This amp has my highs screaming! Great amp!

By james on December 24, 2004

Clean sound!

This amp turned my Type-S series Alpine components into Boston Acoustics in my opinion! I know another review says it's not enough power, but the efficiency of your speakers has alot to do with it. This amp has power, and plenty to spare. I'm only running it at 4ohm per channel and it's so clean. Runs cool, no problems there. And I'm sure if I wanted to, it will have the grunt to toss around some subs due to the Low Pass on it. I would recommend this as a highs amp, sub amp, or both! Bridgeable and flexible. What more could you ask for the price?!

FYI Revised

This amp IS NOT as powerful as many think. To get it to run my highs loud enough for me. I had to Parallel my left [front and rear coaxials together] (and the same on my right side.). To the 2 bridge channels (from bridging all 4 channels) from this amp. Now it’s loud. But running one channel per coaxial (4 channels on 4 coaxials) was very weak to me. In comparison to my old P.G. ZX 350 @ 2 ohms. Caution only do this with a radio that has hi-pass RCA outs. Then Activate the crossover on the amp. And use A Bass Blocker per coaxial connected in this setup. 100-500 micro farad, or speakers could fry. Even now with my system up about 94-100% I can smell near burning voice coils. But I just might have my amp gains up a bit too high. The two 2 ohm mono's won't hurt the amp. As long as u set it up exactly the way I've explained. It will only heat the amp up a bit. Sound Quality (of this amp for pushing highs) is not all that.
