" These rear speaker adapters fit perfectly and made installation of aftermarket speakers quick and easy. I attempted and failed to install these speakers using other mounting methods that just didn't work... I tried a universal adapter from an auto parts store, attempted cutting my own adapters from MDF board, and even tried modifying the cheap OEM speakers to use them as "adapters". All of those attempts failed, I should have simply ordered these adapters from the start, they are a must for a pain-free installation at a great price! " ~ 2004 Acura RSX owner
