if you were me... and you have a 6X4 speaker you really wanted to put into the tib's 5X5 holes... how would you go about doing so?

 

Well let's see.The Tib's (GEN1 and GEN2) factory door size is 6.75" and the quater panels are 6 X 9". I would not bother trying to mess with a 4 X 6.They normally aren't very good speakers and you won't have d!ck for mid bass.If you are really hard pressed to use them, I'd use them for rear speakers.I'd disconnect the quater panel location and put the 4 X 6's in the hatch cover.Do alittle custom work and cut some holes in there.Technically, it's best to have rear speakers placed as far to the rear as possible anyway.
