Buying Guide: Key Considerations When Choosing Side Car Speakers
- Power handling and impedance: Align RMS power with your head unit or amplifier to avoid distortion. Common choices are 4-ohm impedance for broad compatibility.
- Size and mounting depth: Most 6.5″ speakers fit most door panels, but verify mounting depth and hole patterns to avoid clearance issues.
- Coaxial vs. component: Coaxial speakers are simpler to install and compact; component systems offer improved imaging and accuracy but require more wiring and mounting space.
- Tweeter performance: Silk dome or PEI tweeters provide smoother highs. Some units include tweeter level adjustment for sound tuning on the fly.
- Sound signature and room: For quieter cars, prioritize clarity and midrange; for louder environments, aim for higher sensitivity and stronger bass extension.
- Installation approach: Some models include grilles and easy-connect terminals, which streamline replacement and protect the speakers during use.
- Durability: Look for rubber surrounds and sturdy cone materials to withstand temperature and road conditions over time.
