If the headunit is turning all the way off, lights and all. The radio is losing voltage on the Yellow wire. Where do you have the amplifier's power wire connected?

The power wire of your amp, the large wire, where is it connected?

Is the head unit turing off completely or is it just cutting out? Are you powering door speakers off the head unit? ------------- Support the12volt.com

Then it sounds like you have a short somewhere. Disconnect all your speakers and see if the head unit still does the same thing. ------------- Support the12volt.com

Instead of disconnecting the speakers, balance left and listen to it. Then balance right, listen to it again. If it cuts off with only one or the other channel playing, there is probably a problem with the speakers or the wiring of the channel that is making it cut off. If both channels play fine by themself, chances are you have a voltage drop problem on the yellow wire of your radio.

i have an visionik amp that has a built in fan it is popping both of the fuses after it runs for a minute it doesn't pop them as i put them in. i have looked at most of the wiring going to the amp. it recommends two 20 amp fuses should i put like two 30amp fuses and see what happens

What size fuse is on the amp itself?
It might be that 20A fuse may be too small.
