Never been into stereos before. But decided to add one into my Galant VR-4. I purchased a Alpine CDA 9887. Im looking to spend about another $1000 on componets and a sub. The car has 2 small speakers in the dash which i would put the tweeters in. The front doors and rear deck are 6 3/4" what would you guys go with for more sound quality over loud bass in that price range.
