addiction2bass Posted April 8, 2009 Report Share Posted April 8, 2009 ive had this mtx amplifier under my bed for quite along time now. i had it hooked up to my 2 10inch RE RE subs in my really old crx i had until it one day poped and didnt come back on. ive taken the amp apart some and it looks like the mosfet or what ever they are called is burned on one and looks like both cracked. i cannt see anything else fried so im hoping its just this one or two parts gone bad and i can simply unsolder them and solder in some new ones. but where can i find these parts to replace mine with? ive tried my hardest to see the numbers and it looks like top numbers H406ad bottom numbers 75339p its not a very big amplifier of course but worked just fine for my little 2 10s, which im currently using as my home theater surround sound bass with a home plate amplifier. figure if i can fix it by just replacing these 2 mosfet chips that would be simple enough and id have a decent little amplifier again and i could even use it for some highs also... cheap fix is always better than a large paperweight!

mrafrica Posted April 8, 2009 Report Share Posted April 8, 2009 i beleive you can find some on mouser.com Quote And far as the best connection ever....... get a huge fucking battery, cut the top off, drop an alt in there and then pour all that into your big amplifier. or just smelt them all together.

Boon Posted April 8, 2009 Report Share Posted April 8, 2009 (edited) Well it's a tiny little amp and small parts so it won't really hurt to just chuck 2 new FETs in there and hope it's ok, but you really need a scope to check the drive signal is ok. Make sure you pull the board right out of the amp and do the soldering properly. Replace those FETs with IRF3205. It's a higher spec part that's compatible http://www.mcmelectronics.com/product/IRF3205 Edited April 8, 2009 by Boon Quote 10.x volts fo' life!

drew028 Posted April 8, 2009 Report Share Posted April 8, 2009 Your gonna need the tools to test it also. Something caused them to burn out. By just replacing them as soon as ur done and you go to try it out.. POOF same problem again Quote Link to comment Share on other sites More sharing options...
emperorjj1 Posted April 8, 2009 Report Share Posted April 8, 2009 aww fis i would have taken it Quote J. JMy CardomainFINISHED COBALT SS/SC DUAL ALTERNATOR PICS theres no such thing as too expensive when it comes to upgrades like that, because imo if you are gonna spend to upgrade then do it correctly rather then be a cheap ass ricer Link to comment Share on other sites More sharing options...
Bumpindemlowzz Posted April 8, 2009 Report Share Posted April 8, 2009 aww fis i would have taken it There was a single red wire that was burnt. I tried resoldering it but it did it again. i should have posted it on here but was pissed and ripped the whole system out and threw it in the dumpster. Just waiting to get better equipment ftw Quote 2010 Silverado 18" DC XL 18 DC 2k XS Power Batts Link to comment Share on other sites More sharing options...
