Hi, I was reading some of the posts on this site and just wanted to ask for some advice. I orderd a Sherwood RD-6106 surroud sound amp, and JBL N38 speakers for front, with yamaha A-635 bookshelfs for rear, and Klipsch KSW-12 for sub. How should i set my equipment/settings for optimum bass settings? I hear a lot of people saying they got no sound from their sub and im just a bit worried. Thanks a lot
