Well my new friend.

It is the amp.

You are correct. I do not have an extra one lying around.

I hooked the speakers directly up to the Sony HU as you suggested and they work perfect. The cutting out is completely gone.

I guess this is the first Bad Stinger Amp. It's brand new.

 

I would hook up a speaker directly to the hu to see if it’s the hu or amp.

 

eggwhite suggested the same thing.

Took his advice and did just that. See post above.

Looks to be the amp causing all the issues.

 

Well I’m happy you got it sorted out. Sucks you had to go through all that. When you get the new one go ahead and keep that ground to the battery. That is the best method. Good luck with a replacement amp.

 

I am thinking JL Audio for my build which is coming up soon.

Do you know if anyone is running a non marine grade JL amp?

 

I don’t.

Also don’t sleep on the MMats 4110 amp. That’s what I am running and it is serving me well.

 

Good suggestion. I have seen that amp in the threads.

Also, will make sure to keep ground to negative battery terminal.

 

What did you do with the green parking brake wire?

 

Green parking brake wire out of the Sony HU?

I don't remember that one honestly.

 

I think I remember reading somewhere where it's supposed to be grounded. Not sure if that would be the root of your issue or not. I wouldn't be real quick to rule the amp as the culprit. Could be a number of things. I'd try changing the RCA's to a known good one. It's not impossible that the amp could be bad but highly unlikely.
