Additional Notes

  • The 2003 Lexus GX470 factory audio configuration includes four distinct speaker locations, each serving different frequency ranges in the stock sound system.
  • Front and rear door panels share identical 6.5 inch openings, which can accept either midbass drivers for component setups or full-range speakers for simpler configurations.
  • Overhead positions utilize smaller 3.5 inch openings designated for midrange frequencies, potentially supplementing the door-mounted speakers in the factory configuration.
  • The cargo area provides a 10 inch mounting location specifically designed for subwoofer installation, offering low-frequency reinforcement from the factory.
  • Door panel speakers typically receive priority during upgrades since they handle the majority of audible frequencies and often show the most noticeable improvement when replaced.
  • Component speaker systems might utilize the door locations for dedicated midbass drivers while the overhead positions could theoretically accommodate tweeters, though size constraints apply to the 3.5 inch openings.
  • The existing subwoofer location in the cargo area may limit space for larger aftermarket enclosures, though the 10 inch opening suggests reasonable low-frequency capability from the factory position.
  • Full-range speakers in the door positions would handle wider frequency ranges independently, while midbass drivers would require separate tweeters for high-frequency reproduction.
  • The radio accepts both single DIN and double DIN head units, providing flexibility for aftermarket receiver upgrades that might complement speaker improvements.
