So I just tried to install my new clarion equalizer and it turns on and everything, but fails to control the volume control and equalizer setting. I will explain my wiring, and hopefully someone may have a solution? Right now my deck is a sony cdx-gt56ui with only one pair of RCA outs on the back. I hooked the equalizers main auxiliary in from the head unit's one pair, and that didn't work, so i eventually just tried every single input on the back of the equalizer (sub, main, aux, front, rear) and none of them worked still. For my power, ground, and remote wiring: I have a solid no spliced wire coming straight from the battery for the 12v connection. my ground is spliced with my head units ground. and my remote is spliced with my sub amplifier remote. The only conclusion I could come up with is that my deck's RCA's are just refusing to work with the EQ because its not a high quality deck, but thats all I could come up with. Your help is appreciated, thanks.
