Question about Visonik Car Audio & Video
I'm a bit confused. For Alpine amps, the "M" prefix is for monoblock (aka single channel) amps and the "F" prefix is for multichannel amps. The only M550 I find is an MRD-M550, which is a monoblock, not a 4 channel like you say.
Unfortunately, I can't give you accurate help until we know weather it's truly 1 channel or 4 channel. Then I'll be glad to help!

the fuze could be blown on the amp or the speakers are to much power for the amp at full power so try to turn the amp to half and not to turn the speakers all the way up,.

I do believe this is caused by one of your amp fuses. Depending on which + on the amp is being used. That channel has a blown fuse. have you tried running + and -, + and - to both channels to see if both subs worked? If one sub doesn't then it's a blown fuse or scarred fuse and needs to be changed.

SOURCE: Amp doesn't come on
You did not say whether or not you checked the wiring going to your subs. Many times, a shorted or grounded speaker wire will cause an amp to fail. And if the amp powers up OK with the subs disconnected, I'd suspect one or more of the wires.
Hope this helps.
