Heeey. I have the Audiobahn A2300HCT and it has a very strange problem. When i start the amp its in the normal blue mode but i have no sound. The one power output (LEFT) indicator shows +3DB (full) the other one shows 0(RIGHT) The fans also doesnt work. I dont know whats the problem. All the wiring seem to be ok. The amp was working fine. Please help me :(

Nope, sell it all on ebay. You shouldn't be behind the wheel anyways.

do you have signal going in? speakers hooked up correctly? speakers good?

Well, sounds like you have an internal damage since it smokes, if it smokes as soon as it kicks on, and blowing the fuse right away, I would have it fixed. But my guess would be something with the ground that is making this happen, or some how your power is grounding on the amp. When ever smoke comes into play, thats never good any way at this point you gotta admitt that thiers internal damage.. blowing fuses can also be cause by over working your amp. along with the sub load at 1 ohm make sure your amp can do the same.. hope this was helpful in some way

Hello VICENTEMULGA,

According to Audiobahn's specifications, the amp is stable at 1ohm, either with the channels driven separately or in bridged mode. With the channels driven separately, the rated output is 1,200 watts at 1 ohm. In bridged mode, the rated output is 2,400 watts.

You'll need an absolute minimum of 2gauge power and ground, and preferably 1/0gauge and a really good alternator to provide enough current for the beast.

Hope this helps.

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.

Basic Amplifier Repair

Let me know if you have any other questions.

check rca, faulty ground does that

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.

This indicates a possibility of a power supply issue, you may have to open up the unit and take voltage measurements to determine if the voltages are correct. In order to do this you will need a schematic diagram of the unit. Once you have the schematic you will be abor to tell which voltages are legitimate. I hope this helps

are there power to the output transistors?

you might not have enough power pushing the amp.... I have two batteries and two caps running
