I've run 2 Kenwood 12" 400wrms on a 9105d @ 2ohm. That's 900 watts total in a sealed box in the trunk of an '07 Impala. Sound was beautiful once I replaced all the factory with Kenwood 6.5 components and tweeters in front and 5 way 6x9's in the back. As good as the subs sound, its not enough. I've been all over Google, various threads here and elsewhere. I'm pretty set on the ppi 1800.1 for amp. I've narrowed my sub choices to 2 Hds312, 2 Obsidian v3, orC2 Audio. Basically the best bang for your buck price range. Opinions and suggestions.
