head unit = jvc kd-s570 (40 watt x 4)
amp = 500 watt jensen xa2125 (2ohm stable)
subs = 2 10'' rockford fosgate punch hx2 (DVC 4 ohm x 2)

i feel like maybe i should be getting more bass out of this...my 6x9s are hitting harder than the damn subs i've checked all the wiring (tightened doo-dads and whatknot). do i just need to buy a new head unit and a better amp? all replies are welcome:thumbup:
