Crunch POWER DRIVE with QTD Technology delivers huge power in a cool running efficient heat sink. This Pro Power model features built-in electronic crossovers and high-level inputs. 4000 Watt 2-Channel Car Audio Amplifier.

Pre-Amp Circuitry Low Noise Pre-Amplifier
Maximum low voltage signal from the source unit comes into the amplifier through a low voltage circuit which delivers minimal distortion through the amplification process

Inputs Low voltage RCA Inputs
Highest sound quality connection with quality RCA materials helps prevent interference and minimize distortion in the signal path

High Level Inputs
Easily tie into OEM audio systems that do not offer RCA output to maximize after market amplifier power

Operation Mode
Stereo, Bridged Mono or Stereo/Bridged Mono Simultaneously

Crossover/Signal Shaping Versa-Cross Electronic Crossover
Fully Adjustable 12dB Crossovers

Equalizer Electronic
Fully Adjustable 12dB Crossovers

Class/Topology Class A/B
High sound quality circuit that allows POWER DRIVE to develop high levels of power with minimal distortion

Output Devices Technology SPEED-FET
Exclusive Crunch SPEED-FET MOSFET components are doubled up in Pro Power models to deliver more power. Pro Power designs are critical when running large full range speakers as in a Mobile Pro system set up.

Heat Sink QTD Technology Aluminum
Quick Thermal Dispersion Technology assures additional mass in the aluminum heat sink keeps the amplifier running cool with nearly undetectable distortions during normal music listening.

Power Supply PWM Power Supply
High energy Pulse Width Modulated Power Supply delivers power with minimal impact on the electrical system

Output Connections Nickel Plated
Nickel Plated Brass Connection with terminals allow for secure connection while resisting corrosion

Connections Type Screw Down Connectors
Easy access for hand tool allowing a quick and secure connection

Signal Pass Through Full Range
Allows additional amplifiers to be run from the "output" RCA connections which will minimize the need for additional cables running the length of the vehicle. This can dramatically minimize noise.

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

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!

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.
