Report "I purchased the EQS746 and installed it right above my CD player in my car (older JVC model with 2 pairs of pre-outs), hooked up a pair of RCA cables from my deck to the MAIN IN on the eq, then hooked up 3 pairs of RCA cables from my amps (2 pairs from my 4-channel Alpine MFR-240 amp to FRONT IN and REAR IN, and 1 pair from my bridged 2-channel Rockford Fosgate P500.2 amp to SUB IN). I also tested and have 12.04V running directly to the eq (and blue lights are lit up, only when deck is turned on, so I know the remote switch is working too). I have tried multiple settings (low, medium, high for various gains). No noise comes out until I am nearly at MAX volume on my deck. I then unplug the RCA cables from the eq and run it straight to my deck, and there's PLENTY of power for both amps. I don't understand what is going wrong here. Please help"
