Mechanical Functions (cont.)

Vents (Side and Rear)

The cooling vents must be kept clear of obstructions once the ampliﬁer is installed. Failure to do this could

lead to premature thermal shutdown or ampliﬁer failure.

Ampliﬁer Linking

The design of the side panels enables multiple ampliﬁers to be used together without additional hardware.

Wire Connection

Ampliﬁer accepts stripped wire directly into the terminal blocks. Speaker outputs accept 8-gauge, and the

DC power and ground accept 4-gauge. Tighten with supplied hex wrenches.

Fuses

Ampliﬁer accepts standard AT-style automotive blade fuses.
