i have a 2007 subaru impreza 2.0R sedan. want to replace my stock speakers with a good SQ components and a similar SQ coaxial for the back. i have heard good things about DLS RS5A and the Boston Acoustics SE50. my doors are very shallow. their specs shud be good to fit well. Can anyone give me details on sound, durability and loudness? also, where shud i place the tweeter? i have a stock tweeter location on the door handle frame. would that be a good spot? any advice on tweeter location wod be great. Using a pioneer DEH-7400HD HU and a Rockford Fosgate 450.4 .......... already bought a pair of Image Dynamics CTX4 4" coaxials for the rear.
