Amplifier getting no power.

While getting the boat prepared for this summer, I turn key to listen to some music after I had charged the battery back up to do some work in the shop and nothing from the four speakers on tower. I check and there is no power to my amplifier (no green light) haha. Cabin speakers and head unit are powered and running powered seperately. I decided it could be a bad ground on amp ground wires so I did some work on that hooked them back up,still nothing.

Thought perhaps it was the amp. Tried a different one. Same result.

Any thoughts as to what the heck is going on?

It has got to be my battery I am guessing? I bought a Duralast Deep Cycle from Autozone last summer. Put battery Tenderer to bring it back to full charge before I was tinkering with it.

Think its the battery?

Did you test the battery with a volt meter? I would start with checking voltage across the amp power terminals with the volt meter. It will take all guessing out of the equation. Start with the meter's leads on the main B+ and B-, then move the B+ lead to the turn-on terminal. Should read battery voltage both times. Work back on which ever circuit is not reading battery voltage.

The head-unit and amp should be drawing from the same source.

Fuse on the power cable to the amp? I know that's a really simple idea, but stranger things have caused issues. Might also be fuses in the distribution block.

Thanks for quick replies. I will try the following. I am going to pick up some 30A fuses and test it out again.
If those fail I hope Autozone backs up their 12 month replacement gurantee.

Wasn't aware Autozone sold amps. That might be your problem.

Really sounds like your inline fuse.

Sys Control wire from headunit to Amp was the culprit. Got it fixed nearly right after I posted for help. I was overthinking it and checked all wires and found it pretty quick.
I guess I am too quick to panic and hit up Teamtalk!
Thanks for input from everyone!
