Hi guys. installed woofer and amp then unistalled it and headed off to pindi. no problems on the way. now on the way back road was empty so speed was high and didnt really care about potholes and bumps near haripur my speakers started goving gup gup and popping sounds only when passing uneven areas. Really dishearted and worried. it gives the sound like if you put a mobile near a computer external speaker and when a call is incoming it gives the popping sound. please help me and suggest whats wrong.
