Audiobahn A4601T, only 1 audio channel works

I just received a refurbished unit from the factory. Audiobahn is now out of business so I have no way to return it. I am only getting sound out of 1 audio channel. All of my RCA's work, I can put my old amp in place and every channel works. I tried swapping all the RCA channels and and speaker channels around. Only channel 1 plays any sound. I then bought a second unit, from the same place (refurbished) and it has the exact same problem. I can still put my old amp in and every channel works.

Any ideas?

    Yes, it is the same channel in both amps that produce the output, Channel 1. I tried all options on the switches and pots. I put all the pots in the middle and changed each switch on each channel 1 at a time. I tried different speaker combinations and RCA combinations and only get audio through channel one. I am thinking it is a misswired compenent when inside it got refurbed?? Weird to have the same problem on 2 amps, then to test an amp 6 years old and have all channels work.

Is it the same channel in both amps that produces output?

Have you tried all combinations of setting for the switches and pots on both amps?

    It's possible that someone refurbing them did the same thing (wrong) twice.

    You should disconnect them from the power source and remove the covers to see if you can see anything obvious. If you can't, can you send me a set of good quality photos?

How many watts is the audiobahn a2401t


Hi,

i think it's 100watts on 2 channels,
so further explaining: 50 per channel, but if you bridge them, meaning connecting one wire of the speaker to the plus of one and the pother wire the minus of the other will result in 2 channels converting so to say in one channel and giving a 100 watt x 1 channel.

hope this is useful, and greetings,
Olivier.

I HAVE A A2300HCT AUDIOBAHN I WANT TO CONECTED TO 6 12 INCH CROSSFIRE ALL 6 GIVE ME 1 OHM DO YOU THINK I CUOLD LOWER THE AMP TO 1 OHM IF NOT WHATS MY BEST CHOICE


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.

Amp Problem


my first thought would be the rca's. make sure the rca's are in good condition and also make sure that their in the right spot from the head unit. (some head units have multiple rca outputs or inputs) and be sure that your gains and levels are all set right
