I am having the trouble with my fuses melting in my amplifier. This takes a week or two of good loud playing before the fuses melt. The amp never shuts down or gets hot to the touch but the fuses eventually melt and than pop. The amp is a digitalis 800 watt T-Class amp. The amp as 3X40amp fuses and my high amp has 2X30 amp fuses. I have a 5 farad cap and a 120 amp circuit breaker under the hood. Could the circuit breaker be limiting the power to the amp and causing the fuses to be getting hot due to lack of current from the battery almost like creating a short circuit? All of the power cables are 4 gauge.
No, nothing can "limit your current flow" and cause fuses to overheat like that, unless you have a high-resistance connection AT the fuse holder.
Sounds like you may have an amplifier problem, or an amplifier cooling problem. Take it in for bench testing and repair if necessary. That amp was made by Ultimate, I believe. I also believe they are now out of business you may be SOL for warranty work...

Support the12volt.comDoes your amp have a good ground? Try measuring the resistance from the amp's ground point with a digital multi meter.
Checked the ground and it is good. Grounded directly to the cab of the truck.
fuseblower now equals fusemelter? I am going to guess you got an internal problem with that amp but I need you to explain something to me. You gave the ratings of the fuses in both the T class and the amp you are using for highs. Did you just do that to provide information about the current draw concern or are the fuses melting in both amps?

Raven, I gave the fuse ratings of both amps just to make sure that I had provided enough information. The amp on the highs is fine, no issues at all. I will be trying to find somewhere to get the amp checked out over the weekend.
