mach 460 sound system have preamp output?

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?
:nice:
 
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.
