does anyone here know the size of the rear speaker for 2003 Lancer O-Z ?

 

its supposedly 6.5 inch but the holes are oversized so you have to make sure that you get speakers that will fit the too-big holes... more like 6 and 3/4ths if you ask me.

 

no you dont need the oversized speakers you can get any 6.5 size speakers and then when u take the originals off ull see the metal bend downwards, so just bend it back so the whole is smaller and then just drill 3 holes for the new speaker and u r set
thats what i did fits absolutely perfect

 

there are ehough manufactured "oversized" 6 1/2 speakers that manual bending the mounts is not nessecery.

get an oversized 6.5.................... do NOT bend any metal you absolutely do not have to.
