Looking for the location of the amp. I find the setup is strange, not sure that it is standard. The amp line from the receiver unit runs to the amp (somewhere) and powers two speakers in the galley/salon. The standard speaker line out from the receiver unit goes to a "Mute" switch on the dash. Unmuted the speakers in the stern have sound. In the mute position speakers in the forward statement have sound (but only those speakers). Anyone else have a setup like this?
