•

Do not install or use this amplifier by wiring

speakers rated at 4

(or lower) in parallel to

achieve a 2

(or lower) bridged mode (Dia-

gram B).

Am pi ifier damage, smoke, and overheating

could result from improper bridging. The am-

plifier surface could also become hot to the

touch and minor burns could result.

To properly install or use a bridged mode and

achieve a 4[2 load, wire two

speakers in

parallel with Left® and Right

(Diagram A)

or use a single 4D speaker.

In addition, refer to the speaker i nstruct1on

manual for information on the correct con nec-

tion procedure.
