i have a 2000gt with the mach 460 system. i wanted to put an amp in in but i didnt know if it had the preamp outputs on the stock stereo. it is a tape deck with the cd underneath.
What are you lookin to add a amp for? sub or amp for high's?
You can take an put in a "RCA Output converter" which will take you speaker wires an convert to RCA's for your amp?
really works with a sub setup?
High end stuff like door speakers and vocal speakers should be run with good RCA's All the way from headunit to the amp? for better clean sound?
Well, they do run a preamp signal from the head unit to the various amps so if you have the right RCA adapter harness you can do whatever you want. If you're just adding a sub then a line level converter off the back speakers is probably the simplest option and will sound just fine.
