Probably not. At 12V, 150 W (max power draw for the Opus), you are pulling 12.5 amps. Add in the power from the stereo, and you probably pulling about 20-25 amps, and most likely, the fuse is rated at 15 amps. You can check your fusebox on your car, though, and see what that particular fuse is rated at.
Of course, you could always replace it with a fuse rated for higher current, but I wouldn't recommend that since there is a reason that rating of fuse was used for that circuit. Too much higher and the wire might not handle it.
