$500 That's really tight, and with a shop install unless you know the owner really well, your not going to get the whole system and install for that. Depending on what size your front speakers are.

All Pioneer items. I feel they are a good well made product for your budget. I am also just using said store to show what  you can get these items at for your money I could care less where you shop but it dose give you a price range.

6 1/2 2 way speakers $50.
