Made for a really clean factory fit and install. Just had to spin the adapter around till the holes for the speakers would end up being in the correct placement. Even, though being being the door cover. Not going to see if the speakers aren't straight. But, I like to take the time to make things look correct. Then, I marked a spot to run the metra harness adapter. Drilled with a 3/8 drill. Able to run the harness wires close to the factory location. Really impressed by their products. Made for factory like easy install. ... show more

    • Works on Mazda CX-5
Style: Speaker Adapter
Worked perfectly for Morel 6.5” woofers in the front doors of my 2023 Mazda CX5. I applied a strip of sound skin foam around both the top and bottom of the adapter. I also drilled a hole through the side for my speaker wires to connect to the speaker and sealed the gap with some butyl rubber to keep the door seal intact. ... show more

Recently bought a new 2023 Kia Niro EV, the HEV and PHEV all have the same basic body chassis and sizing. The stock audio system is pretty dismal if you don't end up getting the premium Hardon Kardon system. The front doors have 6.5" inch woofers with separate tweeters, the rear door have slightly smaller than 6.5" inch, but can fit 6.5" with a different modified speaker adapter. The Niro uses three screws in their speaker bracket, the stock speaker bracket is also raised off the mounting surface just like this one to give you a little more depth. The front doors are a bit shallow with the windows down they do partially encroach into the speaker space so you definitely want to measure and go with shallow mount speakers or magnets and spider baskets that aren't too wide. There's also door molding parts that encroach into the speaker opening preventing large woofers from fitting. The three mounting brackets tabs on the adapter are in the correct place but the depth where the screws fit is off, so you have to drill the the tabs so the slot is deeper and right up next to the raised ring (see pic). Do that and you're good to go. Otherwise the Metra Universal 6.5" speaker adapter should work once you break away the inner tabs, this adapter also fits the rear doors but you need to drill holes into the three divots in the ring as all the other tabs are useless. This Metra 82-7400 speaker adaptor will NOT work for the back doors as the mounting hole diameter is smaller and nothing lines up, even with modifications. ... show more

    • Excellent speaker adapter for Mazda 6. Make sure to get some speaker tape, too.
Style: Speaker Adapter
I replaced speakers in a 2015 Mazda 6. The original speakers come in a non detachable housing, so this adapter for the new speakers is absolutely necessary! With the Red Wolf speaker wire harness, which I bought separately from Amazon, all I had to do is install the speakers into this adapter, with some sticky speaker tape to fill the small gap between the adapter and the speaker, as well as between the adapter and the car body. Plugged in the included wiring harness and I was done! The most tedious part was taking off the door panels and putting them back one. ... show more

    • May need extra screws
Style: Speaker Adapter
I used theses Metra 82-7400 Speaker Plates to install 6.5 inch speakers in the rear doors of my 2005 Nissan Xterra. The inner tabs need to be broken off before installation. You will also need screws to affix the speaker to the Metra ring.
