1999 mach 460 install
ive heard these cars are really hard to install because of the stock amps needing to be bypassed or osmething. i got a new headunit and just purchased some infinity subs but do not have an amp yet. i will install very soon after i buy an amp but how will i be able to do this. i have the wiring diagrams but dont know exactly what to do. thanks for the help
its really easy, go to crutchfield and find the wiring harness for your car. It will be two seperate harnesses. There will be a black box on one of them the has screws to adjust, just cut that black box out and it will work fine. That box takes the speaker output from the stearo and brings it down to a rca level. The amps in the mach 460 will work with rca level inputs but sound much better with speaker level signials. I just did this about 2 weeks ago and it sounds great, so much better than the stock system
