Question about Power Acoustik Car Audio & Video
I tried changing the fuses and it does not work it still shine the red light
Check that no speaker wires or some other wire come off, If they all look okay, There is a internal problem with the amp, It will have to be taken in for repair,

1) Make sure the amp is properly connected to +12V power source. 2) Make sure the amp is grounded well, directly to metal - if you have a voltmeter, an easy way to check the first two is to see if there are 12 volts across the power and ground wires. 3) Make sure the speaker output wires aren't touching each other. If none of these are the case, there is an internal problem with the amp and it should be serviced or replaced.

SOURCE: protection light
take the amp out and hookit up to the car battery and let it charge then unplug it do this a couple of times then rehook it to the cars audio system it sounds like your amp may be locked..
also check your speaker wires from amp to speaker box then from the back of the box to the speaker inside the box you may have a short..
thats where i would start.. hope this helps

short answer yes... Long answer... Amp Failure: There are many different ways that an amp can fail but the two most common failures are shorted output transistors and blown power supply transistors (< those are not blown). There are several types of protection circuits in amplifiers. The most common are over-current and thermal. The over-current protection is supposed to protect the output transistors. Sometimes it doesn't work well enough to prevent the failure of the output transistors but it will work well enough to shut the supply down before the power supply FETs are destroyed. If the amp remains in protect mode, goes into protect mode or blows the fuse as soon as the remote voltage is applied, shorted output transistors are almost certainly the cause. If the fuse protecting the amp is too large, if the protection circuit doesn't respond quickly enough or if the power supply is poorly designed, the power supply transistors may fail. If you see a lot of black soot on the power supply transistors (near the power transformer), the power supply transistors have failed. Soot on the board doesn't necessarily mean the transistors have failed. Sometimes, technicians don't clean up the mess from a previous failure. Transistor Failure/Checking Transistors: In general, when a transistor fails, it will either short (common for output AND power supply transistors) or open (common for power supply transistors). Transistors act like valves. They control the current flowing through a circuit. A shorted transistor acts like a valve that's stuck open (passing too much current). In the case of an output transistor, the shorted transistors tries to deliver the full rail voltage to the speaker output terminal. If you've ever seen a damaged amp that pushed or pulled the speaker cone to its limits when the amp powered up (common on some Rockford amplifiers), that was almost certainly due to a shorted output transistor. When checking transistors, you most commonly look for shorted connections inside the transistor. You do this by using a multimeter to look for low resistance connections between the transistor's terminals. Note: I used the terms short and open on the previous paragraph. A short (short circuit) is a path through which current flows that should not be there. An open (open circuit) is a break in the circuit. It is most likely the power supply that has taken a ****.

If you are certain speaker isnt blown and you have correct phase wiring and so forth you have whats called a solder jump which is internal repair by dealer only! buy a new amp at dealer wholesale price here cheaper than having it repaired unless under warranty go here for wholesale pricing on almost everything audio wise:
