A Must Have For A Cleaner and Faster Speaker Replacement
These speaker connector wires worked out great for our speaker replacement project. The front door speaker on our GX470 needed to be replaced and we got the DS18 Pro-x698 which was recommended by many owners as an easy fitting replacement. This was true but the wire connectors needed to be replaced sine the OEM ones were soldered onto the originals and I didn't want to mess with my soldering iron. This wire kit definitely saves time. The Toyota white clips worked fine. The spade clips are different sizes so that they only fit on the intended terminals on the speaker which is nice. The spade terminals do have a very snug fit to prevent things from getting loose over time so that was reassuring. I used heat shrink wrap around the spade connections to prevent moisture and any possible looseness. So far the sound quality is great which I attribute mainly to the speaker but the wires make that happen. There's plenty of wire for most car door applications and they look factory installed. These wires really helped make our project more enjoyable and fast.

Small Part, but It Makes Speaker Upgrades Much Cleaner
Speaker harnesses are one of those little install parts that are absolutely worth buying because they let you avoid cutting into factory wiring. That makes the install cleaner, easier to reverse later, and just more professional overall. Metra is a trusted name for this kind of install accessory, and this is exactly the type of item that saves hassle during an audio upgrade. Pros: ✅ Avoids cutting factory speaker wiring ✅ Makes installs cleaner and easier ✅ Great for aftermarket speaker upgrades ✅ Small part that saves time and frustration Cons: ⚠️ Must confirm exact vehicle compatibility ⚠️ Best when paired with the right speaker adapters and hardware Overall, a smart and worthwhile install accessory.

Right fit for Corolla 2017.
Very simple to use. Comes with a pre-installed female molex connector so you don't need to solder, just plug the ends to the speaker's connectors.

Doesn't fit STI Limited
Purchased this because I was told it fits a 2018 WRX STi door speaker connector. I have a Limited Edition with HK and navigation. DOES NOT FIT. Quality piece and metra is great. But don't get the wrong thing. Thank you.

Will save you so much time, clean install
These adapters worked flawlessly. Sound quality is perfect and because I didn’t have to do any splicing, installation was quick and easy. Do note that this is a 2 pack so you only need to order 1 pack of them to do your front speakers. I accidentally ordered two packs but since I plan to do my rear speakers as well I will keep them on the shelf. If you are upgrading to aftermarket speakers for your Toyota/lexus, this is the way to go!

Works well with being plug and play
Easy plug and play for almost all scenarios may need to splice/replace one side of connection for certain speaker terminal types can't complain you can't expect everyone to use the same thing so it still did what was intended for 👍
