It's been some time since I've posted here so I'm sorry if this has recently been discussed. I've got a Kenwood HU and two amps. I've checked and relocated grounds but I still get the noise. The noise is a clicking or popping and it's only when the system is on and I activate another device in the car, such as the power seats - if I raise my seat and then let go of the button I get a quick click/pop - it's not alternator whine. Lower current circuits like the blinkers don't audibly affect it. Any ideas? Thanks.

You may need to isolate the power wire and get a cleaner power signal for your audio equipment. Use a relay and isolate the HU's power wires ( both IGN & constant ). Try this and see what happens. You can also check your RCA's for breaks or cracks at the plugin or along the cable.
