Power Acoustic A3000DB mono amp problems

Recently the amplifier began smoking, white smoke but the amp did not cut off, when inspected the capacitors shown below burst. I myself replaced the capacitors all, and it happened again. Want to know what may have caused this and also what other components to check for damage. All i have is a multimeter.

Something same happened to me... I have a PowerAcoustik A3000DB Brand New... and it brokes jejejeje white smoke in the amplifier...jejeje it blow up and burn 12 pieces : 6 voltage regulator seria IRFZ46N (this is easy to find but the next is hard) and 6 audio output serial FB31N200...you want to repair that amp search this pieces

@ dsb100
Driver Board
The following transistors goes as follows...
starting from the 8Pin (JRC4580D)(dip) Ic .. transistors facing away from the ic are;
2/ MPSA42 0r MPSA05,MPSA06
next
2/ MPSA56 or 2N3906 or NTE159
next
2/ MPSA42 0r MPSA05,MPSA06
next
2/MPSA56 or 2N3906 or NTE159
followed by one (1) C1027

at the end of the driver Board where you see (big transistors) starting from the back are
1/ A1023 0r A1013 (BIG)
1/C1027 (BIG)
1/C1027 (BIG)
followed by
3/ MPSA42 in a straight line....

I recommend Changing the (JRC 4580D) 8 Pin IC with the very same one (ORIGINAL) (NO SUBSTITUTES)...

After that is done check the output mosfets (FB31N20D) to see if any of them are shorting,,,
check the resistor at every first pin in parallel with a diode (1N4148)....

Now change Your capacitors with 2200uf 80V...

Broken legs on the rectifiers or an intermittently shorted common mode inductor would be the likely suspects. The common-mode inductor is just to the right of the capacitors in the photo. Install a single 15 amp fuse in ONE of the 4 fuse holders (other 3 fuse holders empty) and power up the amp. Twist the inductor to see if the amp draws excessive current (which would blow the fuse) or to see if it sparks.

Let me know if you have any other questions.

Smoke coming back


The main dc reservoir in the power supply must have burst. This capacitor 47 to 100 MF/400V also releases lot of smoke when it bursts. Most of the times you just have to replace it and the tv works fine.

My amp started to smoke, and cut off,had a real loud burning smell,has not worked since.


Sounds like it was playing? If it was your voltage dropped and the mosfet power supply got toasted. These amps are notorius for burning up at low voltage. Kicker did not put a low voltage shut off on it.,

i think there may be leaky capacitor in your amplifier. there is also chance of ic failure in the amplifier it may be producing noise after getting hot. open cover & carefully see if any capacitors(which are large & round one) are burst. check for excessive heat of the amplifier ICs. replace with same type if u find any of above capacitor or ic defective.

I recently revisited my car after a few weeks out of my hands, and seconds after turning the key and the unit powering up, the sound of popping and shrapnel in the amp was heard and the smell of smoke...


What has probably happened is a short somewhere in the amplifier. Here are some possible scenarios:

1. When the new capacitors were installed, make sure that no solder shorted any pads on the circuit board to anywhere else.

2. There is probably a resistor upstream of the capacitors that has shorted but still appears to be fine. Look at the circuit board & follow the traces that connect to the 2 terminals of each capacitor and follow them to other components. Examine them very carefully. Pull on the wire terminals of upstream & downstream components to ensure they are solid. Check each side of the component with an ohm meter. If a zero resistance is given, or no (open) resistance is given the component could be in question. To properly check it out, one side of the resistor must be pulled up from the board, then check the resistance again. If out of spec, it would need replaced & then it would properly voltage limit the capacitors, keeping them from going up in smoke.

3. This can be a very tricky problem without a schematic. See if you can get your hands on one, it makes circuit tracing much much easier

White smoke is not good. But it may not be what white smoke typically is, which is coolant leaking into combustion chamber... but rather a backfire dislodging exhaust particles.

Get the error codes read and you will be able to know where to go next.

Boss 2500GT mono block car amp white smoke after 5 mins


I'm not familiar with this particular model but this appears to be the filter inductor in a class D amp. If I had to guess, the white smoke is from the filter capacitors connected to this inductor.

You should check with Boss to see if it's available. If it's not, you can re-wind it. You'll need to measure the diameter of the wire to determine its gauge.

If the filter caps vented, you'll have to replace those also.

If the terminals were smoking, it's probably due to loose screws in the terminal block or wire that's too small.

Did the amp work properly after the terminal blocks smoked?
