Im thinking about buying the 560.2 its rated to run 140 x 2 @ 4 ohms Im either going with this amp or the JL 300/2 to run my componets Diamond s600a(I like brighter highs). I sold my diamond audio d3 400.4 that I was running my cdt componets off of. It was to much power bridged and not enough not bridged. Just the wrong amp for what I needed and turning the gain down wasnt an option because my pre outs are 5 volts. And diamond recs to have gain down already with 5V pre outs. So I was looking into this amp.It will put out thepower Im looking for. I would hate to spend another $130 on the JL if this Soundstream amp will get the job done nicley
