Description:

Many of today's power sports have very limited space to work in and tend to be a harsh environment for electronics because of the exposure to outdoor environments. Kenwood's compact performance amplifiers are small in size so they fit even the most limited installation areas. The amplifiers also use a conformal coated main pcb (printed circuit boards) which offer extra layers of protection to help prevent moisture or damp air from damaging the product. - Rms power output 2o: 75w x 4 - perfect for boats, atv's, motorcycles, cars and more - dimensions(wxhxd): 6-1/2" x 1-3/4" x 3-7/8".

Description:

The RXA-F1 is a 4 channel high power amplifier with 1,600 Watts peak output, 800 Watts RMS output (4 x 200 @ 2 Ohms). You can also bridge the amplifier and get 2 x 400 Watts RMS @ 4 Ohms. The CEA-2006 compliant rating is 65 x 4 @ 4 Ohms and 95 x 4 @ 2 ohms <1 THD. Most brands do not use CEA compliant ratings because quite simply they do not want you to be able to compare their amps to others on the market. Over here at Rockville, we want you to be able to compare our amps to any brand on the market. For this reason we are supplying you with multiple ratings. The CEA compliant rating should be used when matching up or comparing this amplifier to other CEA compliant brands such as Kicker, Rockford Fosgate, Alpine, etc. We also supply an RMS rating which should be used when comparing with great brands that are not CEA compliant such as Hifonics, Earthquake, Powerbass, etc. The peak rating is simply what the amplifier can hit for a split second at the highest point of a song. This rating from any brand is not really important. RMS and CEA ratings truly are the most important.

Buy the best 4 channel amp from Amazon.com

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.
