Description:

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

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 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!
