If you wish to use the internal crossover to power a driver of specific frequency range, use the "LOWPASS" or "HIGHPASS" settings. use this control to match the outputs of your head unit to the amplifier. Starting with your head unit set at about the 2 o'clock 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.
