Precautions
- Connection Safety: Keep speaker wires away from sharp edges and avoid pinching by trunk lid or moving parts. If no factory holes exist, drill carefully and protect wires with rubber grommets.
- Installation: Use provided mounting hardware and ensure a secure, stable fit without obstructing vehicle functions.
- Electrical: Use proper gauge wires with correct polarity. Ensure all connections are tight and inspect regularly.
- Wire Protection: All drilled holes must have rubber grommets for wire protection. Check wires for wear periodically.
- Placement: Adjust position for optimal bass response and balanced sound.
- Maintenance: Inspect regularly. Disconnect power if you notice distortion or unusual noises.
Wiring Configuration
HED slim subwoofers feature dual 2Ω or 4Ω voice coils. It is essential that both coils be connected to an amplification source. When the dual 2Ω voice coils are wired in parallel, they present a 1Ω load to the amplifier, while wiring them in series results in a 4Ω load. Similarly, for the dual 4Ω voice coils, a parallel connection yields a 2Ω load, and a series connection provides an 8Ω load. Make certain that your source unit or amplifier is rated for the appropriate ohm load to ensure proper operation.
Series Wiring:
- Dual 2Ω Voice Coils = 4Ω Load
- Dual 4Ω Voice Coils = 8Ω Load
Parallel Wiring:
- Dual 2Ω Voice Coils = 1Ω Load
- Dual 4Ω Voice Coils = 2Ω Load
Diagrams illustrate series and parallel wiring configurations for dual voice coil subwoofers.
