Bumpin the TWP Posted October 9, 2010 Report Share Posted October 9, 2010 one of things i could think of right away was did u have a correct size fuse going to the amp?

audiofanaticz Posted October 9, 2010 Report Share Posted October 9, 2010 It went up in smoke becasue: The amp was ran at too low of an impedance. The amp was ran hot due to clipping or some other reason, and protect circuit didnt catch it, or failed. The amp had a lose power or ground. The amp dipped to low on voltage. The amp was vibrated to death, and with vertical mosfets they break easily and cause a chain reaction. You could of blew a sub, and protect circuit didnt catch it and the woofers voice coil created a dead short on the amp. Looking at the amp it seems like the powersupply went out, killing all the mosfets or most of them, and gate resistors. Repair costs are ruffly $150-$225 from db-r electronics.

techforce Posted October 9, 2010 Report Share Posted October 9, 2010 (edited) low voltage and running too small of fuses for the comps... at least get a battery back there... fuck the bullship burp box rules and try to run your amp with a 20 amp fuse... that fuse popping is a sign of a strain on the entire system, the fuse, cant pass enough power to the amp and the amp suffers... II will run 300 or 200 or none Edited October 9, 2010 by techforce Quote Link to comment Share on other sites More sharing options...
00sdime00 Posted October 9, 2010 Report Share Posted October 9, 2010 You toasted the power supply section... Thermal runaway is a bitch. B is right about the reasons why.

Bumpin the TWP Posted October 9, 2010 Report Share Posted October 9, 2010 300 amp fuse for a 3000 watt amp. seemed right to me A good fuse would be about 200 to 220 amps for that amplifier.
