Crutchfield Customer Review (What's this?)

These are a fantastic product in order to adapt round speakers into a automotive factory mount for normally sized 4x6 speakers.

Pros: Universal. All auto manufacturers use different adapters, and hole alignments. These fit the need perfectly

Cons: None, easy and versatile.

Great devices

Great item had to drill to fit my speakers and vehicle but awesome all the same.

Pros: Durable plastic and handled the drilling for new holes easily

Cons: Could have holes pre drilled

They do what they are supposed to

Crutchfield Customer Review (What's this?)

I ordered these on accident, needed 4" adapter but these were right above them in the product list and I didn't pay attention to the description. They are straight forward to use and will work if you have 3.5" speakers to fit in a 4x6 opening. If you're a dope like me and you have 4" speakers, get the scoshe adapters. I have used these metra adapters before, on my last Sierra in the extended cab doors, and they do what they are designed to do and come with all hardware you may need. They don't come with instructions but honestly you shouldn't need them. Have a drill handy as you will most likely need to drill holes on the vehicle panel to mount these, then speaker screws right onto adapter.

Pros: Easy to install (may need to drill)

Cons: None
