If your amp can drive a 4 ohm load in bridge mode, then each channel should be drive a 2 ohm load successfully. To get the best out of the single driver wire the voice coils in parallel connect to one channel and leave the other channel for another job, time to add an extra woofer;)


ONE channel of the amp used here




or some other configurations that would also work. voice coils in series, not as efficient utilisation of power available however




or using both channels of the amp driven from the same signal source. both channels driven but amp only delivering half the power it is capable of




I would go for the independent setup with just the one driver, or the parallel setup with adding an additional woofer.

@plaz.....I said "To get the best out of the single driver wire the voice coils in parallel connect to ONE channel and leave the other channel for another job" .... appears that you have misinterpreted the answer i have given. Wiring multiple drivers parallel and also series can produce odd damping factors for amps to control effectively. I would not use bridge mode with 2 drivers wired for 2 ohms then in series, I would use 2 drivers wired for 2 ohms, and one on each channel. Same power output is achieved, without the complex "harder to drive" load presented to the amp operating in bridge mode.

I have the same problem, after I sold one of my Solobarics, the amp can only operate at 4 Ohm in birdge mode, my solution, I hook up the amp in bridge mode to only 1 of my sub's coils, the primary (white dots) and the result, amazing sound, maybe I'll let that configuration or maybe I'll buy a new amp capable of 2 Ohm bridged mode, Regards from Mexico!!
