how can i do that? I placed the positive on the power and negative on the ground when i was in continuity and nothing happend

 

Remove the fuse and touch the probes of the tester to the metal contacts - polarity doesn't matter. If the fuse is good you should have continuity. No continuity and the fuse is bad. If for some reason you can't get the fuse out you can back probe the connectors to check for continuity. From the sound of it though (foggy/brown appearance) I would say the fuse is bad. Glass barrel fuses are see through when in good condition.

 

All is good!!! Everything works good, had to tune the amp a bit but boy once i did this little type r sounds amazing! Cant believe its only getting 200 watts, sounds like 2 12's :P

 

My amp is not turning on it was showing an red light I try to disconnect power wire n speakers when I'm disconnecting power wire its went off but when I put it back it's not coming back no more red or blue light on my amp I tried to check power from the battery it's there but still I tried to check fuse its looks ok so I'm confused someone help me please
