I am running a Kicker KX650.4 amp. Its 4/3/2 channel and I am running it as 2 channel. I have one sub running to the amp1 channel and one sub running to the amp2 channel. I am using the high level signal inputs with the rca dummp plugs in the amp 2 input (per the instruction manual). I am using both sets of high level inputs (1 for amp1 and 1 for amp2). Each channel requires 2 speaker connections. (high level for amp1 and amp2 require connections to both the R and L speakers). I connected the high level input wiring harness' together (i am only using the rear speakers as signal inputs) so the L from amp1 and amp2 are connected to the same rear hatch speaker. The subs I am using are 12" kicker L5's dual 4ohm coils. When I turn the system on, there is almost no sound coming from the subwoofers. The indicator lights are green, so there shouldnt be a problem. What could the problem be. I wired the subs like the instructions said (connect one of the - to one of the +, then connect the other coil to the amp).
There is almost no sound coming from the sub. Bad ground maybe?
