    Power house!

    Got this to replace a crescendo audio S4 amp that makes 880w rms at 13.8v. This one is noticeably more powerful and does run a little louder but seems to stay cool. The sound is crisp, loud and clear. Very clean power with plenty of overhead. I'm running 140w RMS speakers and they do seem to appreciate the extra overhead that comes with the amp. I've always ran conservative amps on very powerful speakers but as of late, I've found myself doing the opposite. I'm also waiting on a SFB-5000D to replace my SFB-3000D. I'm addicted to power. Lol.
