I went to Circuit City to look for a new receiver. When I told them what year my car was(2000 GT), he told me they wouldn't touch it. Something to do with the Mach 460 system. He said they would have to totally run all new wire to all the speakers and I was looking at a 1500.00 job. I went and asked another friend of mine about this and he said that a new receiver is an easy install with my year. That it was the 01+ with the in-dash 6-disk cd changer that need to have the speakers rewired. Can anyone help me with this? Also, will I have to bypass the Mach 460 amp and just use the one in the receiver since I am using the stock speakers? My friend also said there is an adapter plate that I can get that hooks to the back of the new receiver. Is this correct also?? Thanks in advance.
