Video of dB25:

Description:

The dB25 is a 2 channel amplifier with 2,800 watts peak output and 700 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. The peak rating can be used to compare with brands who use peak ratings such as Boss and Power Acoustik while the CEA rated RMS rating can be used to compare with brands who rate their items using the CEA standard such as Kicker, Rockford, Alpine, etc. 

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 dB25 is protected by a full IC controlled circuit and has professional peak limiter circuitry guaranteeing distortion free music playback at all levels.

The RCA input accepts both balanced and un-balanced inputs. If there is potential inference in the car, the balanced input signal is less susceptible to noise.

The dB amps by Rockville use the top parts and components recommended by Rockville’s 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 world’s 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.

Each and every amplifier we manufacture is tested twice. Once at the semi-finished PCB stage of production, and then another test is done at the final assembly. We also run age tests on them. After this is all done, we hire a 3rd party independent company unaffiliated with our factory or with us to go to the factory and inspect 20% of all the production items. We test the power, the controls, and over 20 other tests. We guarantee these amps will satisfy you. We are so confident in your satisfaction of this amplifier that we will offer you a 90 day money back guarantee. If this amp does not perform as well as you expected we will send you a pre-paid shipping label and give you all of your money back. This means if for any reason you want to return the amplifier back for a full refund within 90 days, you can! (Amp must be complete along with the box).

About Rockville Quality Control Procedures:
The Rockville brand stands for Quality, Innovation and Value. We aim to deliver products twice as good as our competitors at a fraction of the cost of famous brands. All Rockville products go through the most rigorous quality control standards in the industry. Products go through months of extensive testing before they reach your hands. All functions and components are tested for quality. Rockville makes products that are virtually un-breakable! Rockville is one of the only brands in its class to have engineers and technicians test every concept model for weeks or months before starting production. Once production begins, Rockville sends product engineers to the factory to quality control every product. After production is complete Rockville has the head of QC in our overseas office test a certain percentage of all products from the production line a second time to ensure that the quality meets our strict standards. All Rockville products are backed with a hassle free warranty.
