PHOTO 1 (Refer to the YouTube link above for more detailed instructions). Remove the door trim from the door. If you don't have plastic trim removal tools, you can use a scraper or similar. Make sure you cover the metal tool using some fabric or electrical tape so that you don't damage the paint or plastics.
PHOTO 21 NOTE- this step is only required if the depth of your speaker magnet sits inside the door frame. You can check by holding the door trim, SDP and speaker in position and checking if the magnet is obstructed by the plastic sheet. Cutting the plastic sheet is not required for Focal ISU-165 or ICU-165 speakers. It is required for Focal speakers from the Flax and K2 ranges. If cutting the plastic sheet is required; cut it around the rectangular hole in door frame as shown in the photo.
PHOTO 24 (Skip this step if you did not need to cut the plastic sheet). This step is not compulsory, but is recommended for additional water proofing. We mark on the back of the door trim the approx. size of the hole in the steel door frame and apply a waterproof coating to the back of the door trim + the inside edge of the speaker hole. This is so that the area potentially exposed to rainwater inside the door frame is waterproofed.
PHOTO 27 (Skip this step if you did not need to cut the plastic sheet). Cut a square of the Dynaliner and stick it on around the speaker hole. This will create a seal between the back of the door trim and the door frame. Toyota have used the same concept with the hole for the rectangular door handle (you can see this in the photo above).
PHOTO 31 Hold your speaker in position and check the speaker magnet does not touch the door frame. If it does, you may need to shift the SDP a couple of millimetres toward the rear of the door trim. Important note- once you have the SDP in position, check that it does not touch on the plastic cover at the bottom of the B-pillar.
PHOTO 39 The following 5 steps will be useful if you are installing tweeters in the SDP. The mounting washer is an ideal place to mount the crossover. This position lines up with a large hole in the door frame, so there is plenty of depth available. This position is also waterproof as it is protected by the plastic sheet.
PHOTO 64 Using a 3.5mm drill bit, drill the rear screw hole through the SDP, through the door trim and into the door frame. This hole should be in line with the line in the door trim, and centred between the pocket and the edge of the SDP. This rear mounting point secures the SDP to the steel door frame.
