Noise with Acceleration in Newly Installed Alpine Head Unit (1 Viewer)

[Cruiserhiggs]

I had this problem with my LX when I installed my head unit. I installed ground loop isolators and it solved my problem. They are cheap. I was able to retain my factory amp and upgrade my speakers. Sounds great and my factory sub even still works
