Hey guys, I was hoping someone could help me out with some stereo noise I am having in my tower speakers. I found tons of WW threads on the topic but most that I read were for alternator or engine noise. My problem is that I have a hiss from the tower speakers when the boat is on or off at zero volume. Here’s a few details
• Separate amps for sub, in boat, and tower
• WS420SQ
• All amps and EQ are grounded direct to the batteries.
• Boat has a stereo switch on the dash to supply power to the head unit. I did not change how the HU was hooked up from the factory and do not believe the ground is direct to the battery.
• Hiss increases with gain increase. Gain is at maybe 60%
• Tower speaker amp is an Exile XM30.2 driving 4- XM9
• Noise is only on the tower speakers
Thanks
