Wiring from the amplifier plate to driver unit(s) :
Use the specific woofer cables that are provided with the amplifier module.
(Length 85cm with dual output on woofer side / with 2.8mm (-) and 4.8mm(+) female
terminals) . If necessary, non-used outputs wires can be cut and insulated / if necessary,
output female terminals can be deleted and stripped wires can be welded on driver unit
terminals
Attention, the 4 output male fast-on terminals (4.8mm) of our amplifier module are not
designed for wire soldering (wires with female fast on terminal must be used on this side) .
