dual channel amp question?

Don't hook them up so that you have one channel 2 Ohm and one channel 4 Ohm unless you like pyrotechnics in your ride. It will fry the amp. Either do 2 channels both at 2 Ohms or Bridged with 4 Ohms or keep the same setup that you have. Read the manual if you have it too that might answer any questions you have about your specific amp.

That amplifier isn't reliable under 4 ohms mono. So the backside reliable ohm load which you would be waiting to twine the subs to is 6. twine the coils in parallel, if truth be told imparting you with 3, 2 ohm woofers. Wiring the audio equipment jointly in sequence promises you a 6 ohm load. in case you have been to twine the coils in sequence and the subs in parallel, you may result with a 2.667 ohm load. yet, greater desirable than possibly, the amp might go directly to guard mode. Or, you may harm the amp. At 6 ohms you will finally end up with approximately 2/3 of the bridged RMS of the amp, cut up between the subs.

each channel can see a different resistance so long as you don't overload each channel. You may find the channel with the lower resistance heats up quicker and more as you are pulling more current through it. good luck.
