Connecting the Unit
CAUTION
DO NOT install or use this amplifier by wiring speakers rated at 2
Ω (or lower) in parallel to achieve a 1 Ω (or
lower) bridged mode (Diagram B).
Amplifier damage, smoke, and overheating could result from improper bridging. The amplifier surface could
also become hot to the touch and minor burns could result.
To properly install or use a bridged mode and achieve a 2
Ω load, wire two 4 Ω speakers in parallel with Left +
and Right – (Diagram A) or use a single 2
Ω speaker.
In addition, refer to the speaker instruction manual for information on the correct connection procedure.
