Ok, what is the most powerful computer subwoofer system out there?? I read that the Logitech Z-5500 system has a 10 in. sub thats pretty loud. Im pretty unexperienced with home theater systems, but would I be able to hook up a home theater amplifier and 12 in. home subwoofer to my computer??? Or, another thought, can I hook up a home amp to one of my car subs and connect it to the computer (probably not due to the different ohms...??)
