I have a 1996 mercury sable and I just purchased a MTX Thunder 4202 amplifier from my friend and a subwoofer. I am a complete novice in the area of installations, but I am willing to learn. How should I go about doing this? There looks to be a connection right under the steering wheel that I would connect a harness to but I am not sure. I already have a 10-disc changer with a fm modulator hooked up to the radio that I paid someone to do. I would now like to connect the amp and subwoofer. Any help would be appreciated.
Look at this amp kit from streetwires to connect everything: https://www.crutchfield.com/S-DUoNxWkFsiU/cgi-bin/ProdView.asp?s=0&c=11&g=711&I=211PS8RI&o=m&a=0&cc=01&avf=N You will need an LOC also which takes a speaker level signal(it ties into a set of your speaker leads to get its signal) and turns it into a preamp output for your amp. Dont connect power to the harness under your dash. You need to go directly to your battery post with the + power cable and the ground cable needs to be grounded no more then 3 feet away from the amp on clean metal. If you need more details ask.

Thanks customsuburd, he gave me most of those wires, I think I need the LOC(is it the same as the speaker level to line level converter ?) How do I tie that into my speaker leads? Is that where the harness under the dash comes into play? I really want to understand this stuff.
