Caution
Be careful not to connect speaker (-) to the ground or vehicle chassis.
Interconnect cable checklist:
• Connect the LINE INPUT of the amplifier to the head unit line output with good quality RCA to RCA cables.
• Connect the speakers with the terminal block (SPEAKER OUTPUT/ - LEFT + and - RIGHT +) of the amplifier.
• The minimum final speaker impedance must not be below 2 Ohm per channel. 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.
Low pass
• This eliminates the higher frequencies. Set the crossover-frequency between 50Hz-100Hz, depending on the size of the
installed speakers.
Subsonic
• This eliminates the lowest frequencies and protects the speakers from damage.
Bass EQ
• Allows you to adjust the bass boost from 0dB up to 18dB
Caution!
Please use the Bass-Boost carefully. The additional boost may result in clipping or overload.
Phase
• This allows you to match the Phase 0° to 180°. So you can integrate each subwoofer.
•
Connection for remote
control to adjust subwoofer
from your seat.
