I was very pleased to find out that SGS actually custom made these mounts to fit the speakers I had purchased. They messaged me after the purchase to ask what speakers I was using, made mounts that fit the speakers perfectly. After I realized my audio upgrade was more work than I wanted to tackle I took it to a local Audio install shop and when I picked up my vehicle I asked how the adapters worked out.. even they said they were perfect! SGS was the only place I could find adapters that I knew were going to work for my Lexus, even though they may have been a little more pricey than another option that may or may not have fit, the service and quality were what came through on this one. I’ve heard the saying in the past, buy once, cry once, which with the quality and service that come with the product purchace here, no need to cry. Hats off to the people at SGS!!! Thanks!
