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.

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. the fuse protects the amplifier and your car’s 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.

when used with normal, full range systems, set this switch to “FULL.” 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.

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 car’s electrical system from short

use these controls 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 controls until distortion begins to occur, and reduce slightly from this point.

when one or both of the crossover selector switches is in “low pass” mode, one can set the upper frequency limit for audio program sent to the speakers.

when the one or both of crossover selector switch is in “high pass” mode, one can set the lower frequency limit for audio program sent to the speakers.

this control permits adjustment of the bass level up to an increase of approximately 18 dB in either or both pairs of channels.
