Im ordering some Audio as i cant live with the standard stuff on long jorneys, What size speakers do i require for back and front of my 2003 wrx blob eye??

 

Funnily enough I was going to ask the same question, Ive just replaced the Head Unit to a Sony which has significantly improved them sound quality, but its still warbles and pops on standard speakers on motorway volumes.

From what I've been able to gather from the SN Search, is that the Front Speakers are 13cm, and the rears are 10cm. Max depth including spacers is around 58mm, and I think I saw someone mention you can use Corsa speaker mounting rings with a slight modification to mount them in the doors.

Soundproofing is apparently a must, but not always the whole door.

Hope this helps a little, I'm sure someone will confirm these are correct, or not.
