Why is my fuse blowing all the sudden?

Hey everyone.I have a modest stereo set-up in my car and I am suddenly having problems with a fuse blowing. I have an Alpine head unit, Kenwood amp, and a single 10 Alpine sub. I have had this set up in this car for about a year and a half, and had the same set up in another car for three years before that and never had any problems. Now for the past week, the fuse in the wire running from my battery to my amp keeps blowing. When I replace it, it is good for about 30 seconds, and then it blows. Any advice on where to start troubleshooting?


most likley when the bass hits its hardest or deepest its to much for your amp so it blows your fuse try turning your bass booster down or the bass alltogether.
Start by disconnecting the wire from the amp. Replace the fuse and see if it blows. If it does, there is a short in that wire. Look for somewhere where the wire has rubbed against metal, like where it goes through or around the firewall! If that is not the problem, re-attach the amp power with the amp off! See if the fuse blows! If it doesn't, turn on the amp. What you want to do is continue testing components until you find the problem!
