Summary: I have to be honest, I am a solid novice when it comes down to high quality audio - but I am learning very quick. Recently starting playing HD music files and deleted all my MP3's. I have two Orion HCCA 10" Dual 2 Ohm subwoofers that are now powered by this little amp. This is amp is about a third of the size of the original amp I had installed and this JL amp is just as, if not a little more, powerful than the previous amp (not a JL).
Pros: Runs cool, easy to tune, very small and easy to install almost anyway. Probably could have put this in my glove box
Cons: Honestly it's hard to think of a negative yet, I have owned this amp about 6 months and still haven't had an issue.
Summary: Great purchase but had a problem with the amp (red light). It happens and Crutchfield was great. I called with the issue was not on placed hold and the technical adviser was professional and thorough. Got a replacement in four days. It is pushing my JL Audio Stealthbox (10 inch). Plenty of power with no clipping (provided you have properly tuned the intensity as per JL Audio instructions).
Summary: Bought this amp to pair with a JL cp108lg-w3v3. I was considering the Alpine 500/1 but decided that the additional features and JL quality were enough to justify the extra cost. Mounting is a breeze and the power output is more than enough to power my sub. I am running through the stock stereo in my '13 Toyota tundra so the sound quality isn't exactly what you would get with preamps and a real EQ but the amp pushes the sub great.
Pros: More features, build quality, doesn't over heat.
