    2 channel amp , 2 subwoofers 4 ohms help! ! ! ! !

    Well im having trouble with this setup , i had it connected , bridged. the positive to the positive , negative to the negative. They came in a factory box already connected. But im having trouble , everything was fine , was bumpin for awhile like an hour , then it just shut off. Now every 10mins or so , it just shuts off on me. What would be the problem? has it happened to anyone?

    gonna need WAY more information than that, what amp, what subs, what ohm rating are they, how are they wired inside the box, how is the amp wired to the box...
    sounds like the amp is going into protect though

    Probably not 2 ohm stable bridged.

    you need to find out what ohm they're wired at from the factory

    Re: 2 channel amp , 2 subwoofers 4 ohms help! ! ! ! !

    If it's a prefab I'm guessing SVC 4ohm on each which would render a 2 ohm load. I know a lot of amps aren't stable bridged at 2 ohms and that's my guess as to what's happening.

    He means you overloaded your channels and probably blew something inside the amp. Disconnect everything and inspect the internals or if you're worried about that, see what you can smell. If it smells crispy, you're done.

    Amp is not 2 ohm stable bridged. Try connecting your subs to one channel of the 2-channel amp and see if you can recreate the issue.

    turning on and off every ten minutes sounds more like going into protect from having a too low impedance on the amp, however you will eventually blow ur amp if u havent already

    If you're savvy enough to check the wiring on your subs, make sure you're in series between each sub. You'll put an 8 ohm load on the amp which it CAN handle bridged.

    Visual inspection of the internals. Voids warranty somtimes, though.
