Hi, First of all I know that these products are different in terms of usage and design. I have JL Audio A4300 amp and driving a pair of Morel Tempo 6 and one JL Audio 10w3v3 sub. I have a little complain about the A4300(4*70 or 2*220 @4ohms) that I think it cant drive the Tempo 6s to get their full potential and also little bit lack of base control in compare to sub channel of Audison Srx3(Audison sub channel is 250w, but this is a dedicated channel so damping is very good). Now a friend of mine is asking to give his amp to me and get mine with a small mouth of money... The GZ amp is produces 4*85w + 250w @4ohms..... I can bridge the stereo channels too... In addition to this I think with a suitable HU, I can go for active setup in future. What do you think ?
