Just in case someone stumbles onto this thread let me give an update. The planet audio started not turning off with the head unit and would only power down if I yanked the rca's. Next it started whining and then it went poof, smelled like **** and is now a doorstop.
Ended up putting 1 xfl 12 dual 2ohm due to the size of the box on a vfl444801d. I know there are a lot of die hard jl guys around but there is really no debate about this 1 AB12 hits harder then the two 12w3's (which slammed) especially on low notes. The jl's were punchier on real drums like rock country etc but the AB moves way more air and sheet metal! Here's the box if anyone is interested in going AB & the jl box it replaced (almost the same size btw). It is tuned to 32hz and the mofo kills a low note. I metered the amp on a 50hz sine wave and I am giving it about 1600 watts and I swear it wants more..
