How to wire to achieve 2 ohms
When the manual for the amplifier states the following:
Audio section
Rated power output (+B = 14.4V)
Stereo (4 Ω) + SUB
................................ 60 W × 4 (20 Hz – 20 kHz, ≤ 1.0 % THD) +
400 W (20 Hz - 200 Hz, 1.0 % THD)
Stereo (2 Ω) + SUB ................. 75 W × 4 (1 kHz, ≤ 1.0 % THD) +
600 W (100 Hz, 1.0 % THD)
Speaker impedance ............................... 4 Ω (2 Ω to 8 Ω allowable)
(Bridged connection: 4 Ω to 8 Ω allowable)
Frequency response (+0, –1 dB)............................ 20 Hz – 20 kHz
Input sensitivity (RCA)............................................. .............. 0.2 V – 5.0 V
Signal to noise ratio............................................. .............................. 100 dB
Input impedance .................................................. .................................10 kΩ
Low pass filter frequency (-24 dB/oct.) (SUB)
.................................................. ...................50 Hz – 200 Hz (variable)
High pass filter frequency (-12 dB/oct.) (A.ch/B.ch)
.................................................. ...................50 Hz – 200 Hz (variable)
Bass Boost Control (40 Hz) (SUB)................ 0 – +18 dB (variable)
How do I wire this up to achieve the 2 ohms numbers with 4 4ohm speakers?

Re: How to wire to achieve 2 ohms
Looks like there's 4 channels. If you try to wire 4x 4ohm speakers to 2ohm you would have to wire 2 speakers together. Which means you'd only be able to use 2 channels of the 4. On top of that it'll be sharing the wattage of 1 channel over 2 speakers.
