No sound from towers or in boats?

So everythin has been fine until today. The receiver turns on fine and appears normal. As does the 420 and each wet sounds amp. I checked all rca's also. No output whatsoever from any source. 1 of the tower and inboat outputs on the 420 were already bad so I'm thinking the others just bit the dust. It's from the 1st run of 420's. So basically everything is on but no sound

Reed,
With a female to female RCA barrel connector you can easily circumvent the EQ and verify you have a signal coming from the HU and fully functional amplifiers.
High impedance headphones with an RCA to 3.5mm adapter will allow you to safely check the EQ output. Or, with a multimeter you can check for an AC voltage at the output of the EQ.

Thanks. First thing I plan on doing is seeing if i get output directly from the head unit to a amps. I ordered a new 420 anyways bc the Mic cable broke off a while back too. Thanks Dave.

Reed,
I forgot to mention that the EQ may have an internal fuse in the corner on the board.

Thanks I'll check. I happen to have a pair of barrels and multi meter. Hopefully I can get it sorted tomorrow.

Everything works using just the head unit. Will check the fuse when I feel like taking the dash off.

make sure that the Eq is set to the correct input, that got me when i first installed my system.

I figured it out. I think it tr interior fuse, but the screws are rusted in. New ones on the way. If I gt it fixed I'll sell it for like 60$.
