Ok guys I have seen the posts on here about how to install an aftermarket headunit with the Mach still entacted, but I am wondering if anyone has detailed instructions on how to remove the Mach system entirely and how to properly rewire it using an aftermarket amplifer and new speakers. Any help is greatly appreciated since the stereo shop I go to and trust told me that I could be looking at $200 to remove it, rewire the car, and install the new amplifer . Oh and I have a 2002 Mustang. I know 99-04 are the same but they use the Mach name for all Mustangs so I figure I'd better specify.
