The 10s are locked in the box, don't remember impedance. They're bridged and I get a 4ohm load. So I'm sure they're dual 4ohm, I know they're dvc. I'd have to have the coils in series, since the subs are in parallel, to end up with a 4ohm load
Just my thoughts, so check me on that.

the 8"s are single coil 4 ohm


before you offer I'll let you, I'm not too worried about selling the 10"s. so for anything under $150 with the box I'd rather keep them and build a bigger box. I just don't want to open it up if I don't have to
The 8s I have sitting around NEED to go.
