Description of MM842SVC:

The Premium Upgrade
Tuned for the total sonic accuracy you get in a studio subwoofer, the MM1 Series reconfigures this kind of high-quality deep bass impact for an on-the-go listening experience that totally outperforms your OEM factory setup.

Advanced High-Performance Bass
Every element of the MM1 Series is meticulously engineered for thunderous bass, enhanced sonic detail and ultra-durable construction—Dynamic Balance technology, a high excursion bump stack motor structure, glass fiber formers, multilayered and oversized voice coils, high-temp Conex spiders, a vented pole and basket structure, and integrated fuses.

Ultra-Marine Certified
Featuring an IP56 rating that includes a non-corrosive fiberglass reinforced ABS basket, a water-proof surround, weep holes for proper drainage and a polypropylene cone, you get extra, long-lasting protection—that’s all salt-fog and UV tested.

Patented process that guides material selection through rigorous testing that identifies and cancels out unwanted resonant frequencies.

• 36 Square Foot Roll of Rockmat Sound Dampening Material
• Roller for a perfect installation

The Rockville Rockmat RM36 sound dampening material is a must have for any professional car audio install. This package includes 9 sheets that are each 4 square feet. This gives you a total of 36 square feet. 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. If a product does not specify how much material is being used, you should be very cautious about it! Every manufacturer should know what they put into their products! Also, other products on the market such as GTMAT 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 butyl rubber and aluminum which is the same as many of the more expensive brands out there that sell for twice our price.. We do not cheat our customers. We only make top quality gear over here at Rockville!

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.

We make all our models in 2 color options. You get the choice of black and silver. We decided to also keep the look very clean! We see all these other brands tattooing their logos all over the material. I always thought it looked stupid. So I made sure to keep our Rockmat with a clean look to it.

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!
