Did you buy the right U.S. Amp? There is a U.S. Amp for every purpose. If your needs require maximum amplifier power into 4 or 2 ohms per channel, or 4 ohms bridged, use one of the Xterminator “X” models for the best results.
Adjust the source unit volume as high as possible without distortion. Increase the amplifier gain until the amplifier distorts, then turn the gain down slightly until the signal becomes clear. It is desirable to operate the amp at the lowest possible gain setting to help reject spurious system noise.

Unless you are one of those people who uses your amplifier to play a sine wave, (in which case you are on your own) your amp will not draw peak current all the time when playing music. This isn’t rocket science , but it gets the job done.

By default, we have become battery experts, so much so that we have our own brand, aptly named the U.S. Amps SPL Series, sold through our Motorsports and Consumer Electronics divisions. The SPL Series consists of two 12 volt models, the SPL- 1000 and SPL-2000.
SPL Series Batteries are available at your Authorized U.S. Amps Dealer, or they can be ordered factory-direct using the form at the back of this manual, or from our internet web site, www.usamps.com. Additional battery information is also posted, with an email address for technical questions.
Smart Amp Technology: Smart Amp Technology: Both models incorporate a non-computerized version of SAT (U.S. Amps’ exclusive Smart Amp Technology) that precisely monitors each amplifier channel, the battery voltage, and amplifier temperature. In the event of a fault condition, SAT will activate to protect the amplifier from damage.
