US Acoustics (at least the previous USX line, what I've previously used numerous times) was rated @12.5v for RMS power. So, usually they were slightly underrated. They are solid amplifiers, and if bought authorized offer a THREE YEAR warranty. I love them, and have never had problems with them at all (can't say the same about Profile //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif ). My g/f is still using a USX4065 I bought near 3 years ago.I would class US acoustics right alongside Profile. Slightly over-rated (you'll likely not get quite rated output) but uber-reliable and tough to beat for the money. I've owned a few US acoustics amps and I have to wonder if they aren't made in the same buildhouse as Profile as they resemble one another more than a little inasfar as how they're put together.
Anyone looking to get into car audio on a budget (for amps anyway) I usually tell them to look to Profile or US acoustics first.
