I need a new multi-channel, preferably a 175.4, while mine is in for repair. I have 2 lvl2 8s and a 1.2k mono amp that are basically brand new. They were in my car for a week while waiting for 12 to get hooked up. I will trade the amp and 1 sub straight up for the 4-channel. If you want the second 8", I will let it go cheap.
