Hi guys. New here. Just picked up a 2006 sunscape 247 that will be a project for us this winter as it has no ballast or pumps or anything and we like to wakesurf, past boats were 2002 nautique 210 and 2006 Mastercraft x2. Boat has a tower and a decent stereo, just replaced head unit with a fusion ms-ra70 to upgrade to Bluetooth and this radio as well as the past unit has feedback in the speakers that are running off one of the amps.
ive cleaned all grounds at battery, at boat, and when i disconnect alternator it goes away when running, only happens when boat is running.
im seeing a few options on noise filters. It before I pull trigger wondering if anyone had this issue and if they were able to track it down or what products they used to fix it.
thanks for your help!
