Nice speakers...but...

Crutchfield Customer Review (What's this?)

I would have rated these 5 stars but they did not come with screws or a template? I sealed up the doors with 1/8" closed cell memory foam and they sound great in the rear doors of my 2003 silverado.

Pros: Great sound

Cons: Does not come with ANY hardware. Just the speakers.

Product Research


Overview: The Boston Acoustics SA746 speakers are special application 4x6 component plate speakers. They include a 4" round woofer and a 3/4" tweeter mounted side-by-side on a rectangular plate. This design combines the imaging and performance of separate component speakers with the drop-in convenience of coaxial speakers.

Tweeter: Each speaker has a 3/4" semi-dome tweeter for a smooth high frequency response and linearity. The tweeters are ferrofluid-cooled to improve durability.

Woofer: The SA746s are equipped with moisture-resistant copolymer woofer cones.
