ok guys changed my choices from my previous thread and narrowed it down to either two SSA DCON-12 S4 subs 300 watts RMS each, or two Sundown Audio E12 (E Series) Subs 400 RMS each. Reason for these choices are that they are in my new narrowed price range of approx $130 bucks each.Which pair would be louder with a good amount of SQ. Either pair would be set to a total load of 2 ohms on a kicker ZX750.1 amp pushing 944 Watts RMS at 2 ohms.Thanks
