I finally got everything installed and it sounds great. Then I did the park brake bypass for my dvd player and now my subs are just making a loud hum. I have checked my ground and do not see any issues. Any suggestions?
From your description, it sounds like there was no hum prior to the DVD bypass you put in. If this is the case, if you remove it, does the hum go away again?
When I remove the relay the hum is still there. I looked to see if anything grounded when I pushed the head unit back in place but cannot find anything.
