[QUOTE="clickclickw00t, post: 8096456, member: 644171"] Yea, set the bass setting to 0. that is "normal". I think you really need to read up on car audio and setting AMP gains with a Digital Multimeter. Honestly, I had no idea how to do it about 8 months ago, and then after about 2 hours of reading, and spending $50 on a multimeter, I was able to set my gains properly and have had no problems since. Also, the grinding noise can happen if the cone is misaligned, but if you press down on the middle and it makes no noise it is probably fine. I would definitely do research on proper gain setting. That is the most important part of the connection between your head unit and the subwoofer: how much voltage the amp is getting/gaining. Trust me you won't regret it. Doing it by ear only causes problems down the line. you're gonna need to burn a CD with test tones, and with your volume at about 3/4 of the way, you set your voltage. [/QUOTE]
