    I have an Alpine iva-c800 flip out monitor, an alpine navigation unit, an alpine amp, and an infinity kappa perfect subwoofer. During certain points in certain songs, the entire system just shuts off. It's usually during really heavy bassed songs. Anybody know what's going on? The only thing i can think of is that my head unit isn't rca cable connected to my amp, it's got wire > rca converter. That's the only thing i can think of, but i dont want to have to rewire it all just to test it. Also think a capacitor might help???

    Thanks for your help in advance,
    Brds

    capacitor will not help. Probably would make it worse!

    RCAs are not the problem.

    How did you run power for the amp?

    so the headunit goes out? Does it come back on immidiately?

    whats your voltage at when this happens?

    are you running the main speakers off of the head unit? Are they at 2ohm or 4ohm?

    Not sure about the voltage. Running of main speakers... 2 ohm for main speakers and 4 for sub i believe.

    that could be your prob. 99% of head units don't like below 4ohm... head unit is likely going into "protect" mode.

    Disconnect the mains for a test, then play some bass-filled songs that usually shut the system down, and see if it still fails. If it works, then you have nailed your problem.

    If that is the problem, you need to either run a 2-ohm stable external amp, or re-wire so the load is greater than 4ohm.

    I ran 8ohm on my volvo...
