Simple
Nice fit on outside but had to modify hole for proper fit to my 4" mids. Good build. Just need to address some exact fit measures.

Worked great for installing 4" kickers in my '97 Pontiac sunfire GT. Much better than the 4x6.

Speaker adapter plates
This item is feature rich but is not rigid enough to play it's part to ensure that you get the best out of your speakers. It should have been a stiffer compound or it should have been made of metal.

Exactly what I needed
These adaptor plates were perfect for installing a set of speakers that I got for free in my truck. They were very easy to install and only need one corner cut to fit.

Great!
I have a Daewoo Lanos and 4x6 inch speakers sound like s*** when in the rear of a car. So I got these adapters for 4 inch speakers all the way around my car, they fit the speakers perfectly! With the added holes it makes it easy to install them because the Daewoo has weird sized mounting brackets, but the extra holes match up almost perfectly.

Good Product
I purchased this adapter plate for the front and rear speakers in a 93 GMC k1500. I went from 4x6 to 4 inch kenwoods (kfc-1065) and the speakers fit well. Nice product.

Good upgrade
These were definitely thicker and held screw threads tighter than the adapter plates that came with the speakers...
Verified purchase

Scosche SA464
These adapters work great in tight spot due to they are thinner that what normaly comes with a 4x6 or 4 speaker and they match up great for the price and over all quality they are great .
