Do you have a model number?

front firing from a 8.5"h x 27.5"w x 8.5"d (all dimensions ID) enclosure, which ports out the back left side to a 8.5"h x 40.5"w x 8.5"d enclosure which in turn is ported through a 7.5"w x 8.5"h opening on the back right side into a 8.5"h x 12.5"w x 8.5"d enclosure that finally ports out to the front through a 4.5"w x 8.5"h opening!
Can you post a sketch? I'm having trouble visualizing this (and isn't 8.6" a tight fit for as 10" driver?

Use a multimeter to measure the DC resistance. It will read approx 6 ohms for an 8 ohm driver and around 3 for a 4 ohm.

If they are 8 ohms, your choices are 4 or 16 ohms. I would run them in parallel for 4 ohms. If they are 4 ohms, wire them in series for 8 ohms.
