Would putting in a capacitor help? The boat uses an alternator to charge two batteries (one for starting and the other for the radio)

severancej, Thanks for the help (along witht the others). I hooked the multimeter to the pos and neg and it is reading 12 and down to 11 (occasionaly droping into the high 10s). Is there something I can do? Also the Amp gets really hot (Alpine monoblock MR 1000). I have to have it loud to compensate for wind noise while driving (the system is in my boat).

The gage of the wire is 4 gage and chevyBoy95 you were correct on the voltage. The output 43v at the speaker side with a 60hz tone and 80 percent volume. Addtionaly everything was set flat to include the eq that everything goes through. I am not sure how to check the other voltage (using a multi meter hooked to what?) . I noticed yesterday that I was able to play it real hard for 30 minutes (the amp got hot) but did not shut off until I switched music folders on the the USB that has all my music on it. It seems that the problem realy occurs when the engine is running.

Details: Kenwood 440mu Head unit Alpine mrp m1000 amp (2 or 4 ohm) Monoblock JL 10w6v2 Sub (2 or 8 ohm) Trouble shooting: Ohms read at amp with sub hooked up (1.5-1.9 ohm) Ohms read at sub (2.0) Gain at amp adjusted 43 Volts Using largest gage whire possible for power and ground Volts at remote on 10v Problem: The sub keeps kicking off but the power light is still on at the amp. The amp is warm (not hot) and the system will play for a while and then stop. when I turn everything off and then back on it will work again for a while. I have an aux input into the deck that has my portable satelite pluged into it. It is extremly frustraiting. I do not want to go out and replace all three to find out it is only one component. Looking for any help or guidance. The equipment is in my boat and it is run on a seperate battery.
