Image DynamicsID8 V.4 D2 8" 350W RMS Dual 2-Ohm ID V.4 Series Subwoofer

They are good budget SQ subs. I modeled them in winisd against infinity kappa 8s, and dayton audio ho 8s. These had higher spl sealed at .35 ft cubed. They seemed to not run out of excursion as quickly as the other two in winisd. They were the cheapest. Im giving them 300 watts each...i have two. The sound quality is good, but they distort quicker than they should based on my modeling. Seems like they can't handle the watts... They claim 250 rms. Im still happy with them. Maybe more capable (higher or true rms) subs would be better paired with my amp but they sound great and pound pretty hard for the money in my hatchback. This sound out of a .35 box per speaker is impressive so im mostly happy with this purchase.
