• [Installation Safety Specifications]:When setting up your tire-mounted car subwoofer, turn off the vehicle's main power before wiring to avoid short circuits or electric shock; route the power cable and audio cable of the hidden car subwoofer separately (spacing ≥20cm) to reduce signal interference; connect the ground wire to a clean, rust-free chassis ground point (critical for stable performance of the built-in amplifier subwoofer), and keep the enclosure away from high-temperature/flammable areas; secure screws tightly with anti-loose washers to prevent vibration loosening, and reserve ventilation space for the cast-aluminum subwoofer enclosure.
• [Usage, Maintenance & Sound Optimization]:For your spare tire subwoofer, avoid prolonged full-power operation to prevent amplifier overheating; regularly inspect the wiring terminals and mounting screws of the in-car subwoofer, and tighten loose components promptly; keep the enclosed tire subwoofer ventilated and dry to avoid humidity damage to internal audio components; fine-tune bass gain and crossover parameters of the remote-controlled car subwoofer via the wired bass knob to adapt to rock, hip-hop, or classical music styles.
