I have a 40th X-star that I want to add more bass to. I have a 500/1 JL amp and a pair of 12w3's. I have three options of box placement.
1. Under the observers cushion forward firing into the storage area.
2. In the observers storage area firing towards the starboard or drivers side.
3 In the observers storage area against the wall the amps are mounted to firing towards the port side.
Which is best and why?
Also how much of a difference would it make to use 2 JL six channel amps for the six interior speakers instead of the 1 factory six channel?
