I couldn't believe the sound quality and power I was getting for such a great price. I have it hooked up to one 12" power acoustik mofo with dual 2 ohm voice coils in a ported box. That setup is in the hatch of my ford focus. The bass is crazy! Not only that but this amp controls the sub very well and blew me away with the quality. I just had a diamond audio D6 amp 1500.1 go bad on me a couple of weeks ago and the Orion was my choice to replace it. As far as a bass amp, the Orion is the better choice. Sorry Diamond audio, your amps don't compare. One last thing, the sales department for Online Car Stereo was very awesome to work with. They took great care of me!
