CEA Compliant Legitimate Power Ratings!

Peak Power = Amount of power the sub can handle for a burst during the loudest point during a song. This number is not as important as the RMS power. This subwoofer has 1,200 watts peak which is a lot of power for a small 8" subwoofer.

Program RMS Power = The Program RMS power the way most middle of the road brands on the market rate their products. This sub can handle 600 watts program power. So for example a 600 watt Program RMS Hifonics amplifier will work perfectly with one of these.

CEA Rated Power = This is an official tested rating by a specific industry standard. This is the way the top brands in the industry such as Kicker, Rockford, etc rate their items. This subwoofer is 350 watts RMS CEA rated. This rating is measured at a very specific distortion level. You can feel confident matching this with a high end amplifier from Kicker, or Rockford, or any other high end brand that uses CEA compliant ratings.

We supply all 3 ratings so that you can compare prices of our product to any brand on the market and also so you can confidently match this subwoofer to amplifiers from many other brands.

Utilizing a sophisticated “High-BL” motor structure together with a large-diameter, progressive-roll spider provides increased linearity and superior overall sound quality. A vented core magnet motor structure with extra thick back & top plates allows for full voice-coil extended peak-to-peak excursion, creating ultra deep bass response. Engineered with a special aluminum alloy high-temperature voice coil winding around the high-mass vented pole piece, helps to keep the woofers cool even when your music gets “hot”!

The Rockville W8K7-D2 is CEA-2031 compliant and rated with an amazing 1200 watts peak and 300 watts CEA 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 2,000 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.

Description:

The Rockville RWK81 8 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 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!

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.
