i have an 07 wrx tr. i bought alpine type r 5 1/4 speakers for the rear doors. i knew i would have to modify the doors alittle to get them to work. well i made the hole alittle bigger because it didnt need alot to make it big enought for the speaker to fit. when i went to put the door panel back on it didnt fit because the panel hit the speaker. i dont want to cut the door panel and i want to keep my system the same brand. also they sound pretty nice to. so my fix to this is to make a thin spacer and put the speaker on the inside of the door in the stock location. does anyone think it will effect the sound of the speaker. i dont think it will but i wanted some opinions.
