"I used this adapter to extend my subwoofer connections in my Mustang. It required some cutting and stripping, but overall, it worked exactly as I needed it to."

"I replaced my factory oval speakers on my 2018 Silverado. They fit great and feel solid."

"These worked perfectly for my 2015 GMC Sierra Crew Cab. They fit just like the factory ones; just needed to secure the bottom for a tighter fit."

"I found these brackets to be the right choice for my 2015 2500HD. However, I had to get creative with the installation due to some alignment issues. I added some foam and used extra screws to prevent rattling."

“I found these brackets to be perfectly fitting. Using side cutters, I removed the smaller tabs easily, and with a file, they turned out great. Just watch out for the ear on the side that might interfere with the door card, but that's easy to fix. Overall, I fully recommend these at this price.”

“These worked wonderfully for my 2011 Silverado. The installation of the aftermarket speakers was a breeze, and they fit great. I appreciate how easy it was.”

“While I had to do a little cutting for my Pioneer 651 pro speakers, the brackets fit well after the modifications. They are designed with two sizes in mind, so just be prepared to adjust for the 6.5-inch setup.”

"I found this harness to be easy to install and it worked perfectly for my 1994 Chevy K1500. Just a heads-up, the spade connectors have some unique sizes."

"Using this harness made it super simple to connect my aftermarket speakers. It was a straightforward plug and play with the factory harness."

"This product was functional and compatible for connecting my Kike brand speakers to my 1998 Chevrolet truck. Overall, I’m satisfied with it!"

"I found these incredibly easy to use for my 2014 Chevy Spark. I bought two sets, and they worked amazingly with my upgraded kicker speakers. Just had to bend the plastic clip a bit, and they fit perfectly."

"These harnesses worked great for my 1994 Nissan Hardbody. The fit was perfect, and I was really pleased with the quality."

"I had no issues with these in my 1991 Miata. The spade connectors were a nice tight fit and perfectly matched the polarity. I appreciate not having to cut into the stock wiring."

"I found this to be a very good quality speaker adapter. It offers different mounting options for various speakers, and I'm very happy with my purchase."

"I used these adapters to install a pair of 6.5” JBL GX602's in my 2015 GMC Sierra's front doors. They fit perfectly, but after tightening the screws, the mounts felt a bit wobbly. I used some foam from my speaker box to resolve the issue, and overall, I'm satisfied with my purchase."

"I ordered this product because it claimed to fit my car, but it absolutely does not fit. Unfortunately, the window for returns is now closed."

"I was hesitant to make an ABS plate for my 2013 Silverado, but these adapters fit my Image Dynamics CXS 64s perfectly. Just a heads up, if your speakers are heavy, it’s wise to add some extra screws or rivets since there's only one screw provided. I also used NVX sound deadener and Stinger fast rings for better sound direction. One thing to note is that these don’t fit the rear doors of my extended cab because the speakers there are a different size and shape."

"For my 2011 Chevy Malibu, these brackets worked like a charm. They fit snugly without any rattling. I did have to pick up some #8 x 5/8 inch metal screws to secure the speakers to the mount, but aside from that, it was an ideal solution!"

"I own a 2005 Chevrolet Cobalt, and I was aware that no speaker adapter was available for my model. After some research, I decided to try these adapters. They aligned perfectly with the holes, but the adapter didn’t fit in the door. A quick cut with a Sawzall on one side of the bracket did the trick, and everything fit well afterward. The speaker stabilized the bracket nicely, and honestly, who cares what it looks like since it's hidden!"

"I was uncertain about this speaker adapter. After searching online for confirmation on its compatibility with my 06 Mini Cooper, I decided to buy it and see for myself. It fits perfectly! Installation was straightforward, and no soldering was needed."

"I used this in my 1997 Mitsubishi 3000GT for the door speakers, and it worked perfectly!"

"The install tech recommended this part for my Sequoia, but on the installation day, he said it wasn’t necessary. I was disappointed I couldn’t return it since it was unopened and within 30 days. The product itself is fine, just not useful for me. At least it was affordable."

"I just finished installing 600 of these connectors and I was pleasantly surprised by their performance. Despite my initial worries due to the low cost, I experienced no failures even in cold weather conditions."

"I used these butt end connectors for my car stereo installation and they worked brilliantly! Having the right crimping tool made all the difference. While they aren't as durable as soldering, they are definitely better than other options."

"These connectors were perfect for my second stereo installation in my Xterra. I noticed an improvement in sound quality compared to the stock head unit, and I would definitely buy them again!"

“I used this connector in my 2006 Jeep Grand Cherokee with the Boston acoustics system. I just had to press it really hard to fit the current connector. I believe it works for any Chrysler model with a similar sound system.”

“For my 2005 Dodge Neon, I reached out to Metra for advice on a speaker harness adapter. They recommended this part. Although it wasn’t the exact match, I made some adjustments by shaving a bit off the connector, and it fit perfectly after a firm push. It seems suitable for 2003-2005 Dodge Neon dash speakers.”

“I installed this in my 1990 RX-7, and it worked well for both the in-dash and rear pillar speakers. However, the door speakers require a different connector. I had to grind down the speaker terminal tabs because the spade connectors were too small, but the plastic connector fit seamlessly with the original harness.”
