my current setup is a 2-JL 10" w3's (4 ohm dvc) and the older fosgate 500*2 channel amp (rated at 766watts). my truck is setup with the amp in the middle and the subs to the sides of the amp. imo my truck sounds great (excellent quality) inside the vechicle but when u get outside the vechicle it's not as loud as i'd like it to be. i am planning on building another box and this time i want the amp to mount to either the floor or the wall (more air space). i am hoping with the extra air space that i can get more sound outta it. i am also considering upgrading some of my components. i was thinking maybe a the kicker 800*2 or a hifonics amp and i am undecided on the subs. i would like to keep my current 8 gague power wire (but will upgrade if nessesary), and i would like to find a excellent sub with around a 6" mounting depth or less. i am also undecided if i should go with 2 10's or 2 12's.
