Over the years, the technology used to create audio amplifiers has grown by leaps and bounds. We consider it our mission to use our expertise in developing the latest technologies and to bring you the absolute best sounding amplifiers on the market at a reasonable price. From its clean, sleek design to its high quality components, you will be amazed at the quality and power that these new Proton amps offer.

The RXD-F20 is a 4 channel amplifier with 1600 Watts peak output and 300 Watts
CEA-2006 rated RMS power. You can also bridge the amplifier and get 2 x 200
Watts RMS @ 4Ohms. 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. 

One of the tricks to determine the real power of a car amplifier is to multiply the fuse rating by 10 to determine the true RMS power. This formula almost always works within 20 %. RXD-F20 features Dual 25 Amp Fuses. Compare this to other amps on the market with similar fuse ratings and you’ll see that with the RXD-F20 you are getting your money’s worth and then some.

This unit also features a high speed MOSFET power supply, studio-grade bipolar output stage transistors and ELNA brand audiophile capacitors. It has a fully adjustable 12dB Octave cross over with differential circuitry.

Other features include Auto-Start Smart turn-on (This function senses when there is a signal from the head unit and automatically turns on the amplifier hence no need to run a Remote Turn-On wire), a fully adjustable 12dB bass equalizer, 2 ch 4 ch input mode switch, mute and delay soft start technology, and a crossover band-pass control. The RXD-F20 is protected by a full IC controlled circuit and has professional peak limiter circuitry guaranteeing distortion free musical playback at all levels.

One last point I want to make about this amplifier is efficiency. The circuitry of this amplifier is a class A B circuitry. Class A B is known to have amazing sound quality. Pro audio amps usually all are class A B. Class A B however is not known for its efficiency. To make this amplifier more efficient we simulated a class “G” amplifier. Class G is technology that switches the rail voltage depending on how much power is being used. We have similar technology built into these class A B amplifiers which make these about 65-70% efficiency which is just amazing for a class A B amplifier.

We are so confident that you will be extremely satisfied with this amplifier that we are giving every customer a 90 day money back guarantee. So purchase the amplifier and try it for 90 days. If you are not happy, we will call tag it and cover return shipping costs and refund you all your money back. (Amp must be complete with accessories and original box please).
