Phoenix Gold RX2 400.4
Configure as a 4ch for an active components setup or as a front/rear stage amplifier. How about for a full system? Setup as 3ch mode you can run your front stage and a subwoofer. Configure in 2ch mode for 200 watts x2 on whatever you choose. Anyway you configure it, you will be rewarded with efficient sound and musical quality while wrapped in a sleek, low profile chassis designed for versatility.
RX2 series amplifiers are the reference for style and value in any installation. Built with the legendary Phoenix Gold reliability, they feature heavy duty heatsinks, robust unregulated power supplies, and oversized direct input power and speaker terminals. They also sound sweet thanks to the audiophile-grade output transistors. We made upgrading your stock system easy by allowing high level inputs, so you can keep that hard to replace radio, and still upgrade the sound. RX2-series amplifiers are ready to impress with their effortless ability to provide power and clarity while keeping the chassis at a convenient size for any installation. The devil is in the details, so it just made sense that we allow the PG name plate to be removed and turned to match the orientation you might need for your install because we know you're going to want show off your system and make all your friends jealous.

Power Specifications - Full Range Channels
The RMS power rating is the measure of continuous power that an amplifier can output, or a speaker can handle. It is the most accurate depiction of real, continuous power that the industry has so far.
If the final impedance of your speakers or subwoofers equals 4 ohms, this is how much power this amplifier will supply at that ohm level. The higher the RMS wattage, the more clean and loud your music will sound.

Amplifier Specifications
An amplifier increases the power of the signal being fed to it by taking energy from its power supply and matching the signal but increasing its amplitude. Amplifiers use many different methods for converting these electrical signals and have been categorized into classes.
Class A/B: Greater than 50% of the input signal is amplified while the other percentage is “off”. These amplifiers have a small amount of current flowing through the output transistors all the time which almost eliminates crossover distortion. Class A/B has great sound quality but is not as efficient as class D. These amps are most commonly used to drive speakers.
Class D: Also known as switching amplifiers, class D amps have output transistors that are completely turned “on” or “off”. This means that when the transistors are on, there is almost no voltage across them but when they are off there is significant voltage but no current flowing through it which makes these amplifiers very efficient at the cost of sound quality. These amps are most commonly used to drive subwoofers.
Other Classes: You may see classes such as GH, bD, X, FD, etc. by some manufactures. These amplifiers tend to be either class A/B, D or a hybrid of the two but with improvements to their designs that can make them more efficient or offer better sound quality.It is measured during a brief musical burst, such as a sudden drum accent. Some manufacturers display peak power ratings on the face of their products to increase the appeal.
The RMS power rating is more accurate, and we recommend using it for product comparison.
RMS power is the amount of continuous power, measured in watts, that an amplifier produces is called RMS power. The higher the RMS figure, the louder and cleaner your music sounds.
The RMS output figure is much more accurate than the peak rating when comparing products.
A crossover is a type of filtering system that permits only certain frequencies to play. A Low-Pass (LP) crossover allows only frequencies below its setting to get through which is good in the case of some subwoofers. A High-Pass(HP) filter allows frequencies above its setting to pass through, this is normally used on speakers.
When a crossover is set to FULL it means no filtering is added and the full frequency spectrum is allowed through the amplifier. Filtering is important because feeding a speaker frequencies it cannot reproduce effectively creates distortion.
High-Pass (HP)

Subsonic
The steepness of the roll-off slope is measured in dB/octave and refers to the rate of attenuation (lowering of volume) outside their pass bands.

This rating applies to both external car amplifiers, as well as the amplifiers inside of in-dash stereos.

I hooked the Hifonics BRX1200.1D up to my old 12's and it's pounding the guts out of them. I give Sonicelectronix.com and the products I've ordered 5 star's across the board. I will continue to buy my electronics from Sonicelectronix.com. Thank you Sonicelectronix.com____
