baaudio Posted June 13, 2012 Report Share Posted June 13, 2012 Basically as title states.... I've just had my new Kenwood screen suffer this fate. I was doing some mods to my enclosure and when I turned the headunit on.... BAM!! Engine whine like crazy! This will be my third Kenwood screen in about a year that has suffered this fate, fortunately warranty is pretty easy for me. But it seems so many failures would raise a red flag as to me doing something wrong. Help me out guys cuz I would really like to prevent this issue if possible Quote Team NWSPL baaudio Build Log 2001 GMC Sierra walkthrough 4 Mechman Elite 370s, 10 AGM batteries, 3 Crossfire XS v2 18s, Crossfire 8k Link to comment Share on other sites More sharing options...
ricksi30 Posted June 13, 2012 Report Share Posted June 13, 2012 Hot swapping amps. It is more common in pioneers, but I have heard that some kenwoods can also have this problem.

baaudio Posted June 13, 2012 Author Report Share Posted June 13, 2012 I didn't swap amps, although I did disconnect my rcas to reroute them... The amps were powered up but not playing. I've been searching like crazy, and just read that plugging in rcas while amp is on can cause it. Dammit. That makes since with the other two also....

ricksi30 Posted June 13, 2012 Report Share Posted June 13, 2012 That is what will cause it.

ricksi30 Posted June 13, 2012 Report Share Posted June 13, 2012 Ground your rcas and that should fix it.

baaudio Posted June 13, 2012 Author Report Share Posted June 13, 2012 Meh I'll have a warranty swap tomorrow. But it makes sense now how it's happened so many times.

SmallTruk Posted June 13, 2012 Report Share Posted June 13, 2012 He meant hot swapping RCAs. When you say kenwood screen are you referring to a HU? Quote Link to comment Share on other sites More sharing options...
ricksi30 Posted June 13, 2012 Report Share Posted June 13, 2012 Yeah just make sure that whenever you touch wiring, or fuses that you disconnect your negative battery cable. Sorry for the double posts, I don't see an edit option on the mobile skin.
