Features & Benefits
| Compatible Vehicle Fitment | Universal |
|---|---|
| Low Noise Preamplifier Circuit | Maximum low voltage signal from the source unit comes into the amplifier circuit with minimal distortion. |
| RCA Inputs | Nickel plated high temperature impact resistant that allow for secure connections and is erosion resistant. |
| Operation Mode | Five Channel, Full Range, Bridgeable, Mono: Flexible installation allows this amplifier to run in four channel or bridged mono mode. |
| Crossover Type | Onboard electronic crossover |
| Electronic Equalizer | Control of amplifier output with on-board electronic crossover to tailor specific frequencies to speakers and subwoofers. |
| Class / Topology | Class D: High efficiency with big power in a small footprint. |
| Output Device Technology | PWM MOSFET Power Supply: Stable power through the PC board with minimal heat generation. |
| Heat Sink | Aluminum: Modern Design Hifonics Heat sink for Superior Heat Dissipation. |
| Power Supply | Simpatico Coil Design: The dual coil Pulse Width Modulated power supply keeps voltage constant through the Ultra-Fi output devices. |
| Connection Type | Secure molded connection terminal for all Power, Ground and Speaker connections. Angled for ease of access while creating a clean wire mangement profile. |
| LED System Protection Circuitry Diagnostics | Monitor overload and speaker short protection with illuminated indicators on the amplifier end panel. |
| Bass Remote Included | Yes |
| Auto Turn-On | DC SIGNAL SENSE: The DC SIGNAL SENSE switch will allow the amp to turn on when a signal is received on the RCA inputs, so an amplifier remote turn on wire is not needed to turn on the amplifier. This feature can also be turned off. |
