Re: Fuse blew on on cable coming from batter, replaced...
What size fuse are you using? You need a 30-
amp at least and #8 to #10 wire I would go
with the # 8 maybe lower, if it blows a fuwse
now you have a shorted output in your amp.
May This Will Help.
Yneed to confirm that you have sufficient power supply voltage. With your multimeter set to DC volts, the black meter probe on the ground terminal of the amp (not on the point where the ground wire connected to the vehicle) and the head unit on (so the amp will have remote voltage applied), touch the red probe alternately to the B+ and remote terminals of the amp. If the voltage is below ~11 volts, you need to check the wiring feeding whichever line is too low. If both the B+ and remote turn-on lines are low and your battery is fully charged, you may have a bad ground connection.
