amp fuse keeps blowing
So I have two amps installed in my car. One under the passenger seat and one in the trunk. They have been working great until today. I installed a new box in the trunk and noticed the amp was not powered up. I checked the fuse and it was blown. The amp under the passenger seat is still fine. I bought some fuses and have blown 5 after trying to figure out the issue.
Any ideas why it is doing this all of a sudden?
Thanks

Well it is strange because the amp was fine before, same sub. I took the sub out, made a new box, hooked it up and noticed amp was dead.
I just thought about something I may have done that was stupid. While the sub was out I left the speaker wires exposed. Could they cause a problem if they were to touch or even contact metal. They may have done both at cetain times .

If you've shorted the wires or they touched ground, that could kill an amp.
Usually it just blows a fuse and that protects the amp from damage. If you have oversized fuses, the amp will die before the fuse goes.
Most high end amps have built in protection, so you can't hurt them.
I'd suggest opening up the amp, usually if its taken a big enough hit to blow fuses again and again, you'll see and smell the damaged components or burnt traces.
The little black boxes come with smoke inside and the trick is to Not let the smoke out....
