So far I've spent about 700 on all of this:
-Clarion deck ($150)
-5x7 Eclipse speakers ($150)
-10 inch MB Quart sub ($170)
-250 watt Rockford Fosgate amp ($180)
I guess that is only 650. All I really want to do now is replace the speakers in the back of my car for another $150, and possibly get a CD changer for like $200 more. About a 1000 dollars in all. I can't imagine what else I would do with $2,500. Probably would have bought a much more powerful sub and amp and would run the speakers in the front through an amp. I also would have bought a nicer deck. Even then, it would be hard to get up to $2,500. I guess I would hit Vegas too.
