Real quick...Is there a speaker, and if there is, can you tell me which one, that will direct fit an 04 WRX with the basic audio setup? (6-disc, front component, no factory sub). I don't want to do ANY, spacing, etc. Is there anything I can just plop in the front (including tweeter) and back? I know my options, if any, will be extremely limited, but I am not too concerned with getting something really high-end anyway. I've tried searching, but no one seems to talk about anything that doesn't need some modification to fit...Please Help!!! Thanks.
