Choosing right wire diameter and connectors
For output connector we recommend using pre-built or professionally wired high quality and heavy
gauge speaker wires. You may use Phoenix blocks for your output connectors.
To prevent the possibility of short-circuits, wrap or insulate exposed loudspeaker cable connectors.
Using the guidelines below, select the appropriate size wire based on the distance between amplifier and
speaker. The wire sizes are given for a 4 Ω load.
NOTE : Custom wiring should only be performed by qualified personnel.
CAUTION : Never use shielded cable for output power wiring
