Additional Notes
- The front door panels in the 1995 Porsche 928 accommodate 4-inch midrange speakers, which are designed to handle the middle frequencies of the audio spectrum rather than functioning as full-range drivers.
- Rear door panel locations accept 6.5-inch speakers that can serve either as midbass drivers or full-range units, offering flexibility in component selection based on the desired audio configuration.
- The single DIN radio opening allows for aftermarket head unit upgrades that could provide additional power output and equalization control to better drive replacement speakers.
- Upgrading the rear door speakers might yield more noticeable sound quality improvements given their larger size and ability to reproduce lower frequencies compared to the front midrange units.
- The relatively small 4-inch front speakers may benefit from careful selection of high-sensitivity midrange drivers to maintain adequate volume levels without excessive amplification.
- Component speaker systems with separate tweeters could complement the existing 4-inch midrange locations if tweeter mounting points are available or can be fabricated.
- The combination of 4-inch and 6.5-inch speakers suggests a factory configuration that relied on size differentiation rather than uniform driver sizing across all door positions.
