Description for Rockville Enclosure:

The RD12 dual sealed speaker box is made in the USA with Grade “A” ¾” MDF wood. This enclosure is made with precision cutting machinery by industry experts that have been making these enclosures in the USA for over 20 years. All Rockville enclosures come with a customized enhanced glue that is unmatched by any other manufacturer. That means that the carpet will stay in place and not rip or tear. The ¾” USA MDF is much stronger then any type of import wood.  This will keep your box performing at an optimal level by not flexing and distorting your woofers. Your woofers will thank you!  EVERY Rockville enclosure is not only glued at all joints but stapled as well. If that wasn’t enough we add a layer of silicon to every seam! This makes your Rockville enclosure rock even more!

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.

RM12-B Includes:

• 4 Sheets of Rockmat Sound Dampening Material (3 square feet per sheet)
• Roller for a perfect installation

The Rockville Rockmat RM12-B sound dampening material is a must have for any professional car audio install. This package includes 4 sheets that are each 3 square feet. This gives you a total of 12 square feet. This is perfect to be used as a door kit to cover all 4 of your doors. We also include everything needed for a quick and easy installation! Our Rockmat will increase how loud your car stereo plays! It also improves bass quality and eliminates those bad rattling and distortion sounds.

Installing Rockmat improves bass quality of the speaker and eliminates those bad rattling and distortion sounds.

Our Rockmat is built to the highest standards in this industry using 100% butyl rubber with a layer of heat resistant aluminum. Butyl rubber is the same material high end speakers surround material is made out of. We use the highest quality pressure-sensitive self-adhesive to make your installation quick and easy. Our model has increased flexibility for an easier and more permanent installation! Our sound dampening product uses 72mil of pure grade aluminum! Most products on the market use 50mil. Our product will absorb sound better than the competition. The other products on the market like most of the GTMAT series for example use a mixture of asphalt in their products. They basically are manufacturing roofing material and calling it sound deadener. Their product will work OK, but not nearly as good as our Rockmat. Our Rockmat is made of 100% butyl rubber and an aluminum heat resistant shield which is the same as many of the more expensive brands out there that sell for twice our price.. We only make top quality gear over here at Rockville! These are comparable to the ONYX series by GTMat. (Only we sell it for the price of their lower series!).

Our Rockmat has an adhesive temperature range of -100F to 300F (-60C to 150C). Our adhesive is top of the line! It will stick for years and years! Each layer of our material reduces unwanted noise 5-8 dB! This is among the best ratings in the industry. Our product works as well or better than other high end brands! We did our testing and research.

Installation Instructions:
Rockmat is a self-adhesive. Stick the Rockmat in your desired area. Rockmat is pressure sensitive so after you apply the material into your desired area; apply pressure to it. That is it! Installation takes only minutes! Please note our Rockmat is also easy to cut into the desired shape you need!

To prove how good our sound dampening material is we will offer a 90 day money back guarantee! If you are not happy with the performance; simply pack it up and we will send you a label and give you a complete refund when it comes back to us!
