If i buy two FI ssd's, they come in two options, 1 ohm or 2 ohm. Im pretty sure i cant wire 2 ohm to one ohm, but can i wire two 1 ohm subs to one ohm?
Yes, the same way you wire two dual 4's to one ohm. With a 1 ohm DVC sub you take the - from one side and route it to the + on the other side. Then you take the +/- from each side and run that to your amp. This will give you a 2 ohm load. Now add another sub (EXACT SAME ONE) to the equation and you will have a 1 ohm final load to the amp. Hope that helps ya.
