Question about AudioBahn A2300HCT Car Audio Amplifier

1 Answer

I have an audiobahn a2300hct with blown components.

The amplifier has 2 blown transistors and 2 blown resistors. The part numbers are IRFZ48V IR 309H 42 85 for the transistors and 2 220 ohm resistors. I can't find out where to buy them at. I called some part stores where I live and they said I have to order them from the manufacturer. Does anybody know where I can get them.

^ from Digikey.com are a good replacement. You need to replace all of the Z48s on the side of the amp where the ones that failed were located. Digikey will also have the resistors. There may be other problems. If you're new to repair work, read through the following page.

I'm working on an audiobahn A2300HCT and it seems to have a dead short in the front end of the power supply (The fets,caps and rectifiers will all have to be pulled, one at a time.Any suggestions?


Hello rick27,

I'm assuming that you have already pulled the board out and cannot visually locate any out of place looking component and that you've inspected the board for solder bridges, broken pieces of wire, and other signs of FOD.

If this is the board you are looking to troubleshoot, I'd start nearest the fuses and work systematically from there. You can test many components if you just remove one lead from the circuit. Both diodes and capacitors can be field-checked quickly with one lead disconnected.

Reversed 12 volt and ground wire when i installed it...now the red light is on AudioBahn A2300HCT


check for a short or burnt trace by the negative (ground traces) on the power side of the board

HEY I HAVE 4 GAUGE GROUND & POWER THAS WHAT THE AMP ALLOWS. I TRY 0 GAUGE BUT IT IS TO BIG FOR THE AMP. A2300HCT.


Hello again VICENTEMULGA,

Audiobahn's website has apparently been shut down and it's my understanding that they are no longer manufacturing any new products. And not supporting the old ones, online anyway.

But I did find this site that sold the A2300HCT and still have the specifications listed. The 3rd from the bottom in the description shows "1/0- or 2-gauge power and ground leads recommended".

At the very least, you should consider running 1/0 or 2-gauge from the battery to a distribution block and then run a very short jumper from the distribution block to the amp.

AudioBahn A2300HCT no sound


Generally, if the amplifier smokes, the power supply FETs have failed.

Many times, the output transistors fail and that causes the power supply FETs to fail.

Audiobahn won't release schematics. The amplifiers are relatively simple and a schematic isn't generally required.

If you know how to check the transistors, check them to determine the severity of the damage. If you don't know how to check them, read through the following page following all links provided.

You buy replacements, you don't repair them. What are the numbers on the transistor?

Disconnect all speaker wires from the speaker terminals of the amp and disconnect signal cables from the amp. If it powers up normally, the wiring and speakers need to be checked. If it still shuts down, the amp likely has blown output transistors.

It's likely that the output transistors have failed. If you measure the resistance between the second and third legs of the large transistors adjacent to the large (green?) resistors, you'll find several that read ~0 ohms. Its likely that only one of several that read 0 ohms is defective but all that read 0 ohms in the board are operating in parallel and must be replaced together so they match (electrically).

Disconnect the amp from the power source BEFORE trying to measure the resistance across the resistors.
