OK, so I need some help. I just got a JVC KW-AVX710 head unit for my Santa Fe. Not knowing that it only has one set of outputs for RCA cables. I am currently running 2 Kicker amps (a zx1500.1 for my subs and a zx200.2 for my door speakers). These amps both have inputs and outputs on them. So as of now I have the RCA's running from the head unit back to the 1500.1 amp, and then I linked the amps together with another RCA. Now I am getting a whining noise coming through my door speakers and door speakers only, nothing through my subs. Also when I accelerate on the gas it gets louder. Before I had a Jensen VM9312HD head unit and had 2 sets of out puts, no noise. Is there something that I am missing or need to buy to get this noise to go away?
