put in my new HU and a small amp. no problems with either install. blew the 5a fuse that controls the dash lights. replaced it with a 5, 7.5 and 10 and they all blew. Put a 15 in and it stayed but the dash lights still dont light, then my headlights wouldnt go off when turned on. Pulled the (-) battery cable and got the headlights working correctly but still no dash. Any suggestions? Could it be something with the stereo? I followed the instructions correctly and it all works great. I stuck and getting pissed!!!
