I still have an alternator whine after trying a couple different amps and settings. I am running, currently, 130 amp alternator (factory alt was replaced with this a few months ago), Pioneer AVH-3700BHS (something like that), and a kenwood excelon 900.5 (something like that).
The battery is grounded in the factory location after I sanded down to bare metal (seems like a weird location) with larger than factory cable. The amp is grounded to the (-) battery terminal. Of course the power is run to the (+) battery terminal. The HU is grounded to a better location after being sanded down to bare metal. The 3 channel RCAs are run through the center console to the trunk next to the remote wire and backup camera wires. Speaker wires are run on the drive and passenger sides. Power wire from the amp to batter is less than 3' because the battery location is in the trunk, and same with the ground.
I am thinking the only other issues to check out are:
1. Wire from alt to battery (probably small and runs from atl to the trunk)
2. Engine to Chassis ground ( I dont know where that is)
Does anyone know where the engine ground is located in a 2009 Pontiac G5? I would like to try to upgrade the wiring 1st and then maybe check the wire from alt. to trunk. I only want to do it this way because the alt is hard to get to and will be a pain.
I have tried the ground loop isolators which helped with my PPI Phantom 900.5, but made it worse with the Kenwood Excelon.
