FS: Xtant 603x chrome amp

the last time i checked my 603 was a 3 channel amp.

If you look on the amp the rear channel outputs are already built in, so you don't have to dick with it.

i gotta check that out. i had my friend install it. hope someone buys it, its a great sounding amp.

The rear channels on that amp are called passive outputs. You have no fader so you have to use attinuation moduals to get the sound you want. It is a good amp and I have one I used in my M3 and and liked it once I got the tunning set the way I liked it.
Its not a hard amp to work with but its also not a novice amp that is easy to tune. You have to buy the moduals to tune it for the passive outs and the crossovers.
