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.

Complete Dual Subwoofer Enclosure Installation Kit!


  • 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.
