you sure it's not your cell phone? JK... what do you mean ringing?

like this weird noise coming from the speakers when the radio is on and when i press on the gas it gets louder..i know its a grounding issue but i dont know where the usual bad ground is for the stock MSP kenwood setup

yes, it's probably engine noise entering the system.....mazda has used cheap cable to wire the sub amp and in my car at least, the power wire and rca patch cables were strapped/run together....to fix...buy better cables and run power and audio cables on opposite sides of the vehicle..not together.

i already got better wires and istalled my subs and wired them on the other side of the car...so what else could it be

then it's a matter of trouble shooting.....could be anything.....could be the ground itself, the rca's and so on.....no easy fix unfortunately.....just start at the front with each component and work ure way back.....a bit of work but worth it in the end.

oh, and just a thought....if ure running ure rca's down the passenger side....make sure they don't run directly around or over the ecu.....that can be a source as well.....
