Great quality, had to enlarge speaker opening due to speakers not fitting, had plenty of stock, needed 5.7inchs. Was able to route out. Everything included. Easy install. Deaf Bonce d4s-60 used in application

Fantastic Product and Great Kit

Another great product from Sounds Good Stereo. These are much higher quality than your standard METRA style adapters. These are solid ABS plastic and give your speaker a solid platform to mount to. The kit includes everything you need for a seamless install. I will say the pictures are a bit misleading. The description states “two squares” of sound mat. The picture makes it seem like that’s enough to cover the entire door. With the 6x9 and 6.5 adapters I received 4 - 12x12 squares. Definitely not enough to do the entire door like the photo. I just used them to seal the speaker adapter to the door plus about an inch overhang. Then cut smaller pieces to seal holes in the door that the block of plates didn’t cover. Other than that small miscommunication this kit is fantastic. Definitely invest in the block of plates also. They make a huge difference.
