due to the advantage in cone area, you should take him if all setup goes the way it should. the audiobahns would push more air also, which is a good thing
how are you guys competing? with a meter? in-car see who's system is louder? go outside to see how far the bass will reach? anyways, if you have speakers on the rear deck...take them out. it will be louder just a few dB more. but hey, every little thing counts
