Im installing 3 OA 15s . Im planning on having all 3 of them hooked up to a sundown saz-1500. The car has 1 run of knu 0 gauge cca, the big 3 done and an upgraded alt from KNU that gives us 60 more amps over the stock alternator. Im trying to decide between going dual 2 or dual 4 on the woofers. if I choose to go dual 2 on can wire all 3 of them down to a .666 Ohm load. if I go dual 4 i can go down to a 1.33 ohm load. My question is what would you do and why? Also can the saz-1500 handle .666 daily? I know after box rise It will be well over 1 ohm but what do you think? and can the oa 15s handle the saz-1500 at .666?
