6 subs

This is what I wrote to you in your thread of two days ago:

When you get into large numbers of subs to figure out, use the Parallel and Series Calculators for help.  Start by figuring the impedance of each sub after wiring the coils;  in this case it will either be 2 ohms or 8 ohms.  Use the calculators to enter that number eight times.  Click the = for the result.

The statement still applies today...only now it's six subs.   You should know this stuff by now, wrathchild.

Divide and conquer.

Be fruitful and multiply.

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.
