Just joined the forum today and I look foward to getting to know everyone. I just bought a used 2001 Sport Trac with the Sony 6 disc player. I noticed it's kind off lacking on in the bass department. Behind the the drivers side rear seat is a sub and amp. I beleive it's a 7" sub and not sure of the amp Watts? Maybe someone knows. The sub is working but it just doesn't thump. Me being a new owner, I don't really know how good they are suppose to sound. Another quick qustion. Can I just pull the sub out without pulling the whole enclosure out? I tried, but I just don't want to pull too hard. Thanks, Brian
