wiring in series will give you a 4 ohm load if you have the dual 2 ohm model. If you have the dual 4 ohm model then series wiring will give you an 8 ohm load. Check your specs. to see what model you got then go from there. A 8 ohm will give you twice the resistance and half the output of a 4, but it won't hurt nothing
