Alot of home audio stuff is only stable at like 8 ohms, MAYBE 4. Taking a dual 3 (is it? I forgot) sub and hooking up will either fry or atleast put your home surround system into protect mode. Did this myself awhile ago with dual 4 subs, wired them in parallel (2 ohm load) and hooked it up to the stereo. Once I went above like volume 5 the stereo would just shut off and it got really warm. If you wired the coils in series, (if its a dual 3, thats 6 ohms) then it would work. Just be careful.
