If the amp light is one and the protector light wasent on then I bet you blew your speaker??? take an ohm meter, measure each speaker with nit disconnected from the amp.. If they all measure what there suppose to( like 4 to 8 ohms) then the amp blew out and unless you have training on solid state electronic repair, you should seek a pro to fix the amp for ya.. Good Luck

There are a lot of problems that can cause the amp to apply DC to the speaker terminals.
Before we go any farther, you should know that this amp stores enough energy to kill. When power is applied, the transistors must be clamped to the sink. After removing power, you MUST wait for ALL LEDs to go COMPLETELY out.
You need to CAREFULLY measure the DC voltage from leg 1 to leg 3 of all of the output transistors (the ones you changed). Post a list of the voltages and circuit board designation (FETxyz) for any that read more than 1v.
Do NOT let the probes short to other pins or to the heatsink when measuring the voltage.
Remember... High voltage and lots of stored energy. Be careful.

There are a number of things that can cause it to act as you described. Have you pulled the covers off of it yet to see if you can see any problems?
If you do, disconnect power from it and don't touch ANYTHING on the board when ANY of the 3 LEDs (2 are not visible from the outside) are lit.

I had same problem with a TC6001 and get solution from MTX, not send to MTX instead MTX kindly sent a quotation for parts to be replaced, I can tell you what parts need to be replaced if you still need a solution.

This is common with pioneer head units, the rca jacks are not properly grounded and this lets engine noise come through the rcs cables. This thread explains a fix http://www.caraudio.com/forum/showthread.php?t=337644.
