It should be right at the front of the engine. You don't say if you have a 4 cylinder turbo, or a V6. For the 4-cylinder turbo, there is a black cover on the top of the engine held in by 3 big screws. Twist those 90 degrees and remove the top cover. Then there is the top section of the timing belt cover that is held on by 2 clips. Undo those clips and remove the cover. You will see near the top of the engine 2 bolts that hold the sensor on the engine. It is not a large part, and a Google images search should show you what they look like. Unbolt it, and follow the connector cable and disconnect it. There is nothing special to putting in the replacement other than to torque the bolts correctly. If you don't have a torque wrench or can't find the torque specs, then just make them snug. The head that the bolts attach to is aluminum and it probably needs less than 10 ft-lbs torque. If you strip those bolts, you have a huge problem on your hands, so do the tightening gently.

Because your amp is overheating. The transistors are attatched to the heatsink inside the amp. Alongside these transistors is a sensor that shuts down the amp when it reaches a certain temperature. A very easy repair. Clean up the old paste and add new thermal paste.

I have seen circuit traces litterally burn up from reverse polarity. Also the capacitors on the 12 volt main line can smoke and causing the DC/DC circuit not to function. Traces can be repaired with the proper sized copper tape and capacitors are cheap. The only way to be sure is to open the unit up, look for strange liquids and evidence of burn or fire.

i would get me a 400 watt pioneer amp that ran the same ohms as my speakers maybe a 500 watt to much power on 6.5 will pop them dont ever goby max power its to much for them

It is a plug located to the left of the RCA inputs on the opposite end of the amp where the power and speaker outputs are. You will need a plug with pigtails (most likely available from JL AudioCheckout this link for a picture.:http://www.sonicelectronix.com/pictures_new.php?id=2789&picture_id=111453
