ahoz28 Posted February 27, 2011 Author Report Share Posted February 27, 2011 This is the SMD forum, useless without pics., plz show us the blown amp and your electrical upgrades, and how many RF 4 K are you running? These are rough pics from my phone. I will take pics of the amps that broke later when done taking everything apart. Link to comment Share on other sites More sharing options...

ahoz28 Posted February 28, 2011 Author Report Share Posted February 28, 2011 DBR electronics from Texas would not fix my amp. He didn't say why maybe old or bad technology. Link to comment Share on other sites More sharing options...
Chipper Posted February 28, 2011 Report Share Posted February 28, 2011 You can fix it your self if your know the basics of electronics, solder iron, multimeter and so on to fix the amp. The parts that blew where MOSFETs for the power supply and possible some gate resistors and driver transistors <--- needs to work in order for the amp to work. And also check the output transistors. I don't know about this giant amp but just a few basic tips to give ya..... Good luck & sorry for your loss :/ Oh here's a good web site that will help you fix this http://www.diyaudio.com/ go to the left on forums go to car audio and post your prob and they will aide you on checking things.

Guest Posted February 28, 2011 Report Share Posted February 28, 2011 the reason he didnt want to fix your amp is because RF's MEHSA (spelling?) technology is hard as fuck to fix. Link to comment Share on other sites More sharing options...

It must be a pain for what it is. He recommends running smaller amps vs one large amp. They are cheap and easy to fix. Link to comment Share on other sites More sharing options...
Boon Posted February 28, 2011 Report Share Posted February 28, 2011 Don't even bother trying to fix an amp like this. You need a scope, for a start, and a couple of years experience fixing other big amps. Plus these amps use heaps of surface mount (not to mention that god-damned MEHSA) parts so you need to be able to do SM rework as well. I've never seen damage to caps like that. It really, really looks to me like the caps were rubbing really badly on the casing and they wore through and created a short across the power supply section which blew the MOSFETs. Low voltage doesn't blow amps. That's a myth. 10.x volts fo' life! Link to comment Share on other sites More sharing options...
TeamHT Posted February 28, 2011 Report Share Posted February 28, 2011 DBR electronics from Texas would not fix my amp. He didn't say why maybe old or bad technology. Call RF. Tell me...does this smell like chloroform to you? Link to comment Share on other sites More sharing options...
