I recently upgraded from a 900 watt Interfire amp(sry, don't know the rms...)to a new KX1200.1. one my my friends uses two amps in his truck. One for his highs, and another for his lows... Could I put this amp to good use and set it up like that, or am I just better off selling it? Any help would be appreciated
entirely depends on the amp if the interfire is a class D sub amp, then no, it only works on subs if its a class AB two channel amp that has a power output that'd work for your full range speakers, go for it.
