Our take on the Boston Acoustics 746

by John Pollard
Boston Acoustics

Great sounding replacement speakers
Are you looking to replace some old 4"x6" speakers in your ride? Boston Acoustics 746 4"x6" plate speakers offer the performance of separate components without the hassle of installing separate tweeters. Each plate comes equipped with a 3/4" semi-dome poly tweeter, a water resistant 4" poly woofer, and a built-in crossover network that ensures smooth performance.

They're also built to take up to 80 watts RMS, so they'll sound great connected to an external amplifier or an aftermarket receiver. Grilles are not included — factory grilles are appropriate for most installations.

Nice speakers...but...

Written By Anonymous, Sacramento, ca. on Friday, October 05, 2012
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.
