haha read a few posts down I have a 2011 STI 5-door and I bought the 10 inch 250 watt just to go all out as far as amplified from bazooka. it barely takes up any space in the back and it HITS HARD, I can't see out of my side mirrors at 30 on the radio with the bass a -1 on the radio and the tube knobs at 50%.

I say go for the 250 watt!

also tap into the front speakers not the rear I went through hell until I found out not to use the back speakers.
