Ive heard the mach 460 is a pain to mess around with why is this so...I was thinking of putting a new cd player in my car so I can play mp3's but I dont know it sounds like it would be a project
If you are trying to add subwoofers to yur mach system you cannot tap into your back speakers w/ a line out converter. What you have to do is do an amp bypass and put an aftermarket radio in the stock radio's place and use the RCA's off of that. It's just the way the mach system is designed, It's a pain in the ass and I have to deal with it everyday at work. lol
there is a tech article on this site on how to install an aftermarket deck into a mach460 equiped car. its a PITB and your almost better off ripping all the speaker wires out of the car and starting over if your gonna do speakers, deck and subs. the reason for this is the weird ohms that the 460 runs at.
