I have a Pioneer DEH-P690UB deck that I'd like to install in my 2000GT, it currently has the stock Mach 460 system & deck, do they make an adapter that would allow me to use the stock amps with the Pioneer? Thanks.
Just an FYI for anyone that might read this thread, the Metra 70-5519 harness does NOT work with a 2000 GT, even tho the description says "2000-2001 Ford" in reality its referring to a 2000 Lincoln and a 2001GT, For a 2000GT You need to use the Metra 70-5511 Harness or if you plan on adding a subwoofer and another amp but still want to use the factory amps for the front / rear speakers then the 70-5510 Harness is the one to get ..but keep in mind the 5510 would require your head unit to have 3 RCA outputs if you add a subwoofer, luckily my Pioneer had 3. (I ordered the 5510).
