Audio & Interior
Reinforced Door Sash Set
Integrated Tweeter Housing / Series 1990—2005
Abstract
A dual-purpose structural upgrade designed to facilitate premium audio integration while rectifying the inherent clip fragility of factory sash covers. This set provides a seamless housing for 52mm tweeter units, maintaining OEM interior textures.
Scope
Includes Left & Right Assemblies
OEM Deficiency Audit
- Modification Decay Factory covers require destructive cutting for tweeter mounting, compromising structural integrity.
- Clip Fatigue Original thermoplastic tabs are prone to fracture during heat-cycle exposure and servicing.
MITA Engineering Solution
- Pre-Configured Mounting Features a 40mm insert optimized for 52mm components (e.g., Focal PS165FSE).
- Reinforced Polymers Proprietary material composition for high-tension mounting points.
- Texture Calibration Leather-grain finish matched to factory NSX interior specifications.
Installation Protocol
01
Extract existing sash covers using a non-marring polymer prying tool.
02
Inspect metal OEM clips. If fatigue is detected, replace with Part: 90615-SK7-003.
03
Transfer clips to reinforced MITA tabs. Align with the primary sash holder mounting points.
04
Apply uniform pressure until the assembly snaps flush with the door frame.

System Constraint: Dimensional Limit
Tweeter diameter must not exceed 52mm. Excess volume applies lateral pressure to the sash housing, which may result in tab failure. Components exceeding this specification void structural warranty.
