see now that helps that not only is it aftermarket but that all the speakers are out. Most aftermarket decks will turn the amp off if one of the speakers grounds/shorts out. the easiest way to test this is to disconnect one of the speakers at a time. The rear speakers you can just do from the trunk but the fronts you will probably need to pull the deck out for the easiest way. Disconnect one speaker at a time and if the speaker wires for that speaker is shorted somewhere the other speakers will turn on. At that point just check all the connections by tracing the wire and you should find your problem pretty easily.
If after disonnecting all the speakers nothing happens, pull the deck out and take it to a local shop to have it bench tested.
