whitch sub should i get out of these choices
i am looking to upgrade my system for my truck. i was looking on getting some kickers. first one is Kicker CompVT 07CVT122. its a 12 inch pushing 400rms and 800 max power. second is Kicker CompVR 07CVR124. same power but i guess it takes up more room then the first one that is a shallow sub. would a shallow sub be the same loudness then the 2 one? it it better to get a 4 ohm or a 2 ohm sub. the first one is 169 the 2 one is 149 in price. any other questions just ask ill try to answer the best i can. thanks for the options in advance.
