I have 2 inexpensive mono block amps that are only rated for 4 ohms .. go figure.. I am going to wire these where the rca splits between these 2 amps and then put one amp on one sub and one amp on the other sub.. One amp is a cheap VR3 Walmart amp only rated at a 4 ohm load. 150 watts rms.. The other amp is a viosonik amp I was told it was 2 ohm stable but I don't think it is .. It is also 150 watts rms.. So one amp per each sub off of my sub out on my infinity kappa 3 way crossover.. Then I have 2 Rockford amps and one coustic amp these will run my front 6 1/2 , my rear 5x7's and my 2 sets of tweeters .... What do you think about the sub solution... ?
