First post on my part, but I have had my share in car audio money spent and installs. The best 10 inch subwoofer that I have ever heard and had was a Boston G2 10 subwoofer in a slot ported box, however currently in my 05 Yukon Denali I have an Alpine Type R 12 inch subwoofer being pushed by at 1200 watt 2 channel amp using a line out converter from my factory Bose audio amp which I do not lose any base with the increase in volume I am extremely happy with the way it sounds the only thing I'm thinking of doing is changing the box. my best friend has a Tahoe and he has one kicker comp 12 being pushed by a kicker 5 channel amp but he doesn't have bose and I'd say his sounds equally as good if not better than mine only because he's actually put the money into the head unit and the amplifier along with all kicker components throughout. both stereo systems sound great with all varieties of Music so in my opinion its all into what you want to spend and how you want it to sound. sealed box, ported box just do the research and pick the best set up for the money and your ears, after all... That's who is going to enjoy it the most!
