If you have the electrical' date=' why not go with 2 crescendo 3k's. 1 amp per 3 W7's.
6 12's with that much displacement and on 6krms will get loud. No way to avoid it. True, JL W7 efficiency is not extremely high. But they will sound good and be able to dig very low.
If this is "daily bump" then i'd hate to see you in competition mode.
For most, daily bump is anything from a few 8's to 18's or at most a 21" occasionally.
As for your charging system plans, the double alt idea will be a must. And I would consider more than one Batcap, even of that size. Multiple runs of 0 gauge will be needed. Don't forget the small stuff //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif[/quote']
Thanks I'm really hoping I can get the custom alt bracket built for cheap and I will do the multilple runs as well. Thanks
