input level control use this control to match the outputs of your head unit to the amplifier. Starting with your head unit set at about the 2 oclock position, increase the amp level control until distortion begins to occur, and reduce slightly from this point. low level inputs this amp features gold-plated RCA input jacks for high impedance input. Use these with car stereo output which uses RCA-type connector cables. high level inputs if your car stereo lacks RCA-type output jacks, you may connect speaker output leads to these input connectors. power LED this indicator is illuminated when power is applied. power fuse the fuse protects the amplifier and your cars electrical system from short circuit conditions. power terminals use these connectors to deliver power, ground and remote turn-on control to the amplifier. speaker connections these terminals are 14K gold plated to guarantee high conductivity and minimum signal loss.

Starting with your head unit set at about the 2 oclock position, increase the amp level control until distortion begins to occur, and reduce slightly from this point. when the crossover selector switch is in low pass mode, this control sets the upper frequency limit for audio program sent to the speakers. when the crossover selector switch is in high pass mode, this control sets the lower frequency limit for audio program sent to the speakers. Plug in the Remote Bass Boost Control wire in here. this control permits adjustment of the bass level up to an increase of approximately 18 dB. this amp features gold-plated RCA input jacks for high impedance input. Use these with car stereo output which uses RCA-type connector cables. if your car stereo lacks RCA-type output jacks, you may connect speaker output leads to these input connectors. this indicator is illuminated when power is applied. this indicator is illuminated when built-in protection circuitry is activated. the fuse protects the amplifier and your cars electrical system from short circuit conditions. use these connectors to deliver power, ground and remote turn-on control to the amplifier. these terminals are 14K gold plated to guarantee high conductivity and minimum signal loss. input level control
