that sub model is alost 5 yrs old dude the new pwh model is the same price with a 3 yr warranty at
http://www.onlinecarstereo.com/CarAudio/ProductDetail.aspx?ProductID=17698 and they require less space and have a much lower f3 than the old e series did.and the pwh 302 dvc 2 ohm model we ran 4 in a 6 cf sealed box off a 2010d amp @1ohm (500 rms to each sub) and broke 145 before major tuning and sounded awesome doing it. I never thought Id say I liked anything mbquart better than the 555 ovals but these are the real deal man. they will run off as little as 200 watts and still slam and they are priced right. your electrical should be fine with a decent battery and the BIG3 maybe an extra hc600 or 800 at the amp.
