Still using two cans. The Add W1 V3.3 actually has TWO inputs into ONE can. TBH, I think two can is probably better (one for each side) but really depends on mounting possibility. I will be curious to see how you set it up as my cans are scheduled to be here this weekend.
Perhaps i will mount one in stinger to start and one in
sorento to start and then decide later if i need to "borrow" the one from the wifes car!!
Only problem there is that i got colored rings to match each paint and they are not the same!!
