Check your speaker load. It probably should be 4 ohms per channel. Also, if you are bridging then you must double your ohms load. It may be that your old amp could tolerate a lower impedence (ohms load) than the new amp. Do this now so you don't fry your amp. Good luck.

If the amplifier goes into protect when there are no speaker wires connected to the amp, the amp is likely defective. The most likely culprit is shorted output transistors. If it's new, return it to the place of purchase for repair/replacement.

You will need to show it to a service technician as it seems the output section has blown so it remains in protect mode. One reason (could be) that the input to the amp was high and may have been clipping for some time before the amp decided it could take it no more

SOURCE: protection mode?
What guage of wire are you using to power the amp? Should be 6 guage or larger. Do you have a good ground to the frame of the car (metal inside trunk area)
Is the amp new or used?
Also your speakers could be shorted inside. Use an ohm meter to check them. They should be about 4 ohms useually. Test them UNHOOKED from the system.
Try different spakers. If you cant solve the problem, the amp might be damaged.

first thing check all ground and power wires and make sure ur rca wire make sure it isnt cut in anyway. after that unplug ur sub and unplug the negative wire from ur amp, while its out check the fuses on the amp if all is well put all fuses back if not get new. then plug the negative wire back in if protect goes off check for heat and if no heat inspect the wires from speaker out put all the way to the sub, look for any wire touching another this is were most problems are even the smallest wire can trip a protect. if u still cant find the problem. an amplifier specialist is in order.if its trashed go on ebay and buy a powerbass there goin cheap right now. hope i could help
