I thought I at least had my mind made up to get the JBL 1200.1 for whatever sub I get, but I ran across what sounds like a good deal on a 5-channel amp, the Hifonics Zeus Z 8000. I know it is strange to compare a 5 channel amp to a mono amp, but if the Hifonics delivers it's rated power, it would save me from possibly having to upgrade later. I was just going to use my head unit for my 4 speakers with the JBL. I am interested in SQ, not spl, and I think 200 or 300 watts to a sub would play as loud as I could stand to stay in an ext. cab pickup with it. What do y'all know about hifonics?
