Features:

Rockville DESTROYER 12D1 12" Dual 1-Ohm Car Subwoofer
Peak Power Handling: 8000 Watts
Program Power Handling: 4000 Watts
CEA Rated RMS Power Handling: 2000 Watts
Voice Coils are made in the USA! 3” 4-Layer Black Aluminum Voice Coils Wound with Aluminum Wire
USA Voice Coils are hands down The Best in the world
The voice coils are rated to withstand high temperatures of 300-350C
Triple-Stacked 300 Oz Y35 Magnets. (Y35 is the best grade and they will perform better than most 400 oz magnets)
1-Piece Chrome T-Yoke with Stamped Logo (1 piece t-yokes magnetize better and makes excursion (xmax) better as well as increases the BL rating. BL is basically how much power you get out of the motor and is one of the most important ratings
We use the highest grade black glue that handles extremely high temperatures which allows our woofer to handle even more power than they are rated
Cast Aluminum Basket With Black Sanded Finish Makes This Sub Very Efficient And Lighter Weight
Large 8 Gauge Chrome-Plated Binding Post Terminals (These are the best terminals on the market and they won't oxidize)
Black Non-Pressed Paper Cone
Our cones are ultra-stiff. They are thicker and stronger than other subs on the market making our subs able to handle more power than the competition
Extra Thick Foam Surround Provides Incredible Sound Quality With Minimal Distortion
Silver Stitching Cone Reinforces the Cone and Ensures Long Life
Shiny Paper Dustcap (Paper is the best material and can withstand even higher temperatures than polypropylene dustcaps
Impedance: Dual 1-Ohm Voice Coils
Special Custom Rubber Boot Magnet Covers Make the Woofer Look Nice and Protects the Magnet
Rubber Mounting Gasket Makes it Easy To Mount the Subwoofer Air-Tight.

About Rockville Quality Control Procedures:
The Rockville brand stands for Quality, Innovation and Value. We aim to deliver products twice as good as our competitors at a fraction of the cost of famous brands. 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 functions and components are tested for quality. Rockville makes products that are virtually un-breakable! Rockville is one of the only brands in its class to have engineers and technicians test every concept model for weeks or months before starting production. Once production begins, Rockville sends product engineers to the factory to quality control every product. After production is complete Rockville has the head of QC in our overseas office test a certain percentage of all products from the production line a second time to ensure that the quality meets our strict standards. All Rockville products are backed with a hassle free warranty.
