Please do not connect any speaker (-) to the ground or vehicle chassis.
Amplifier - Applications
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 should not be lower than 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.
•
•
INPUT LEVEL
• Turn the INPUT LEVEL control on the amplifier to 5V 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 60 -
100Hz, 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 - 40Hz, depending on the size and response of the Subwoofer.
BASS BOOST
• The BASS BOOST - Control increases the bass level at 45 Hz max. +12dB.
Caution!
Please use the Bass-Boost carefully. The additional boost may result in clipping or overload.

Connect cable from REMOTE CONTROL
with the input jack of the amplifier.
