right now i have a 2.1 sound system hooked up to my ps2 and i want more bass for when im playing my games... i looked at the sub in it and its 4 ohms and 75W but its only a 5 1/2" sub i think. what i want to do is get a 12" sub that is 4 ohm and around the same wattage. id like to make the sub box into a chair that i can sit on while playing games. man would that be aweseome! and watching p0rn dvd's with loud bass would be fun too.
