So I got a brand new 2013 Civic a few weeks ago, all I'm looking to do is get a Sub and a Amp which is all I really need since the speakers are still new and sound good and the stereo is pretty good as far as I'm concered has bluetooth, usb, aux the works. I'm looking to get a low end system going obviously, something under 200 or around that for everything I would need, I just need some ideas. Just need 1 single sub, and I want it ported. The amp doesnt really matter to me. I just wanna know how much everything would cost for something remotely decent for the 200$ price range out the door. Any ideas?
