okay so i've got a low level input on my 2000 watt pyramid amp. my car is a 2010 mustang with a shaker 500 system in it. how can i either remove the cover on the stereo to install subwoofer wires OR how precisely do i run the amp/sub off of the rear speaker?

 

Splice into the rear speaker wires, feed those into a Line Out Converter (LOC), and then the output of the converter should be RCA cables, which plug into your low level input on the amp.

 

if it has high level inputs then you can try them. Worst case scenario you will get noise and need to get an loc and move the location you tap the signal.

I have not had my head inside a '10 model to see the amp rack and know how to take it apart unfortunatly. All you need to do is find the speaker wires going to the subwoofer box and tap them, and then run the wire to the amp for your signal.
