I wasn't really planning on subs. Is there anything I can do about the 6x9's?
You should plan on subs, you will never want to go back to a car without subs once you have heard one with them. Im sure you can find a fairly cheap sub(s) on your local classifieds. I got 2 10's with a 400 watt amp for 120$ and thats more bass then id ever want.
