My set up is alpine radio to eqx from eqx it goes to two 2xs and from the two 2xs it goes to three amps. One amp is sub, other amp is Midbass, and last amp is tweeters and midrange.

When I connect my rcas to my eqx and have the outputs from the eqx disconnected and play something very low music comes out from my tweeters and midrange speakers. It does change volume with the radio knob or gains on the eqx. Second issues, with the outputs disconnected there is no hiss from speakers when I connect the outputs I get a hiss,all gains at lowest setting. The hiss doesn't get louder or lower with any gains or radio volume knob. No rcas are ran next to the power wire from the battery but the rcas are all ran with each other,going from eqx to the 2xs then to the amps. The rcas are close to the power connection and wire going to the eqx.
