+1 Luke. Well put...

Have you shopped around yet to come up with anything you like? I actually had a member from TR call me yesterday quoting this thread for some pricing. I thought it was you but he just said he was in the exact same scenario. We basically put together exactly what luke81 just suggested with a closeout JVC H/U, JL Audio Evolution TR 6.5" front components, left factory rear 6X9's, closeout Kicker 12" CVR in a vented prefab box, and a closeout US Amps Xterminator 1600.1. All parts and labor was $745. Any shop here should be able to do something similar to this for you in this price range. Very common setup as you can see.

If you want to hear what this sounds like, his car will be done on Friday by 4pm or so. Not the same model as yours but it will be setup almost identical. Although he bought the last of many closeout pieces we had, there is allot of stuff out there that will still get you out for around $750.
