Description: 

Rockville W12K6-D2 12" Subwoofers deliver superior performance and increased power handling with infrasonic bass response surpassing all other woofers in its class. The Rockville K6™ Subwoofers are more than just good looks. They are the complete package.

Rockville K6™ Subwoofers offer some of the clearest, loudest bass around. K6™ Subwoofers feature a newly engineered composite treated pulp paper cone, which is reinforced with Kevlar fibers. The combination delivers the warm but hard-hitting bass that only paper is notorious for while completely eliminates flex and distortion using 360-degree Kevlar dispersion technique. Premium Rockville K6™ Subwoofer technology is built–in-to every facet of the subwoofer beginning with the motor structure. By engineering a high tolerance extended and vented pole piece it allows the K6™ Subwoofer to handle more power and withstand more abuse. In addition the continuous “heat-pump” effect from both spider venting and pole piece venting combine for superior heat dissipation and help to increase the subwoofers low frequency range. The linear progressive-roll Conex spider and heavy-duty steel basket’s perimeter venting guarantee heat dissipation without breakdown. Turn this baby over and you might think you are looking a the exhaust of a modern jet engine. What you are actually seeing is the Rockville unique Aero Vent System, which allows more heated air to pass out of the motor structure while inhaling more cool air from the surrounding atmosphere. Increased vented area = lower operating temperature = increased power handling.

Rockville W12K6-D2 Subwoofers utilize high-temperature, dual voice coils. A ribbed and double laminated foam surround reinforced with Santoprene and double stitched to the cone, provides the cone with added strength and complete control at high excursions. Standard spring-loaded push terminals provide for a quick and secure wire connection. The W12K6-D2 weighs in at 16 pounds. It's a heavy duty subwoofer.

Rockville K6™ subwoofers perform well in both sealed or vented enclosures.

The Rockville W12K6D2 is CEA-2031 compliant and rated with an amazing 800 watts peak and 400 watts RMS. That means you are getting 100% accurate RMS power ratings. These days lots of brands have competitions over how many thousands of watts they can write on the box of their items. The problem is you do not know what you are getting from them. It is easy to print a box that says 3,000 watts Max. Our subwoofers are rated in the same way that other famous brands rate their products. We also feel our manufacturing engineers are the best. The sound quality on our Rockville subs are just amazing. Our engineers who design the subwoofers are all in in the USA and have over 30 years experience manufacturing car audio.

You can feel confident taking a high powered amplifier to these subwoofers. They can handle a ton of abuse!  We actually test our subs with twice the amount of power they are rated at just for fun. These had no issues handling the power and sounding good doing it!

If you are not happy with these, we will call tag them and take them back within 30 days of when you receive them for a full refund. On top of that you get a 1 year exchange warranty for any defects.

If you want the best value in car subwoofers, at the best price, with the best return policies, then we highly recommend these Rockville K6.

Complete Dual Subwoofer Enclosure Installation Kit!

Includes:

• 20 Drywall Wood Screws (Wood screws are the type of screws; the screws are actually made of metal)
• 20 Feet of 14 AWG Blue Speaker Wire
• 4 Spade Terminals

This accessory package includes everything you need to install two subwoofers into an enclosure, and wire your enclosure to your amplifier.  This package is a top of the line accessory package which we put together and tested. 

The drywall wood screws were hand selected by our installation experts because they drill into the enclosure very cleanly, without chipping the enclosure.  The speaker wire is 14 gauge.  This is way better than using 16 gauge.  You can be 100 % sure that your enclosure will have a clean signal to the amplifier with this top of the line speaker wire.  These spade terminals have also been hand selected by our installation experts to make the internal wiring simple, secure, and to run the audio signal cleanly.

Authorized Rockville Dealer!

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. Most other kits are standard CCA (Copper clad aluminum). Those kits are 10 % copper and 90 % aluminum. Our kit is over 30 % copper and the rest aluminum. It is a great combination which will give you great conductivity, a great price point, and great flexibility. We have compared these against 10 other amp kits, and these were the best value by far. The conductivity on these was as good as kits twice the price.

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!

Audiosavings product experts have tested this amp kit against the leading amp kits on the market. Here are the facts from our testing.  The resistance per foot of this kit is extremely low compared to any other amp kit in its range.  The other amp kits we tested it against had resistance ratings that indicated they were an 8 gauge amp kit.  We were more shocked than anyone about these tests, because we used to sell some of those amp kits.  (We now will not sell those any more after learning that they are not up to the quality standards of our installers). The conclusion is that Rockville does a great job manufacturing amp kits while other brands are deceiving consumers.
