damn, i dont know the source, but i think crutchfield carries them, i think. but these are custom made enclosers that fit under the backseats. when you are talking 10 or 12's. that is not enough info. some subs are design for compact boxes some are not. i have a 10" solobaric (spelling?) that only requires .66 cubic feet of space. (airtight) that is a tiny box. i have it in the back of my ZR2 S10. i bet the factory amp just drives the sub. mounting the amps will be a
bitC!+!. under the seats are your only options. and as far as wiring, i would go with a harness that snaps into the factory wiring. except the amps wire directly to a 12+. good luck, now that i am starting to get older/wiser, personally i will get the best factory stereo available and leave it at that. i have had enough with electrical problems. that and i have permanently damaged my left ear. (loud stereos, loud sportbikes, and loud guns)
