3.With the SmartSub Integrator in augment mode.
4.With the SmartSub Integrator in crossover mode.
The configuration chosen will determine your required equipment, hookup connections and processor settings. Which system configuration is best for you depends mainly on the capabilities of your main left/right speakers.
