Built for SPL

S65 Series square subwoofers are built to deliver exceptional SPL and the most bass for your buck.

The S6510-44

The S6510-44 is a 10" dual voice coil, 500 watt, 4 ohm square subwoofer built on the MTX tradition of getting more than expected.

The S65 Series

The S65 Series is designed for enthusiasts that want to add extreme bass to their system. With more surface area than a standard round subwoofer and patented corner geometry that increases Xmax, the S6510-44 square subwoofer delivers exceptional volume displacement that translates to exceptional SPL. The woofer features dual layer cooling technology with Spider Plateau Venting technology that utilizes the subs movement to cool it as it plays and a radial ribbed t-yoke dissipates heat away from the voice coil through the back plate, so it doesn't overheat even under intense use.

S65 Series Spider Plateau Venting

This square subwoofer also incorporates Spider Plateau Venting which is a mechanical cooling process that targets cool air at the voice coil and a radial ribbed t-yoke that acts as a heat sink effectively managing the subwoofer temperature for long term performance.

The Rockville RWK21 2 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 2 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 150 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 (1) 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.
