Want to upgrade speakers in my 05 sti.

what size are they on the front & rear doors.

can anyone through any any info on what to have etc.

dont want to spend alot.

cheers

 

fronts are 5.5" in diameter and the rears are 4" i have fitted Focal 165 K2P components in the front of my MY05 but these speakers aren't cheap and you do have to make an 18mm MDF spacer to accomodate them.Whatever you go for you will need some sort of aftermarket spacer but oin a budget id recommend something like Infinity 6510

 

From previous posts i think its the corsa spacer you can use bud...
