I have a mono block amp but it has two speaker outputs. If i were too hook up 2 subs each 2 ohm would the amp be putting out 2ohms to each or 4ohms to each.
It depends if your subs are dual (dvc) or single voice coil (svc). I am almost positive they are dual (i dont think there are SVC 2ohm subs in production.. only 4 and 8ohm)
So if they were dual wiring them in parallel would produce a .5 load.. wiring in series would equal a 2ohm load.
Unless you got a very expensive high current amp or modded amp. You wont want to wire in parallel.
