I have the Marine 4 Channel AMP and nothing is coming out of the back 4 speakers. Not sure if there is a fuse blown or what. The front speakers are no where near as loud as they should be. Looking for things to trouble shoot.
No fuses for front or rear, just the entire amp. If the amp has all 4 RCA inputs populated, check the FADE in the head unit. Find the FRONT L&R and the REAR L&R RCA inputs and swap front to rear. Since the fronts atleast produce some sounds, lest see if the rear give some sound now with the front RCA. If the note the speaker connections, you can swap the rear speaker leads to the front chnls and so forth.
I have fade in neutral but moved back and forth and same. Just sound from front. I will try to change front and back inputs/channels but what will that prove?
