Product Description PHF450D MONOBLOCK AMPLIFIERCAR AUDIO FULL RANGE AMP 1.Level Controller： Controls the left and right channels output level 2.Input： The RCA jacks allow for a low level Left and Right channel signal input.Simply connect to the source unit using RCA type audio cables,keeping them away from power wiring wherever possible to reduce riskof noise 3.Remote Leve ： ControlThis port is for the remote level control. The control is intended to allowthe user tothelever of aain up tothe maximum adiustment lever set onthe amplifier. The control does not add additional boost, it onlyattenuates the setting that is fixed at the amplifier’s controi panel. 4.HPF Crossover Adjustment： Use the adiustment to select the crossover point. Remember that youmust adjust the High Pass position(HPF) as the HPF is alwaysengaged. The HPF is limited between 20Hz-20KHz. 5.HPF Crossover Adjustment： Use the adiustment to select the crossover point. Remember that youmust adjust the High Pass position(HPF) as the HPF is alwaysengaged.The HPF is limited between 20Hz-20KHz. 6.Hi Input Connector： High level inputs left and right to connect the amplifier to the radiosspeaker outputs. The amplifier automatically turns on as soon as asignal is received (AUTO TURN ON) 7.Power Input Connections： These connections are for input power, chassis ground, and remote turn-on. 8.Speaker Output Terminals： Connect yours peakers to these terminals. Stereo connections areconnected as labeled. Bridged connections use the LEFT andRIGHT- as the two connections. The mono blocks will run 2 ohmsmono! ONLY. 9.Status LED’s： These lights indicate when the amplifier is powered up normally andwhen there is a protection fault. The Protect LED is laminated whenthere is a problem with your amplifier.

Excess energy is stored until it’s needed instead of being converted into heat. Reduction in size/weight, reduced power waste, smaller heat sink, compact circuitry2-4 Ohm Stable – Able to continuously power loads of 2-4 Ohm without encountering difficulties such as overheating. Typically made to power up subwoofers that demand the heavier power load requirements to be able to perform the way they were made toEngineered to be the most efficient car monoblock amplifier in its class so that you can get the most out of your vehicle’s electrical systemMOSFET pulse width modulated power supply and proprietary heat dissipation design will ensure the amplifier for car subwoofers runs cool for even the most demanding playlists
