Pro Tips

• Start with Moderate Gain: Set the gain control low and increase slowly to avoid distortion and ensure clean bass.

• Crossover Tuning: Begin with the crossover set around the midpoint and adjust by ear to blend seamlessly with your speakers.

• Bass Knob Placement: Mount the remote bass level control within easy reach so you can adjust bass on the fly for different music styles.

• Phase Switch Check: If bass feels weak from your main listening position, flip the phase control — this simple change can improve low-frequency integration.

• Quality Wiring Helps: Using good quality power and ground wiring (recommended gauge) improves performance and system stability.

Perfect For

• Music genres like hip-hop, EDM, rock, and pop

• Seasonal travel or daily commuting sound upgrades
