[QUOTE="n2audio, post: 8607228, member: 540940"] Yes, you can. having different impedances on different channels of a multi-channel amp is never a problem as long as none of them are below their specified minimum. But don't get caught up with power ratings on an amp like that. Judging by the 40A of fuse protection it is drastically over-rated. Figure on 100x4 at 2 ohms. Probably ~75x4 at 4 ohms. So if you have a pair of 4 ohm speakers on 2 channels and a pair of dvc 4's on the other two you'd be looking at about 75w per speaker and about 100 per sub. Don't run the subs at 2 ohms per channel. Wire them for 4 and bridge those two channels. [URL="https://www.the12volt.com/12voltimages/2_4ohm_dvc_4ohm.gif"]https://www.the12volt.com/12voltimages/2_4ohm_dvc_4ohm.gif[/URL] [/QUOTE]
