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

 

The best way is to follow the diagram in your pioneer HU manual

i'd go with 0 ga. kit, and then 4 to each amp from a fused dist block.
Use 3 good sets of RCA's.

don't cheap out on the install, do it right. Good wire, good connectors, etc., etc.
