INSTALLATION & COMPATIBILITY

The CBA4500.4 is designed for trunk or amplifier-rack installations where adequate space and ventilation are available. Its four-channel layout supports powering full-range speaker systems or bridged configurations for higher-output applications. Due to its Class A/B architecture and high current demand, proper airflow and heavy-gauge power and ground wiring are required for stable operation. This amplifier integrates well with aftermarket head units and signal processors and is best paired with speakers capable of handling elevated RMS power levels.
