Re: Electrical problem in my Bro's car.
does this happen when the car is running or only when the engine is off?
if its an issue with the car running then its possible the stereo is hooked into a wrong feed. tell him to get a 10 ga wire fromt the battery to the head unit with a fuse directly after the battery. the switch wire or ignition wire doesnt matter it takes no current. also he needs to run a seperate heavy wire for the amp or amps with a fuse directly after the battery. also fit a heavy ground to each ie head unit and amp. ground the head unit via direct connection to the case. the thin stock ground isn't enough.
if its a matter where it happens with engine off then its a weak battery.
