Description

These are speaker adapters for R56 Mini Coopers to mount aftermarket component speakers in the factory front door without modifying your factory speakers. One adapter for the woofer and one for the tweeter. These were modeled around CT Sounds Meso 5.25" Components but can be easily adjusted to fit the actual size of your speakers. The mounting depth of the speaker is 2.6" and clears the window. Speaker adapter cut out diameter is 119mm. Tweeter plate cut out diameter is 52.50mm. You will need to drill holes to mount the speaker to the adapter. 40% infill recommended for strength.
