So i'm interested in purchasing one 12" BL subwoofer but don't know what to select for the options. It will be going into a 2008 Nissan Altima and being powered by a Clarion DPX1001.2 and the specs are: 250 watts RMS x 2 at 4 ohms 450 watts RMS x 2 at 2 ohms 500 watts RMS x 2 at 1 ohm 1,000 watts RMS at 2 ohms in bridged mode i am just wondering if someone could help me figure out what i would need to select for Hyper Pole, Cooling, Flatwind etc. This would be a daily driver and not spl, and pleas correct me if i'm wrong but would i need a dvc 2 ohm sub wired to 4 ohms and bridging it at the amp would bring it down to 2 ohms right? need anymore information, just let me know thanks a lot everyone who replies
