General Car Audio Discussion & QuestionsAll general car audio discussion goes here. Need help installing speakers, headunits, amps or electrical? Having problems with equipment? Have questions about a product, post here.
so i let someone else change my batt out and now my hu doesnt have power at all. thinking its dead. so can i just swap out units without changing the mounting brackets? its an older 9847. kinda like the alpines.
I wonder if the battery was connected backwards for a moment!
If it does nothing at all, before you change to a different head unit, I would check ALL the fuses in line with it. If there is a fuse for the stereo in your fuse panel check that one, now I am not familiar with Alpines, but if it has a fuse in the back or in the power wire behind it check that if needed as well. May just be a blown fuse. Most electronics like this have a reverse polarity diode that fully conducts & causes a direct short to purposely blow the fuse if connected backwards to the battery / power source to protect itself. I donít know how itís wired, but make sure all the wires are connected to the battery, etc.
yeah i checked all my fuses even the one on the hu itself, but didnt think of the one in my fuse panel. dont know if there is one, i'll check for sure. the hu is wired into the dash power. no leads going to the batt itself. rest of my dash lights work as normal.
