4" speaker adapter for lateral trim panel rear

E46 4" Speaker Adapter for Coupe/M3 This adapter screws directly into the original speaker pod. The threads are slightly loose, allowing space for Teflon tape. I applied Teflon tape to ensure a secure fit and prevent the speaker from vibrating loose over time. The speaker is fastened with M4 screws, with a little dab of loctite on them. Dry-fit before fastening and verify glass, latch, wiring and trim clearance through full operation.
