  • FULL RANGE: With a Full Range amplifier you not only have the option to run your speakers, but also your subwoofers
  • VARIABLE GAIN CONTROL: The gain control is not for adjusting volume. It simply adjusts the amount of signal that is coming from your receiver and going to your amplifier
  • LOW / HIGH LEVEL INPUTS: A low level (RCA) input is measured in voltages. A high level (/- wire) input is measured in wattages. Both essentially carry signal from your receiver to your amplifier to your speakers

Description:

The dB45 is a class AB 4 channel high power amplifier with 3,200 watts peak output, 1,600 watts RMS output, and 800 watts CEA-2006 rated power. Here at Rockville we offer the best value in car audio. We therefore want to make it easy for you to compare our products to any brands on the market. So we provided 3 ratings for all of our car amplifiers. We provided a CEA compliant rating, which you should use to compare this amplifier to other premium brands that make CEA compliant products such as Kicker, Rockford Fosgate, Kenwood, Pioneer, etc. We also supplied an RMS rating that is not CEA compliant, but has become standard in the industry. You should use this rating when comparing with ratings from brands such as Hifonics, Earthquake, DB Drive, etc. Lastly, we also supply a peak rating which almost all brands in the industry provide. This peak power is the amount of power the amp puts out at the loudest moments during a particular song.

This amp has a fully adjustable 12dB/Octave crossover with differential circuitry. Other features include a subsonic filter, a fully adjustable bass equalizer, and mute and delay soft start technology. The dB45 is protected by a full IC controlled circuit and has professional peak limiter circuitry guaranteeing distortion free music playback at all levels.

The dB amps by Rockville use the top parts and components recommended by Rockvilles very own engineer. These amps are the best sounding out of any series we have ever created. They perform more efficiently resulting in even dB of sound. We created them to be 2 ohm stable just like the worlds most famous amps by Rockford Fosgate, Kicker, etc. If you compare our amp to the most famous amps you will find our amp can compete and, in my opinion, surpass the performance of anything in its class.
