Amplifier shuts off

    Ok so I've been dealing with this issue for awhile. People keep throwing ideas at me and I put them into effect and they do hep somewhat, but not significantly.

    The issue is that my subs work and sounds awesome at low volume. after I turn the amplifier up significantly it sounds like it is working but when a hard hit from the music tries to make a sound, it shuts the amplifier off, or if say a bass guitar strums for more than probably 5-10 seconds it shuts the amp off. I have my subs wired in series and then parallel and measured them at about 2.0-2.2 outside the at the point where they reach the amp. my amp is 2ohm stable, i have a backup battery and a capacitor. I was told a capacitor would fix this, which it does for the first couple of minutes of play and then it doesn't really do anything it seems.

    Oh and my Bass on my radio is set to flat for the subwoofer. my remote switch is set about 3/4, and my gain is set to about 1/3 on the amp. Bass boost on the amp is set to about 3/4. I checked every spot fuse for weakness or blowing, checked every power supply including the power coming into the amp and the remote turn on wire for full voltage and everything is about 14.4-14.7 I was told is normal when the car is running.

    Subs: 2x Kicker CVR12 dual 2ohm coils (Wired series to parallel for 2ohms)

    amplifier: Kicker DX 1000.1

    How many volts are your pre-amp out-puts

    Check your connections, make sure no exposed wire is contacting metal. Because my mids and highs were doing this, then I went in to look at my solders, sure enough they were touching the metal speaker cutouts in my door. This caused the music to stop and the subs to continue playing. Sounds to me like your problem is the same as mine but with your amp.

    turn off your bass boost.

    how thick is your power and ground going to the amp?

    Ok Just tested a couple other spots. My remote wire is getting roughly .5-1volt less than the incoming power. the cables going to my subs from the amp are at 34.8~v, is that normal? checked my wires from radio to amp and amp grounds and all in between, nothing is showing any wire except where needed and in them spots it is not touching bare metal. I believe I have 4 guage because that is the largest the amp would use. The capacitor seemed to help for the most part, is it possible i need another battery?

    Well I dont technically have a way to check that because I don't have a way to bust into the circuit to test amps, I just know it is supposed to push 1000W because thats the size amplifier it is
