2. ELECTRICAL WIRING
Attention! Disconnect the negative battery clamp before you start any wiring work!
Main Power Cables
EMPHASER recommends a minimum power cable cross-section of no less than 6mm²
for both the main and the ground power cables. This does guarantee trouble-free operation.
For full power output (for 5m total length) of the amp module, 10mm² power cables should be
used. Cross sections too low will cause the amp module to overheat.
