Ah ha, I guess that would be the problem. Since installing the player in my new car it tends to shut off quite frequently do to low power. Im thinking I need a new battery. What confuses me though is it hasnt shut off when my amp is really sucking power(ie headlights dimming do to bass hits). Im kinda baffled it only seems to turn off when Im sitting still in the heat of the day with the A/C on. Im thinking it may have to do with the radiator fan turning on because it happens when Im in traffic mainly. Oh well I guess ill get a new battery and see if that fixes the issue.
