all of a sudden, im blowing fuses left and right

[Hartman 10+ year member]

My system has been working fine, then all of a sudden I go to start my truck, I hear a pop from the subs, my amp goes into protect for a half second and then the main battery fuse blows. I figured I had a piece of insulation worn away on my power wire or something similar to that. I have 4awg from the battery to a distro block, where two 4awg splits to my component amp and sub amp. I checked the power wire, everything seemed fine. When I disconnected the power wire for my sub amp from the distro block, everything works fine, but the fuse blows as soon as you turn the power on for my sub amp.

After doing some searching, I think the power supply on my amp is fubar. Anything else that would cause this problem?

i had an amp do that it had like bad transistor i think, best thing to do would be to send it to kb audio or return it if its under warranty

Make sure that's the problem first, try it with a different amp. If it still blows, it's probably a short. If not, then it is the amp.

Everything works fine with my other amp connected. ****, how much does it usually run to fix something like this?

I had everything tuned perfectly too. //content.invisioncic.com/y282845/emoticons/furious.gif.fc81ca146dbff91fede3ed290dbc4f4c.gif

Depends on the amp. What amp is it?

Check the wiring to the subs as well. Make sure that nothing has come loose and shorted out.

I will add that everything worked great for about 3 weeks, now it is blowing fuses. Therefore, I know I have the correct size fuse.

check the run of power, ground, and the subs wiring.

All been checked. Still blows fuses even with RCAs and speaker wire disconnected. I pulled the power wire and everything is fine, no cuts. This amp is fubar.

yes it sounds toasted. could have been from a number of things. Low voltage, something metal getting in the amp, liquid in the amp, and others.//content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif

Looks like KBaudio will be getting some money from me since I doubt I'll get anywhere with the eBay seller.
