ok, before you guys talk down on me. lol, i had some rockwood speakers i think they are model XR-4312, and i had them for like 5 or 6 years. so when i had a car, had an amp and decide to hook them up, i wanted to look up the specs for those speakers. next thing i know, i could not find these subs in the internet at all. and when i do, the detail is just a waste of time and not even worth looking at bcuz there are no enclosure requirement for the subs, no rms rating..etc. justa price, max power, dimension, and just the ohm inpedance. help a brotha out. thanks.
