i have a new pioneer head unit with a new 10" bazooka tube sub in the trunk. i believe the tube is amplified (correct me if i'm wrong) and my speakers are stock. i really dont know how to tinker with the settings for the music and bass to sound good, so if you know what settings should be made higher, lower, louder, softer, etc. please help me out. is what i have not enough to really get good sound? and if not, what should i add/replace? i'm on a budget, so it really cant be anything nuts
