Driver wiring options

This page looks at the various possibilities for connecting multiple 4ohm drivers.
Stereo solutions that produce a load less than two ohms per channel or greater than eight ohms per channel are ignored
Mono / Bridged mode solutions that produce a load less four ohms mono are ignored
When using pro amps, the stereo solution produces lower distortion than the bridged solution
The preferred solution is drawn in stronger colors. It's the one that provides sufficient power without stressing the amp
After the drawings is an analysis of what power would be available using the Behringer amps, and the preferred option is shown

 

IB4 - Four driver system
Requires 190w normal duty and up to 480w on peaks

Behringer EP1500 amp
Stereo mode
2 ohms / channel gives around 1400w .... much more than is needed
8 ohms / channel gives around 560w ..... preferred option
Bridged mode
4 ohm load gives around 1400w. .... much more than is needed

 

IB8 - Eight driver system
Requires 410w normal duty and up to 1050w on peaks

Behringer EP2500 amp
Stereo mode
4 ohms / channel gives around 1500w ( some reports say 1300w) ..... preferred option
Bridged mode
8 ohm load gives around 1500w ( some reports say 1300w)

Possible alternative amplifier
Behringer EP1500 amp
Stereo mode
4 ohms / channel gives around 560w ..... preferred option for this amp, but lacks headroom
Bridged mode
8 ohm load gives around 560w

 

IB12 - Twelve driver system
Requires 670w normal duty and up to 1700w on peaks

Behringer EP2500 amp
Stereo mode
2.7 ohms / channel should give around 1800w ..... preferred option
6 ohms / channel should give around 575w .... not enough power
Bridged mode
5.3 ohm load gives around 2000w

If you're looking for other combinations of drivers, Crutchfield has a great section
