also what size alt and batts should i get??

i thought about getting a 200-250 amp iraggi alt and 3 batts and do the big three...sound good??

because you're box is in the bed of your truck you can build a larger box. that gives you the opportunity to use an amp like the 3500D and get a lot of output from those btl's due to the efficiency of your enclosure (not to mention the high efficiency of the btl itself). additionally, with less current draw you will save $$$ on your electrical upgrades as well. my .02

ah i see lol well when it comes to boxes i have no idea where to even think about startin...thats one thing i kno very very little ablout..
