Sub was $50 from an Amazon special a few months ago, I think its about 75 normally which still isn't bad since its a fantastic sub. Its a Kenwood KFC-W3011, and I just realized it was 1200 instead of 1500W...still plenty for me. Amp (Boss Audio D1200M Diablo Class D) was $80+shipping, one of the cheapest I could find since I don't care about super high volume. Add in building cost plus time and thats it. I think thats still better than the infinity price-wise if you're willing to do the work. I've heard good things about the Basslink and Infinity is a good brand in general (Kappa series is awesome!). Probably not going to be big and booming though, just a full bottom-end if that is what you're looking for.

One question though, do you still have the stock speakers in your car? And head unit?

I hear ya about the money, I probably should have just gotten new injector nozzles in hindsight....
