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). Product Details Speaker mounting hole diameter: φ147.5mm (can be installed up to 142mm and 146mm for overseas brands) Baffle thickness: 16.2mm + packing approx. 1mm thick Baffle outer diameter: 167mm Mounting screw hole pitch: 157mm Black packing is attached to the back of the baffle. * Since there are no holes in the screw hole area of the packing, please use a pointed tool to pierce them before use. * Depending on the type of speaker, the hole position may not match, and processing may be required. This product is a general-purpose item, so the buyer 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 improvement store, 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. We will ship via packet post with simple packaging to provide it at a low price.
