I am a car subwoofer fanatic! I love subwoofers, and the bass that they produce. With that being said, I wanted to share my opinion and knowledge with everyone else that wants to learn about subs. That's the reason that I created this ebook. I have learned a lot about subwoofers, amplifiers, enclosures, and bass over the last few years, and this ebook explains almost everything that I have learned. It is literally the perfect book for someone that is looking for a subwoofer for their car or for someone that simply loves speakers!
