[QUOTE="Saint211, post: 6833039, member: 564903"] Well, its not as if there is a switch you throw to put it "in 2 ohm mode." This is determined by the impedance of the speaker and how they are wired. I can almost guarantee being alpine those are 4 ohm speakers. I also know that amp is 50x4 @ 4 ohms and 75x4@2 ohms. If you wire one speaker off of each channel each speaker will be getting 50 watts RMS. This is your best option. If you take the two speakers and parallel them to 2 ohms and then bridge them it will be the same as a 1 ohm stereo load which will heat that amp up and probably blow it in time. IF you series the speakers to 8 ohms and bridge them, you will get 100 watts rms at a 4 ohm stereo load, but lose fade and balance and complicate wiring more. One speaker per channel at 4 ohms really is your best option unless you get new speakers or get a new amp. [/QUOTE]
