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.
