Loud POP through speakers when car is turned on/off
Hi guys I have a 2007 c6 z06 1LT. Speakers are stock but I recently swapped in a Pioneer DEX-4100, RP3 GM11, and ground loop isolators.
Everything works great but when I turn the car on or off, I get a very loud POP in the speakers. Someone mentioned that it has to do with the Pioneer headunit powering on the the factory amps, but it doesn't seem like a common issue around here.

My 85 does this too. Swapped out to Camaro Bose with CD and when I shut the radio off, I get the pop. If I simply shut the car off with radio on, I don't

Mine did the same and went away with ground loop isolators. It happens with all Pioneer HU's with Bose Amps on speakers it seems.

Me and a whole bunch of other people. The issue has to do with the timing of the amp turning on/off. It could be a head unit issue, but I never heard of it being a Pioneer thing. Could also be amp issue, ground issue, connection issue,...etc. Hope the OP got it figured out.

I had this happen a few times when I replaced my stock 07 head unit with a stock 08 head unit. It would happen occasionally for a few months and then I haven't heard it again for at least 4 years.
