"Well i was either thinking about the fosgate Hx2's or the kicker sl2L7 squares- both DVC. As for an amp i was planning on a fosgate 800.2 . are there any other amps for about $350 that i can get that would be better than the fosgate to power 2 12" subs w/DVC's?? "

Rockford uses the same model numbers in different series... so we have to know:

1) Sub - Power HX2 or Punch HX2? (Power being the better)
2) Amp - Power 800.2 or Punch 800.2? (Again, Power is the better)

Here's a rundown of the very basics on each:

Power HX2 12" Sub: Dual 2 Ohm coils, 1000W RMS/2000W Peak
Punch HX2 12" Sub: Dual 2 or 4 Ohm coils, 500W RMS/1000W Peak

Power 800.2 Amp: 200Wx2 @ 4 Ohms, 400Wx2 @ 2 Ohms, 800Wx1 bridged @ 4 Ohms, can accept 4 or 8 guage power wire
Punch 800.2 Amp: 200Wx2 @ 4 Ohms, 400Wx2 @ 2 Ohms, 800Wx1 bridged @ 4 Ohms, 8 guage wire only
