Okay so I've heard good things and bad things about Rockville car audio! Three months ago I decided to buy a Rockville car audio set off of eBay for $375 I got two 12-inch Subs 4000 watt amp subwoofer box and all the wiring and I went with the pioneer DVD / CD player head unit and my factory speakers are Bose and let me tell you I gave the subs a two-week break in time and since then I have been banging the **** out of them they are loud and sounds great now it's not a Rockford Fosgate or a different expensive car audio system but for those on a budget this one is loud and cheaper couldn't be happier!
