hi all thanks for your help and support!!! I installed a nice flip down alpine cd player in place of my factory single disc. i wired everything up including running the wire to fuse box? so the amp will turn on. (been installing for years never had to do that before) I have good sound until i go past 15 on volume, speakers cut in and out (sounds like a cd skipping) just to give you an idea. Please help there has got to be another wire or something i need to ground. i cant jam in my manvan.
