I have the Bose Speakers in the rear and they do not work. What would be a good replacement set of speakers/ Any recommendations?

A few people on here have these:

And only great things to say about them.

Myself, I switched to Rockford Fosgates and I love them but they are not perfect. They really need a sub to take the bass off the rear 5.25" so they don't get muddy, but they sound good overall.

or u might consider JBL, because the rear speaker is common dimension 5 1/2"
