Proper mounting affects heat dissipation, cooling, and stability.
Mount on solid surface, avoid dust, direct sunlight, humidity, water, oil.
Use screws, avoid contact with metal parts to prevent ground loops.
Use double or triple shielded quality RCA cables for audio signals.
Route signal cables away from power/speaker/ignition wires.
Keep cables short; shielded RCA cables should not be cut.
Use recommended cross-section to avoid power loss, distortion, or overheating.
Install main fuse within 30 cm of car battery for +12V power input.
Use same cross-section as +12V cable; ensure good chassis ground contact.
Protect cables from shorting to chassis using rubber grommets.
Disconnect +12V terminal before wiring; connect last.
Disconnect the +12V main power cable from the car battery before any work.
Table of power cable cross-sections and main fuse values for amplifier models.
Step-by-step guide for connecting the amplifier, starting with head-unit off.
Connect head-unit RCA outputs to amplifier RCA inputs.
Use fullrange signals for sub pre-outs; avoid low-pass pre-outs.
Connect the remote lead from the head-unit to the amplifier.
Connect speaker cables to speakers, maintaining polarity. Notes on bridging.
Connect ground cable to chassis or -12V battery pole, ensuring short length and clean contact.
Connect +12V power to battery positive pole last, after checking all other connections.
C209/C409 can be used in Fullrange, Highpass, or Lowpass mode.

Explains Highpass (HPF) and Lowpass (LPF) modes for speakers and subwoofers.
Adjust system crossover frequencies using FILTER FREQ. controls.
Set head unit tone, fader, balance to neutral before adjustment.
The "Loudness" function should be deactivated during adjustments.
Setting HPF for satellites affects mid-bass and power handling.
