[QUOTE="Prowler573, post: 966212, member: 561023"] 175w/channel X 2 channels @ 4 Ohm stereo means that the amp will produce 175 per channel across two channels when presented with a 4 Ohm load. When you lower the resistance being shown to the amplifier to 2 Ohms rather than 4 Ohms when configured in stereo (2ch in this case) it will increase its output to 350w per channel across two channels. When you bridge the amplifier to a single, mono channel (connect the positive output from one channel to whatever you're driving with it and the negative output from the other channel and select the mono mode if applicable to that specific amp) then the power output will increase to 700w but only on a single output. What resistance load you will/can show the amplifier will be entirely dependent on the voice coil configuration of the sub(s) you choose to use.
