I've been wanting to try this "little" amp out for a while and I finally found one for a good price locally. I know AB makes some quality gear judging by their presence in some seriously loud vehicles and I was hoping that the little brother was of similar build quality and performance. And, in a word... it is. I have heard rumors that AB shares a build house with Cactus and maybe DC, but I can't confirm this. Maybe someone else can chime in on that.
It's a sexy little 1k. It's clean and looks good. And other than the cheesy "hardcore spl amplifier
" moniker, there isn't anything Mickey Mouse about this thing. It has the classic hex key terminals and easily accessable and adjustable gain and crossover settings. Everything you'd expect in a higher end line of amp. It has 120A of onboard fusing as well as a protect circuit. I know you can't judge an amp's performance solely on fusing, but with 120A, I'm assuming the 1,000w rating is pretty accurate, but not so secretly hoping that it's under rated.
I wired my SA12 to 4 ohms just to insure that the amp was functional when I bought it. Listening to it on the ride home had me second guessing whether I actually had it at 4 ohms or 1.
You will hardly ever see a 4 ohm "clamped" number, but I had to see what it was doing since it sounded so good. With the gains set properly for 4 ohm operation, I got...
65 AC volts and 7.8 AC amps for 507w
at 4 ohm nominal rising to 8.3 ohms
! Lol. So yeah, I'd say it's doing rated. Well, at 8 ohms anyway. Lol.
I'll have more numbers on it later and post those in the clamped numbers thread when I start to put it through it's paces, but my first impression was that this was a good buy
and if you are considering a solid 1k amp, you might want to put the ol' 100.1 on your radar. There may be better power options for the $350 retail price tag, but if you can find a decent price on one used, don't hesitate.
