I moved some items from my Jeep Grand Cherokee to my G6 and did a fresh install in the G6. The amplifiers are the same amps I had in the Jeep. The RF Prime 1200-D and the US Acoustics Barbara Ann. What I did was insert the RF 3Sixty.3 into the system and left out the Stinger 10F Hybrid cap. The head Unit is also the same one I had in the Jeep The Kenwood eXcelon X998.
I am fully active. The G6 has RAP (retained accessory power) and I am using an Axxcess wire harness to retain all of the factory options like warning chimes and the RAP. The Barbara Ann had to be sent off for repair so while it was gone I used a 4 channel amp of my sisters. It is a Quantum Audio Solar series amp. It worked with no issues, was loud and clear. When I got the US Acoustics back I swapped the amplifiers. I reset all levels in the DSP and set the gains.
Now when I shut the car off with the key and the radio continues to play as it should, I open the drivers door which cuts power to the radio as it should and a split second later POP!! Through the mids and highs only. It also pops if I shut the head unit off. I have checked all grounds and they are tight. I checked all power cables and they are tight. The remote wire goes from the head unit to the DSP remote in and from the remote out on the DSP to both amps. I tried different routing of the remote wire such as directly to the 4 channel amp and no change, still get the pop. Again, the Quantum Audio amp did not pop at all.
The only thing I haven't tried yet is putting the Cap back in the signal chain. I know this amplifier did not pop when the Cap was in the system... the system was dead quiet. Anyone know anything else I can try to get this system to stop popping when I turn the key off?
