Scosche SAC656 6.5-6.75” Speaker Adapters Compatible with Select 1988-19 Chrysler, Dodge, Jeep & Plymouth Vehicles – 6 1/2″ to 6 3/4″ Adapter for Car Door Speakers – 1 Pair – See Guide for Vehicle Fit

Please keep in mind that this review is for the adapters and the Hyundai Elantra years 04-06 specifically.These adapters worked perfectly for me on an 06 Elantra EXCEPT for one thing, i had to drill new holes for my 6.75 speakers. I rated this product 4 stars because they did not come with any mounting hardware, not a real big deal but it would have been nice.My project consisted of 6.75 Rockford Fosgate speakers. In order for me to get these brackets to work i had to line them up on the adapter so that the 4 outer holes had enough space to screw on the original hardware from the factory speakers to the door panel. Just simply drilled new holes and everything is working as i intended it. To mount the bracket to the speakers i ended up using pan head screws with nuts, otherwise the speaker would not fit in the door panel hole flush with the mounting hardware from the speakers. Finally i lined under the bracket and the outer edge of the speakers with some 10mm adhesive foam tape to reduce rattling. I also modified the duct on the door panel itself, it looked like the speaker Surround was hitting it so i basically just took some cutting pliers and trimmed off some of the plastic. Also getting the speaker harness inside the door panel was a bit tricky, i ended up getting it in through a hole near the bottom left. *Just as a side note may not be bad idea to re electrical tape some of the wiring, on my car the original electrical tape had started falling off.06 Elantra (XD/XD2) calls for 6.75 in front and 6×9 in rear. In order to mount my Rockford Fosgate 6.75, the steps above would had to be taken, but i believe if i were to have used 6 1/2 speakers then i would not have run into the issues i did. There’s also a very nice guide on the Elantraxd.com Do It Yourself forums where you can make your own brackets, but i did not have the tools to make my own, worth checking out nonetheless.*Another side note, the adapters act as a nice spacer as well. Up to 2.75inch mounting depth speakers may fit with these brackets without hitting the Window glass when it’s rolled down.
