so i have an AVH-P6800DVD and a metra wiring harness made for the RF HU replacement after connecting all wires properly i have a terrible alternator whine. i have since spent the last 2 hours eliminating any ground loops and trying to find a good ground to stop this wretched sound. i am no dummy to stereo installs but this one has me dumbfounded:bangit:
is there a trick with the RF amp that i am not seeing or a good ground that is reliable. it would be alot easier if metras [email protected] install kit wouldve been metal so it would ground the casing to the same place as the stock unit. Please help.
