Blown amp fuse
 

I hooked up a system in my car 2 days ago, and i turned my car on today to discover that my amp wasn't working. so i checked everything and found out that my fuse that is in the amp was blown so i head over to walmart and buy some new fuses.
The first one i put in blows the second i stick it in there. so i undo the power to the amp and put a new fuse in, the second i redo the power it blows. i repeat this a few times and everytime the fuse blows.
What should i do? What's the problem?

I installed my own stuff, but don't know much about electronics so i could be wrong.

But doesn't this ussually mean theirs a short somewhere?

Someone correct me if i'm wrong.

Check and make sure you have a proper ground. Also make sure u putting the right size fuse in there.

that is correct, a DMM would confirm, it would read 0 ohms across the power and ground leads of the amp. Same thing happened to me and I never could figure out why the amp suddenly shorted, it was internal and nothing I could do but tr another amp which worked fine.

Check your connections on either end of the amp power wire too make sure you are not touching the car's body somewhere. If you see nothing wrong, then (small possibility) you could have cut the insulation when installing.

Also, check the wire that gets energized to turn the amp "on" too; not sure if it would do this but you never know.

Make sure the replacement fuse is the correct amp rating, not too far below and absolutely not above the recommended rating.

thanks for the help, I'll look at it tomorrow and tell you what i find

well as it turns out when i ran the power wire through my firewall i somehow but i huge gash in it. pretty obvious problem and an easy fix with lots of duct tape.

Ok, for all the EE's in the house (thats me but i still dont know the answer) why the hell did the amp's fuse blow instead of the inline fuse?

wouldn't it be because the power goes to the amp fuse first?

this is how i see it...

If the wire was touching the firewall, thats basically saying the amp almost totally out of the circuit... the majority of the electron flow is coming from the firewall and moving towards the positive terminal along the power wire, meaning the fuse on the power wire should have blown instead of the amplifier's fuse.
