The BXX800.4 is an 800 Watt, 4 channel amplifier featuring Super A/B Class™ technology to provide the perfect sound quality design. The T3 (twin turbo toroid) power supply torroids in a Pulse Width Modulated MOSFET power supply assures the car voltage is maximized from battery to Ultra-Fi™ output devices. The rock solid Ultra-Fi™ MOSFET outputs, selected for both balance and output power, keep the power smooth even during demanding peak in the music.

Low Noise Pre-Amplifier Circuitry
Maximum low voltage signal from the source unit comes into the amplifier circuit with minimal distortion

RCA Inputs
Nickel-plated RCA jacks create the most efficient audio connection and resist corrosion

Operation Mode
4 channel operation mode allows either stereo or mono bridged operation

Crossover Type
Variable electronic crossovers allow for complete control of the sound

Electronic Equalizer
Control of amplifier output with on-board electronic crossover to tailor specific frequencies to speakers and subwoofers.

Class / Topology
Super A/B Class proprietary designs use high-speed microprocessors with proprietary D/A conversion algorithms to efficiently control the current consumption. At very high listening levels, this unique hybrid of Super A/B Technology results in lower distortion, higher current efficiencies and less heat than conventional amplifier designs

Output Device Technology
Pro-Fi Output Device Technology. The Ultra-Fi™ MOSFET is designed for music production vs just electronics output power. It produces very musical high power with high efficiency for cooling and minimal distortion

Heat Sink
Classic aluminum Hifonics design to minimize heat build up on the Ultra-Fi output devices

Power Supply
Simpatico coil design. The dual coil Pulse Width Modulated power supply keeps voltage constant through the Ultra-Fi output devices

Output Connections
High temperature impact resistant nickel plated connectors with allen head set screws which allow for secure termination of wire and creates an erosion resistant seal

Connection Type
Molded and Angled. Secure connection for all power, ground and speaker connections. Angled for ease of access while creating a clean wire management profile

LED System Protection Circuitry Diagnostics
Monitor overload and speaker short protection with illuminated indicators on the amplifier end panel

Video for Unboxing RWK41 + RTR172:


The Rockville RWK41 + RTR172 4 AWG (American Wire Gauge) amp kit has the following diferences 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 80 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!

One other last thing worth noting about our kit compared to others. Our kit cosmetically looks the best. It has blue power wire, clear ground wire, and twisted pair RCAs with matching colors. This model includes (2) sets of RCA cables.

The Rockville Difference:

Whenever you see the Rockville shield on a product you know that it has the stamp of approval. While other companies simply import products from China, Rockville manufactures the products in China to lower your cost but do so under American style supervision and quality standards to get you that USA quality that you want!

About Rockville Quality Control Procedures:

The Rockville brand stands for Quality, Innovation and Value. 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 user functions are tested and all internal components are tested for quality. Rockville makes products that are virtually un-breakable! Rockville is one of the only brands in its class to test every concept model for weeks or months before starting production. Once production begins, Rockville sends product engineers to their factory to quality control every line of production. During production every product is tested and on top of that Rockville goes the extra mile and has their high level product engineers do an additional quality control. They test a certain percentage of all products from the production line a second time to ensure that the quality meets their vigorous standards, and to make sure that there is never a batch of products with even a slight problem. All Rockville products are backed with a hassle free warranty, though it is unlikely that you will need to use it.

Great features and great quality make Rockville a great choice.
