The stereo of my car is showing some problem and after some time it will produce some heat, now i think this may happen some problem in my car. I can't understand should i replace that stereo or to remove the whole system from my car.
Thanks for commenting,Before i have trouble encountered regarding the signal light and hazard problem the fuse always busted.due to car stereo overheating.out of relation on the problem but because of inside passenger fuse box or smart junction box they are connecting in one electronic box that's why it affected.i advice that replace new one or remove it from the system.
