a few friends and i were messing with my buddys car and trying different subs and amps in his car to see what one sounds the best. i was hooking up my mmats d300hc in his car and i hooked up the + and - backwards.... well it wasnt good im guessing. his fuse sparked putting it back in, but never blew b/c its a 300A. so i switched the + and -, to the way that its suposed to be (bolth wires are red) and he turned on his cd player and the amp turned on and went to protect and then to green as normal. but it had a buzz noise comming out of the subs. he turned up the volume a lil then back down. but not long enough for me to tell if everything sounded ok.
i could smell a lil bit of burnt stuff smell when i stuck my nose up close to the amp and smelled it. i took off the bottem of the amp and looked around but i could not find any burnt spots. do you guys think i messed up my amp ?
thanks
chris

red wire can be made easily to black by wrapping some electrical tape around it.
I can remember pheonix gold in the old days was protected aginst stuff like this but if you saw a spark and smelled magik smoke then more then likely there is something that went inside of it.

there was a spark on the fuse, nothing on the amp. i had to stick my nose really close to the vent holes to smell a lil hint of it. when i opened the amp, it didnt look like anything was wrong.

It may take a very careful look at the PC board and especially filtering caps in the power supply to find the culprit. Look for burn spots or bloated caps that leaked as the likely component failure. Get out a magnifying glass and search the power supply section of the board very carefully. (Large coils and Caps are the power supply part of the amp) It's likely you blew a filter Cap and they tend to vent electrolyte materials as they fry
Most amps with fuses in them will blow immediately when reversed polarity is noted and save your amp guts. If this amp has no internal fuses, that 300A fuse will not blow unless a major short takes place. The weakest link here, is the power supply section of your amp.
Good luck hunting or find a good repair tech to do this for you.

I don't know that I have ever even seen a 300A fuse in the 15 yrs I have been installing. Are you sure that isn't a typo?

Next time you guys want to play make sure it's nothing you really value. I tell you what Ttocs.... if that's not a typo that amp's capable of putting out umpteen thousand jiggy watts to the 1st power man! Okay maybe not quite but dang....
They've got some but I never seen one used on a amp. He must be talking about the main fuse for the power from the battery

Oh, there out there. we sell 300A ANL fuses out there. we sell them....
ckoscin2 on 08/25/2009 21:25:52
no 300 is not a typo.....its not my car. i ran a 200 under the hood and a fused block in the back w a 100A.
could i send it back to mmats to have it looked at?
swez on 08/25/2009 23:38:12
That might be your best option here. Who know that amp better that Mmats techs. Even if it cost $50.00 for bench fees + parts, it's a great amp to have in your arsenal.
Just contact them first, get an RMA # and let their techs fix it. Yeah, it's not a cheap fix, but this amp is better than most on the market and worth the repair fees. These amps are some of the best out there and much cheaper to fix than buy an inferior replacement.
