Product Contents 2 Aluminum baffles 8 Mounting screws Compatible with various overseas speakers such as morel, BLAM, BRAX, focal, and HELIX! This product is a general-purpose item, so it can be installed in most car models if the door allows for a 6.5-inch speaker installation. Recommended for outer baffle conversions! Since it can be installed with M4 screws, unlike wood, it can firmly fix the speaker with strong torque. * It cannot be installed if the door has an oval hole or if the hole in the door is larger than the baffle inner diameter (147.5mm).

This product is a general-purpose item, so the purchaser needs to drill 4 holes for fixing the baffle in each door. * Screws to fix the baffle to the door are not included, so please purchase them at a home center, etc. There are no installation instructions, so please check the speaker size and depth and decide for yourself whether you can install it before purchasing. * Please note that there may be scratches/scuffs/dents due to the imported product, but these are parts that will not be visible after installation.
