I have an 07 impreza 2.5i and the stock speakers and head unit are horrible. I am looking to get some cheap upgrades from crutchfield to improve my sound and hook my ipod up. This is what I came up with can someone confirm these will work.
Front Speakers-Kicker 07DS600 2-way car speakers For 6-1/2" and 6-3/4" openings at Crutchfield.com
Rear Speakers- Kicker 07DS5250 5-1/4" 2-way car speakers at Crutchfield.com
Head Unit-Jensen BT1611I CD receiver at Crutchfield.com
Also I am unsure as to the exact size of the rear, I know the front is 6 1/2 and I read that someone with an 07 wrx used 5 1/4 in the back so I went by that.
