Additional Notes
- The 1988 BMW 535i uses 4x6 inch speakers in both front kick panel and rear deck lid positions, suggesting a uniform speaker size approach across the factory audio system.
- Full-range speakers are specified for both locations, indicating these units handle the complete frequency spectrum without separate tweeters or dedicated woofers in the factory configuration.
- The kick panel mounting location in front positions may influence imaging and soundstage characteristics differently than traditional door-mounted speakers.
- The rear deck lid placement typically provides fill sound rather than primary audio output, though this depends on cabin acoustics and listening preferences.
- Upgrading to higher-quality 4x6 full-range speakers could improve clarity and tonal balance without requiring modifications to the existing mounting locations.
- The 4x6 size represents a rectangular format that may offer different bass response characteristics compared to round speaker designs of similar surface area.
- Single DIN radio specification indicates standard aftermarket head unit compatibility if source component upgrades are considered alongside speaker replacement.
- Full-range speaker replacements would maintain the factory system architecture while potentially offering improved materials and construction quality.
