I am planning on updating my factory speakers real soon and would like some advice. The guy at best buy said I have 4x6s in the back and 5 1/4 in the front w/ 3" tweeters above them. I have some pioneer 2-way 5 1/4s I bought on clearance for $20, but can return them if they aren't any good. I have been looking around and see alot of pics of what looks like bigger (maybe 6x9s) in the back and maybe 6 1/2 and 5 1/4s and a small tweeter in the front doors. Would it be easy to make that many speakers fit in the front door? What about using a 6 1/2 component kit in the front, and 4x6s in the back. I don't want to half ass it, and want it to sound real good. I currently have a pioneer 7300 7" indash head unit, JL 500/1 amp, and 2 JL 10w0s in custom boxes. Thanks for the help.
