If it is burning up resistors you have a power problem. honestly if it does this i would not invest the money into it i woud get another amp by the time it is repaired it will cost almost as much as a new amp. but if you still wanna do it id look threw china manufactures like Alibaba.

Power Acoustic A3000DB mono amp problems

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.

Amp Not working!

If the amp goes into protect mode, it's likely due to shorted output transistors. To eliminate other possible problems, read through the following page:

Amp in Protect Mode - Troubleshooting

If the problems are not with the wiring, follow the link at the bottom of the page to the Amplifier Repair Primer page.

Power acoustik ps2-1600 blowing fuses

Generally, this would indicate that the output transistors are shorted (which is generally a relatively simple repair). But an amplifier that never worked properly could indicate that it has a manufacturing defect. Sometimes, it's as simple as a bridged solder connection. Other times, it could be due to a missing component (which may be more difficult to repair).

The first thing you need to do is to check the output transistors. They will typically be the larger devices clamped to the heatsink. If you find any that are shorted (~0 ohms) between legs 2 and 3, you have at least one shorted transistor.

Before you do anything inside the amp, remove it from the power source and read the following page:

Disconnect all of the speaker wires and signal cables from the amplifier.


If the amp still goes into protect when you power it up, the output transistors are likely shorted.
