Additional Notes
- The 1990 Oldsmobile Toronado uses three different speaker sizes across its audio system, with dashboard speakers being the smallest at 3.5 inches and rear deck speakers being the largest at 6x9 inches.
- Dashboard speakers are limited to full-range types only, while front door panels can accommodate either midbass or full-range speaker configurations.
- Rear deck lid speakers at 6x9 inches may offer the most potential for bass response improvement due to their larger cone area compared to the smaller dashboard and door locations.
- Front door panel speakers at 5.25 inches could be replaced with dedicated midbass drivers to enhance lower frequency reproduction when paired with separate tweeters.
- The single DIN radio opening may limit aftermarket head unit options to standard-depth models or require adapter kits for double DIN installations.
- Full-range speaker compatibility across all locations suggests the factory system likely did not include separate tweeters or crossover networks.
- Upgrading the 6x9 rear deck speakers might provide the most noticeable sound improvement given their larger surface area for moving air.
- The 3.5-inch dashboard speakers may require careful replacement selection to avoid interference with factory mounting brackets or grilles.
