Question about MA Audio HK401SX Car Audio Amplifier
You have a bad ground in most cases.
Because of this the amp tries to pull ground from the RCAs which are connected to your grounded headunit chasis.
To make a solid amp ground. Find a piece of metal (not the back deck), scrape off the paint and then use 2-3 self tapping screws with washers to keep the ground from moving.
And of course plz don't forget to rate me ;)
