i have a cheap sony $90 headunit and when im listening to music if i go over a certiain volume the system shuts off and restarts. idk why or what it is my guess would be a safty feature but its like i cannt llisten to my fav songs loud without it shuting off. im not sure if this is a wiring issue becouse its wired up right and before i put the headunit in the (casset player) would go as loud as u want it? any suggentions are worth trying pleasae let me know
