Description:

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 and of course 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 Phenom amps offer.

The RXD-M2 is a mono amplifier with 3,000 watts peak output and 750 watts Dyno Certified 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 Dyno Certified RMS rating can be used to compare with top brands 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-M2 features Dual Maxi fuses with a rating of 40 Amps each. Compare this to other amps on the market with similar fuse ratings and you’ll see that with the RXD-M2 you are getting your money’s worth and then some.

This unit also features a high speed MOSFET power supply and studio-grade bipolar output stage transistors. It has a fully adjustable 12dB/Octave cross over with differential circuitry. Other features include a subsonic filter, a fully adjustable bass equalizer, mute and delay soft start technology, a phase control switch, and a dashboard subwoofer control for added convenience. The RXD-M2 is protected by a full IC controlled circuit and has professional peak limiter circuitry guaranteeing distortion free musical playback at all levels.

The RXD mono amplifiers took years of engineering. A lot of new technology went into these amps. We call this technology optical coupler Class-D. This new technology gives the amplifier punchier bass compared with a typical class “D” amp. A major difference in our OC technology is the preamp input stage and output stage are separated in circuitry. It is less susceptible to noise, which typically is picked up from the preamp input. The RCA input accepts both balanced and un-balance inputs. If there is potential inference in the car, the balanced input signal is less susceptible to noise.

The Phenom amps by Rockville use only the top parts. We use Siemens correction capacitors which are well-known for producing crystal clear sound quality. We use TL072 OP (power supply) which is composed of mosfets. Typical class “D” amps use JRC4558, which is composed of transistors only. Mosfet power supplies have a higher speed, lower loss rate, lower noise, and ultimately supply more efficient and clean power along with lower THD (distortion). We redesigned the layout of the PCB boards to allow the amp to run smooth and cool. Each and everything 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 do random inspections of the power 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. This means if for any reason you want to return the amplifier back and get a full refund we will send you a label and take the amp back and give you all your money back. (Amp must be complete along with the box).

Description:

The Rockville RWK41 4 AWG (American Wire Gauge) amp kit has the following differences over other amp kits on the market at this price point.

1. Our RCA cables are 100 % copper. These are top of the line RCA cables

2. Better Resistance: The only thing that really matters with wires is the resistance rating. This is a measurement of conductivity and how much signal is loss per foot of wire. Since Rockville wires are made with around 3 times as much copper as any other wire at this price point, these wires had a much better resistance rating which means they will transfer more power to your amps than the other brands.

3. We do not cheat you on the thickness of the wire. These are standard American wire gauge thickness. This is another reason our conductivity is better than anything else at this price point. Other brands in the market place write 4 gauge, but cheat you on the thickness. We are honest about the thickness.

4. The Rockville amplifier installation kits feature a new soft abrasion proof insulating jacket. This rugged PVC outer jacket allows for 100% improved flexibility over standard power cables making them extremely easy to route through your vehicles interior, and it maintains exceptional resistance to grease and oil. The PVC outer jacket can with-stand an extreme temperature range of -40 to 220 degrees F.

The RCA signal transfer cables included in this kit feature blue and silver twisted pair technology in a clear outer jacket insulation skin. Not only do the blue and silver wires look cool but they also provide superior signal transfer with maximum noise suppression. They are 100% copper to provide absolute lossless perfect signal transfer to your receiver. This technology reduces interference, so your audio signal flows clean and pure at all power levels.

This kit also includes a massive 60 Amp AGU Gold Plated Fuse, so you can be sure it will handle the all the DC power that your amp will need without even the slightest loss of current. The included 7 split loom tube provides protection for your power cable from the typically harsh environment found under the hood of your car.

Audiosavings product experts have tested this amp kit against many leading amp kits on the market and were were impressed not only by the great looks but by the quality of these Rockville installation kits as well. These kits had a lower resistance rating than the other brands we compared and tested them against. What this means is that Rockville manufactures their kits with more copper than other kits at this price point, ultimately providing your amplifiers with better and cleaner DC power, so they work cooler and more efficiently. You will hear the difference a Rockville installation kit will make!
