Amp and battery wiring diagram

[Brichter14]

I have been having amp troubles so i am curious if my wiring is wrong. This is what it looks like

Since your battery will already be a direct ground to the motor I would run your negatives to one battery. This battery would be the same source for your power. The way you have it now the system can draw off either battery. I like to draw power from a dedicated source and have the other for starting etc.

What problems are you having? Are they not turning on? The wiring you have is not "wrong," however, I would prefer my amps to be directly connected to one battery. The other battery could then be used for a "starting" battery.

One amp goes into protect when other accessories are on like perfect pass and lights. There is a grounding problem i think.

So ground the amps to battery 2 and also take 12v from battery 2? Should i leave everything else on the common post of the perko?

That is how mine is set up. I'm not sure why your amps go into protect mode when you turn on your lights and perfect pass. Those don't require too much power. Are your batteries fully charged? Some amps go into protect mode with low voltage. If your batteries are low, those extra accessories might bring the voltage low enough to shut down the amps.

Funny thing is it isnt both amps going protect. It was one amp. The other was fine. And it wasnt a bad amp either, i got another one different brand and everything and it does the same thing.

This is what I would try... not all at once but one at a time.
1. Make sure batteries are fully charged. Even if they read 12v they can still be lacking charge.
2. Make sure remote wire is reading 12v when accessories are on.
3. disconnect speaker wires and use an ohm meter to make sure your speakers are measuring the proper impedance. Verify there isnt a short. (Low impedence) also verify that your wiring doesnt go below the impedence specified by the amp
4. Connect ground and 12v directly to battery to eliminate possibility of power connections being bad.
5. Try turning on amp without rca's connected.

H2 thanks for all the help, i have tried all of those things already in the past. Today I decided to change the power source for my headunit from the wiring harness to constant power and ground running directly to the AMPs power source. This fixed the problem! I must have had a bad ground to the headunit, or it created some grounding loop. Anyways thanks for the help!
