HI all,,,have a 240BR crownline with one fresh deep cycle battery. Radio/cassette and also have a six disk CD changer. When listening w/ ACC switch or slow idle the unit intermittenly shuts off then comes back on...only when a CD is on. When at higher RPM seems to stay running unless volume is turned up too loud. Is rather annoying and was wondering if it has happened to others and are there any fixes to be offered. AMP..?...fuses?,,,wiring...need two battery system?...Please advise...Thanks
