wiring amp to factory head unit?
You can run the amp wire through the fire wall after removing the car computer there will be a gromount and just past the wire through there.
To get a signal you use a hi/lo level converter which turns speaker level signal into low level. Some amplifiers also have speaker level inputs on them that sense when a signal is coming into the amp and use that as your remote turn on instead of having to run a seperate remote wire. This is actually how the stock Monsoon turns on.
