[QUOTE="Doxquzme, post: 8875053, member: 689267"] One or two, they are still subwoofer outs and are mono summed signals from both left and right. Even the 2 RCA subwoofer pre-outs on the 2nd one are both subwoofer, mono summed signals. Pre-out low level options are also the cleanest signal too. Having 2 is just a bonus should you have dual inputs as most subwoofer amplifiers do. In a single out, I would slipt that at the amp and run a y-splitter to the amplifiers inputs should that be the configuration. While the frequencies are not impacted, leaving one of the dual inputs open on an amp unused/opened also lowers the input signal and the overall volume of the sub amplifier if both inputs are not used. ;) [/QUOTE]
