    maybe..

    is the connection from the amp to the sub bridged?
    if it is all you have to do is un bridge it simply because ur amp cant handle the load

    or just buy a new amp =) prefferably a monoblock

    your amp cant handle the voltage that the head unit is giving it so it goes into protection mode and shuts off.

    short term solution - turn the gain down on the amp so it isnt being worked so hard.
    long term solution - if you want that much bass or more get a better amp

    yes totally agree...you have set the gain too high and this is clipping and leading the amp to go into protection mode as it is overheating
    so turn ur gains or if u have a bass booster down and that should solve it from cutting out

    Lots of the same solutions.
    Not really helpful money wise

    Fair chance it could be your amps earthing, its happened to me before.
    Make sure your amp has a solid earth & solid power supply

    An amp going into protection usually isnt caused straight away by going to a higher volume, generally from experience it will occur Intermittently and not all the time.

    It could be the load but then again i think it would still happen at lower volumes.

    yup the amp circuit protections trips off. Turning off and on the head unit resets the circuit protector.

    check the grounding
    i had an issue with the grounding in my old car
    when the bass would come on the protection light will come on at the same time
    if i turned it up louder the light would come on stronger and the amp would cut off
    put a metal washer between the bolt head and the connector and bolted it back down into the chassis and it was all good
