crackling aftermarket car speakers

The standard configuration in my car is 2x woofers in the front and 2x woofers in the back. There are also separate tweeters, but it doesn't matter, I won't touch them.
The woofers in the back are blown and in their place I connected BOSE mid-range speakers, which are quite bad to hear (buzzing, crackling... as soon as the volume reaches 45%)

Can I insert only woofers in that place or is there some way to leave these mid range speakers? Im guessing that the car sends low frequencies and they are made for medium. How to solve that?

When I connect the BOSE midrange speakers to my ONKYO mini stereo, everything sounds as it should...
