HHR Ed Posted October 16, 2013 Report Share Posted October 16, 2013 Geeze, 20 off of 1 amp is gonna be a huge headache. performance may not be the best either. But if you had D2 woofer, you can parallel each for 1ohm each woofer Then series 5 woofers together and have 4 groups of 5 at 5ohms each. Then parallel the 4 groups together for a final load of 1.25 ohms nominal. Of course with all those woofers and series wiring, you will rise up very high and efficiency will fall. Any reason you would not want more amps?
