- The 2018 Subaru Forester factory audio system incorporates three distinct speaker positions, with dashboard tweeters handling high frequencies while door-mounted speakers manage mid and low-range output.
- Front door locations accept 6.5-inch speakers configured as either dedicated midbass drivers or full-range units, depending on whether the factory system retains separate tweeters for high-frequency reproduction.
- Rear door panels mirror the front sizing at 6.5 inches, maintaining consistent midrange response throughout the cabin when paired with compatible midbass or full-range replacement speakers.
- The 1-inch dashboard tweeters typically represent the most challenging upgrade path due to their specialized mounting locations and crossover integration with the factory amplification system.
- Selecting full-range speakers for door positions may eliminate the need for separate tweeter replacements, though this approach could sacrifice the imaging precision that dedicated high-frequency drivers provide.
- Aftermarket midbass speakers in the door locations would likely require functional dashboard tweeters to maintain adequate high-frequency extension across the listening spectrum.
- Component speaker systems with separate woofers and tweeters could potentially utilize the existing dashboard tweeter mounts, though custom fabrication might be necessary depending on aftermarket tweeter dimensions.
- Sound staging improvements often prioritize front door speaker upgrades over rear positions, as forward-mounted drivers contribute more directly to the perceived soundstage location and clarity.
