This is a listing for "Aluminum Inner Baffle Boards" that allow the use of some 6.5-inch to 17cm speakers in the current "Jimny" JB and JC series. ■Compatibility Information Jimny JB64W *Front door speakers Jimny Sierra JB74W *Front door speakers Jimny Nomad JC74W *Front door speakers ■Reference Information Speaker compatibility requires checking the number of screw holes, screw hole pitch, recess diameter, frame thickness, etc., but a depth of "≦55mm" is a guideline. ▲Vehicle Wiring Colors Driver's side: Red (+), Yellow (-) Passenger side: White (+), Blue (-) *If you want to install without modifying the vehicle's wiring, please consider the following product. <Amon Audia Speaker Conversion Harness 2076> ■Notes The current Jimny has a very narrow speaker opening in the door's steel plate, so terminal interference and drainage become issues when installing large-diameter speakers. If processing is required, such as the terminals being close to the door's steel plate, the installation instructions for "Alpine AS-KTX-S171OB" are helpful. https://ec.alpine.co.jp/68M23020J92-0_AS-KTX-S171OB.pdf Regarding drainage, make a 5-6mm diameter hole in the door's steel plate so that the inner side of the aluminum base's lower part is covered by about half, creating a drainage path for rainwater. 【Work Procedure】 1. Temporarily fit the aluminum base to the door's steel plate and draw a marking line along the inner circle. 2. Drill a hole at the very bottom (the lowest point in the vertical direction) of the drawn line. 3. After drilling the hole, be sure to apply touch-up paint for rust prevention. ■Set Contents Aluminum base for Jimny: 2 pieces Aluminum baffle for 6.5-inch to 17cm speakers: 2 pieces M4 x 10 Hexagon screws: 8 (for combining the base and baffle) M5 x 16 Hexagon screws: 6 (for fixing to the door's steel plate) M5 x 15 x 2.0 Washers: 6 (for fixing to the door's steel plate) M5 Nuts: 6 (for fixing to the door's steel plate) *Please prepare M4 screws for speaker installation separately. ■Important As this is a processed product, scratches and scuffs that do not affect sound quality are inevitable, so please refrain from purchasing if you are overly concerned.
