Alpine KTA-200M Mono Power Pack Amp with Alpine SWT-12S4 12" Loaded Tube Subwoofer and Bass Knob - This bundle includes an Alpine KTA-200M Mono 400-Watt Power Pack Amplifier, an Alpine SWT-12S4 1500W Max (300W RMS) Single 12" Sealed Subwoofer Tube Enclosure, and an Alpine RUX-KNOB.2 

Alpine KTA-200M Compact 200 watts RMS Class D Monoblock Power Pack Amplifier

The KTA-200M fits in the open space behind Alpine’s iLX-W650 7-inch Mmech-Less (no CD/ DVD) Audio/Video receiver to create Alpine’s unique Power Stack application. The amplifier's compact footprint (7-inch W x 1.5-inch H x 3.5-inch D) and the iLX-W650's shallow chassis (1.9-inch D) occupy the same depth as a traditional 2-DIN chassis, resulting in an easy, hideaway bass solution that adds more power to the sound system without taking up space.
