Additional Notes
- The 1987 Pontiac 6000 dashboard positions accommodate 4x6 inch speakers, which represent one of the smaller factory openings typically used in period automotive installations and may benefit from replacement to address degradation in paper cones and foam surrounds common to speakers of this era.
- Full-range speakers are specified for both dashboard and rear deck locations, indicating the factory audio design relied on single-driver solutions rather than component systems with separate tweeters and woofers for frequency reproduction.
- The rear deck lid uses 6x9 inch openings, which provide substantially more cone area than the dashboard speakers and generally serve as the primary low-frequency output in this configuration due to their larger radiating surface.
- Replacing the rear 6x9 speakers could yield more noticeable bass response improvements compared to dashboard upgrades, as the larger format allows greater air displacement and typically handles lower frequencies more effectively in full-range applications.
- The single DIN radio opening suggests limited factory head unit features, which may constrain overall system performance regardless of speaker upgrades unless the source unit is also addressed to provide adequate power and signal quality.
- Aftermarket 4x6 speakers often include polypropylene or treated paper cones with rubber surrounds that resist environmental deterioration better than original equipment materials, potentially extending service life in the dashboard environment.
- The full-range designation means replacement speakers need to handle the entire audible spectrum without crossover support, making sensitivity ratings and frequency response curves relevant selection criteria for maintaining adequate volume levels with factory amplification.
