I got 2 Audiobahns 1006W. 10 inch subwoofers. They hit INCREADIBLY hard. I went from kicker C10s with a kicker ZR120 amp ... I think they were rated at 90 watts RMS each. These are rated at 900rms each. It's pretty crazy as to how much power they put out. I got the Audiobahn HC2200 amp running at 1 ohm putting out 1600 watts RMS to the subs that I wired up in parallel. The whole setup including the interior speakers and mounting the amp behind the rear seat, took me probably 10hrs to complete. Everything on the interior looks stock no wires are showing. The trunk still needs work since I got the amp for the interior lying around in there. I got some pics as well. Now I only need to wait for my other set of kappas to come in to put in the back.
