My 1200 watt amp has 120 amps of onboard fusing, obviously your 1500W amp should have more.The solution to this problem is to get bigger wire. If you put a bigger fuse in place of your 100 amp fuse, you'll no longer be protecting the wire from catching on fire from drawing too much current, as most 4 gauge is not rated to handle current above 100A.There should be a fuse under the hood, less than three feet from the battery. The fuse should be rated to the maximum ampacity of the wire you are using.</blockquote>
