Aerpro APS346 are rear door speaker spacer adapters designed specifically to suit Mercedes E-Class W210 (2000-2002) vehicles. Supplied as a pair, they are designed to suit the rear doors of the vehicle and will line up with the original mounting holes, allowing you to install aftermarket speakers with ease - no door modifications required. They are also slim enough to allow the factory door trim to be placed back on the door, allowing you to keep a factory look interior inside the vehicle. APS346 provide a mounting depth of 19mm and are suitable for 5" (130mm) aftermarket speakers. If you are looking to upgrade the speakers in your vehicle you can't go past Aerpro Vehicle Specific Speaker Spacer Adapters.
