, how do you like those subs? My 8 year old fahrenheits are starting to go, looking for something new.

 

they are **** and beer. they had a blowout on the silver coned version in dual 4 ohm, i got the pair brand new for 180 and the bucks was 50 bucks used, had to rewrap it in vinyl.

the subs can take a lot of power, a good 700-900 if you know what your doing. they get pretty loud and sound clean in a good setup.
