How to install Bosch Indoor/Outdoor Surface Mount Woofer

• Plan your installation – Select a mounting location that provides unobstructed bass radiators and safe access to wiring. Consider coverage area, sightlines, and practical cable routing to minimize runs and impedance losses.
• Prepare the mounting surface – Use appropriate hardware and mounting brackets suitable for walls or ceilings. Ensure the surface can support the woofer’s weight and vibration, and seal any gaps to preserve weather resistance when installed outdoors.
• Wiring and impedance – Run speaker wires from your amplifier to the woofer, observing correct polarity (+/−). The 8 Ohm impedance helps balance power delivery and allows multiple units to be combined for larger deployments; verify amplifier settings to avoid clipping and ensure optimal headroom.
• Seal for outdoors – If installing outdoors, install IP65 port-plugs to seal any ports and protect internal components from moisture and dust. Double-check seals and gaskets after mounting to maintain weather-tight performance.
• Testing and tuning – Power on the system and test with a track that spans the bass range. Use proper crossover settings to blend with any satellite speakers and adjust level controls to achieve even, distortion-free bass across the listening area.
