I have a 93 DX hatch and it dont have rear speakers, I think most were like this but not sure, I wanted to get the si bracket kit to throw some speakers in the rear and call it a done job, My question is will a 5 1/4 inch speaker screw into those brackets from the si?? Thanks for all the help guys!!

 

they will be a bit small but yes they will fit, some 6.5s are a tad to large.
