i have 2 10" Infinity ref. subs running off my Kicker ZX350.4 amp right now, and 4 Infinity ref. 6X8's just off the head unit(Pioneer DEH-P6800MP). i bought an MTX TC6001 yesterday, and i want to run both my subs off of the MTX, and the speakers off of the Kicker. What would be the best way of doing this? ....also, I 'm using an 8gauge Stinger wiring kit right now, should i upgrade to something like a 4? any help would be greatly appreciated
