    650 Watts Of Raw Power

    The TH650.1D is a mono block amplifier that is capable of delivering up to 650-watts RMS power into a 1Ω speaker load. This unit features several technologies that have been proven over time to deliver exceptional sound quality. The TH650.1D includes a patent power supply, patented Adaptive Class D design that increases sound quality by eliminating RF interference generated by the MOSFET power supply, and Smart Engage auto turn on technology that eliminates the need to run a remote wire to activate the amplifer during installation saving time and possible damage to the dashboard.

    This model also features a 24dB/oct low pass filter that increases sound quality by reducing unwanted frequencies more effectively, a variable bass boost from 0-12 dB at 40Hz, and a variable subsonic filter for use in vented subwoofer enclosure applications.

    This amp will surprise you. This should drive any 8", just about every 10", and quite a few 12" subs well. Running a 1 ohm stable operation has this amp running barely warm to the touch hours into a play session. Plenty of features and adjustments for anything you should need, included bass control dials in bass level just right, clean sounding power output, compact and clean design, and the level of versatility this amp offers makes it hard to beat.

    Fine Craftmanship

    The TH650.1D also incorporates Intelligent Surface Mount Design Technology which utilizes smaller parts and separates the circuit board into localized zones eliminating interference and improving sound quality. The dual layer circuit board has more copper traces than single sided boards and is able to more efficiently transfer signal across the board with less loss. A clip light is included making it easy to set the amplifier's gain control to the source unit.

    Also available in 1200-Watt and 350-Watt models.
