Is my amp blown or what?

I turned my stereo on this morning and my subs didnt work. Turns out my power wire fell out of the connection somehow. So I took out my inline fuse next to my battery and hooked it back up and it worked fine. I got out of school and turned it on again and the same thing happened. So i changed connectors quick and made sure everything was tightened and put the fuse back in and turned my truck on and now the power light wont come on the amp. So i switched out the connector one more time just in case and the same thing. I have a volt meter and I thought i remembered how to work it but I dont but im gonna learn again today. What may be the problem? The amp is a concept CA-1302 2channel if that helps.

Double check the fuse to make sure it is still good, sometimes they look like they are good, but they arent.

How does the fuse on the amp itself look?

Doesnt sound like it's blown, they usually smoke when they blow.

Ok so i check the wires from the battery to the amp and im gettin power of 14 on my multimeter. The fuses are all good cause i switched them out. I have good ground. When i plugg in the ground and the positive wire and check them together hooked up i only get .6. Its a new amp and I took all the precautions to unhook everything before i did anything to it. I also check the positive wire with a different ground and got a .5 V.

so you checked the power wires at the amp, and unconnected you got 14V. then when you connected them to the amp you only got 0.6V?

Ok so apparently changing my inline fuse with one that is blown doesnt work either lol. They both looked good so i just assumed that they were. I guess I just learned how looks can be decieving. Now the amp works again with a new fuse. Thanks for the help.
