[QUOTE="n2audio, post: 3722100, member: 540940"] 120's not a small alt. I had a 110A in my old Tbird with an old battery that ran 1060w with no problems at all - very slight dimming at full tilt. 700w class D and 360 class a/b. Same system is now in my Contour with 130A alt and it doesn't even flinch. Most any class D will get you ~70%. The JL slash amps are unusually low, and some of the cheaper brands are probable sub 70, but some of the newer higher end brands are claiming mid 80's-90%. If you're looking at around 1000w, a 10% efficiency difference won't be drastic. I don't think it's enough of a reason to determine which amp to get, however, I do think class D would be the way to go. FWIW - if money's an issue here's an affordable option that's pretty similar to that Alpine but quite a bit cheaper.
