Hu Problems! Neeed Help Immediately

[mikel108 10+ year member]

Hey everyone,

Here's whats going on. I have an Alpine 7873 HU. I have the 2 fronts and 2 backs (6 1/2) wired directly to the HU. and everything is wired correctly. I just put it in a few weeks ago and all the wiring was done correctly. No heres the problem...today i was in my explorer taking out seats..hiding wiring under the carpet and what not....had the stereo on...and killed the battery...twice lol....after jumping my explorer the 2nd time...i went to go turn on the radio..and nothing...no sound coming at all. The HU is getting a signal..but no sound is coming out. Is it possible for me to have fried something in the HU? Whats the deal. Im lost....all the fuses seem to be okay.....confusion..someone please help me..any advice would be appreciated.

Thanks,

Mike

I'm pretty sure when you jump your car, it can spike the voltage. It even says to disconnect everything when doing it in my amp manual. You could have blown a fuse for the HU or fried something.
