I dont see why not. In my truck, they really seemed to help the lower mid range sounds.
and a little acoustic fill in the baffle also seems to bring out the bass a little bit more
I can tell you that there is a difference between the baffle with acoustic fill
and no baffle
I got mine out an 86 T-Bird, the rear speakers have baffles on them. The local Wrecking (Salvage) yard charged me $5 for the pair.
Or was it an 88,, heck I don't remember. I was a T-Bird and they were on the rear speakers
