A complete bass package with twin drivers, a matched mono amplifier, a wiring kit and a dash remote. It is heavy and large, so plan trunk space and a strong electrical supply.

Overview
Wiring the included kit to the amplifier brings the whole system together: twin subwoofers in an angled quasi transmission line cabinet, carpeted and made of MDF. A dash mount remote adjusts the bass on the fly.
Driver, box, amplifier and wiring arrive together, so there is no matching work beyond installation. The limitation is weight and listing quality, since the item weighs over fifty pounds and several rows, such as the frequency response and input voltage, are clearly wrong.
Who it's for
Car audio fans who want a complete bass system with a dash remote and wiring supplied. Drivers needing a slim box, or a lighter setup for a hatchback, should look at a smaller kit.
Pros and cons
- Complete system in one order
- Angled cabinet for in-car projection
- Dash mount remote included
- Adjustable subsonic and low-pass filters
- Heavy and bulky
- Several listing spec rows are wrong
- Needs trunk space and strong power supply
Performance notes
The cabinet angle projects bass toward the cabin, and the amplifier output at the stated impedance sets how loud the drivers play. Subsonic and low-pass filters trim unwanted extremes, and the wiring kit has to carry the current the amplifier draws.
