Class D amplifi ers have been around for quite some time, but have been used in limited applications. The new D2 Series of amps come with improved effi ciency and in much smaller package. They are perfect for those factory upgrades or just the modest stereo system limited to space. The D2 brings a faster switching system and higher rail voltage than your typical amplifi er. The results of these two key features are cleanliness and effective power delivery at a minimal cost to the battery system in your car. On top of that, you don’t need a lot of room as they are very slim and compact. Don’t be fooled by it’s compact size, this perfected series of amps will astonish you of the power houses they are. Available in MONO block confi gurations only, stable to 2 ohm, but for convenience, we have supplied a twin speaker terminal for ease of installation when connecting more than one woofer Class D2 Subwoofer amps PWM Power Supply 3 Stage Protection Circuit SMD Technology MIL-Spec Fiberglass Circuit Board True Digital Switching High Rail Voltage 2 Ohm Stable Compact Chassis Full MOSFET Circuitry High Level Input Line Output Bass Boost @ 45Hz +6dB or +12dB 18dB Crossover Centered at 80Hz Class D2 Full Range amp PWM Power Supply 3 Stage Protection Circuit SMD Technology MIL-Spec Fiberglass Circuit Board True Digital Switching High Rail Voltage 2 Ohm Stable (per channel) Compact Chassis Full MOSFET Circuitry High Level Input Line Output Selectable HPF/LPF @ 80Hz crossover
