I have a RF power 2FR1000bd pushing some older audiobahn subs (until my shivas get here on monday). When I have it turned up so its hitting hard, some notes will just kill the power to my subs, no bass. The amp stays on though, does not turn off. I turn my car off to cut power to the amp, then turn it back on and it works. But When I turn it back up and it hits a real deep note, it shuts back off. Anyone know what would cause this? Or is it just my amp cutting out for some reason?

impedance is dropping lower than what the amp can handle and is going into to protection.
by shutting the car off/on you are reseting the amp.

The subs are dual 6 ohm. I hooked one up parallel to run it at 3 ohms. It still cuts out when it hits powerful notes.

check the impedance of your + and - your conn to your amp with a multimeter.

what is that impedance?

^ Impedance is for AC.. not DC.

I think you've got a bad ground. Where have you got it grounded?

I'm banking on voltage drop. For a start I would clean up your battery connections, amp ground, and check the water level in your battery )if possible)

Yea, Im going to get some good connectors, put my circuit breaker in that i got today, and clean it all up. Im gunna put 4 gauge wires under my hood too. See if that helps anything.
