Just bought a 94gt convertible, thought it was worth $3500 for a gt with 91k miles. Anyway looked at the mach 460 deck and what did I see A CASSETTE, I guess the 8 track was in the 93's, lol. Anyway I have a alpine deck that I haven't used for a while, will the mach 460 system play nice with the alpine deck? I ordered a wiring kit off ebay, hopefully that will make it pretty easy. Also I have some pioneer 5x7's if the stock speakers don't wake up with the alpine can I swap those speakers in the front and rear? Thanks all and big thank you to all military and their families, past and present.
