Interconnect cable checklist:
• Connect the INPUT of the amplifier to the head unit line output with good
quality RCA to RCA cables.
• Connect the Subwoofer with the terminal block (SPEAKER OUTPUT/ - +)
of the amplifier.
• The minimum final speaker impedance must not be below 1 Ohms. Too low
speaker loads result in too high heat dissipation and may cause the amplifier run into
protection.
• Please observe speaker channel and polarity as printed by the speaker
terminal block. Incorrect phasing of the speakers results in total loss of bass response.

Caution
Be careful not to connect speaker (-) to the ground or vehicle chassis.
INPUT LEVEL
• Turn the INPUT LEVEL control on the amplifier to 9V position.
• Turn the head unit volume control to about 80-90% of its full setting.
• Turn the INPUT LEVEL control clockwise until you hear some distortion.
• Then turn back the INPUT LEVEL control slightly until you can hear clean sound.
LOWPASS
• The lowpass filter eliminates the higher frequencies. The recommended crossover frequency ranges between
35 -250Hz, depending on the size and response of the Subwoofer.
SUBSONIC
• The Subsonic filter sets the lower cut-off frequency and protects the Subwoofer from damage. The recommended
subsonic frequency ranges between 15 - 55Hz, depending on the size and response of the Subwoofer.
BASS BOOST
• The BASS BOOST - Control increases the bass level at 45 Hz max. +15dB.
Caution!
Please use the Bass-Boost carefully. The additional boost may result in clipping or overload.
PHASE SHIFT
• Is continously variable from 0 up to 180 degrees.
