Quad Amp Hardware Reference Manual
Heat Dissipation
The external mounting options (Opt3, Opt3A and Opt3B) allow the Quad Amplifier to be installed inside a cabinet, with the Quad Amplifier heat sink mounted external to the cabinet or in an air plenum. In the case of Opt 3B, provide good air circulation, in a plenum, with a minimum airflow across the heat sink of 70 CFM. Cooling should also be based on the whole system cabinet temperature not exceeding 45o C (113o F), as well as providing good airflow across the Quad Amplifier heat sink.
The internal mounting options (Opt4 and Opt4A) are

Multiple Units
When more than one Digital Quad Amplifier is installed in a limited area, such as an electrical box, always mount the amps side by side, and allow 3 inches (8 cm) between amplifiers. Do not stack the Quad Amplifiers.
Vibration
When the Quad Amplifier is installed near a source of excessive vibration install an isolation device underneath the Quad Amplifier.
