I listen to alot of different kinds of music and I drive like 2 hours to work each way so I try to mix it up alot and the great thing is I can go from 900-2400 watts by just switching up my batt set up lol... I only have 4 boxes and 2 cars I use to test them out I work alot so I built a sealded and ported box for the 12's and 15's and I kinda just judge them like the challenge was judged all in the same style box... I still need money for 4 recones tho out of the motors //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif the Sig, Brahma MK2, Konaki, and DD 9500B... plus I can never decide if I like SQ over SPL lol and depends how much space I need for that week of work to alot of factors...
