my buddy has it in his boat and loves it . 3 amps im not sure of specifics but hes got subs and tower setup . he did have to return tyhe first one he got but the new one works great
RF has same exact unit, same exact specs, different name on the head....30% cheaper or so, depending on where you get it. No brainer IMO. I've got the rockford and love it, btw...excellent unit.
