Hello, im having problems with my Audiobahn a2300hct amp. Ive bought it from ebay, putted in my car, added my sub wirred on 2 ohm. It had pumped it for about 5 mins, and then went into a protection mode. Cant start it back. Any ideas whats wrong? Also after that, (as i cant be in car without music), ive putted my old amp, and i had a surprise, that i didnt liked, my old amp is not working aswell. Any ideas? All wires and fuses are fine.

HELLO THESE AMPS ARE FAMOUS FOR DRAWING ALOT OF CURRENT AND IF YOU PLAY THE AMP WHILE THE VOLTAGE DROPS FOR TOO LONG YOU CAN FRY THE AMP BUT AS FAR AS THE SECOND AMP NOT WORKING AS WELL YOU MAY HAVE A PROBLEM WITH THE RCA'S OR THE OUTPUT ON YOUR HEAD UNIT WENT BAD OR YOU HAVE A BAD GROUND CHECK ALL FUSES THEN CHECK THE GROUND WIRE TO MAKE SURE ALL PAINT HAS BEEN SCRATCHED OFF AND THAT IT IS CONTACTING BARE METAL THE ONLY OTHER OPTION IS FIND A FRIEND THAT HAS THEIR WIRES RAN AND HOOK UP YOUR AMP ON THEIR SUB IF IT WORKS THEN TRY IT WITH YOUR SUB IF IT GOES INTO PROTECT THEN YOU MAY HAVE A BLOWN SUB CAUSING THE SHORT HOPE THIS HELPS THERE ARE ALOT OF OPTIONS START WITH THE WITH GROUND AND GO FROM THERE

SOURCE: amp heats up and goes into protect mode

Hi Saint108. You're describing it well, and i know what the problem is already. The MA audio amp, can't hold with a 2 ohm load. It's too low for that amp, that's for sure. Those are budget amps and they are not well built enough to handle low ohm setups like that. It's overheating and there's no ways around it.. Other than wiring your subs differently ! Just wire your sub directly (not in parallel) in a 4 ohm load, you will notice it will stop overheating that much. Do it quick, you'll most likely fry your amp giving it such hard work !! The HUM you're hearing could be related to it also. Try that, and keep me posted on the status. Thanks ! Cheebster.

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

SOURCE: low ohm light wont go off

pbabin is correct, that would cause resistance to be at or near 0 ohms and the amp would pull a lot of current (if it did not go into protection mode).

SOURCE: best way to set up my car sound system???

This is a multi-tiered question. First of all, you're going to want to run the subs at a 2ohm load (if the amp is capable) to get the maximum power from it. Use the 5.0.1 for the subs only, that's what it's designed for. Run the cap in conjunction with only the sub amp as it has the largest power requirement. You can not link the two amps to increase output as they are first of all different amps and second of all not designed to run that way. Some amps are but they must be identical.
Set the crossover on the sub amp probably no higher than 80Hz (I like it lower than that but that's a personal preference) and turn the sub-sonic filter off.
Now, one of the most important things about a subwoofer is it's encosure. If it's a properly built box designed for your subs specifically then you should be ok. You dont' specify if it's ported or sealed etc. That would be helpful to know as well as it's approximate size (air volume).
The head unit can also have some bearing on how things sound, as I recall the Sony X-Plod units are fairly decent for the price and if set up properly should sound ok.

If you need further assistance please provide a little more info about the sub enclosure etc.

good luck!

SOURCE: audiobahn a8002t amplifier in protection mode

Let's measure some voltages. If you have a DMM measure the DC voltage at your amps power supply input. If much less than 10 volts I would suspect you may have possibly damage your power wire. When you have a lot of current flowing through a wire the resistance will change and cause a larger voltage to drop across that wire. Having to low of an input voltage is a trigger mode for some amplifiers to go into protection. Let me know what you find and we can go from there.

Can i get down to a hafe of ohm witj the a2300hct


Yes and No.... You can wire your subs down to a half ohm and run it on your audiobahn amp however I would not do that if I were you the amp is only 1 ohm stable and these amps are famous for running hot at 1 ohm and go into thermal shut down I have owned quite a few and they all have this problem but running your amp under that ohm load will eventually cause the amp to fail it's not an if but a matter of when hope this helps

Hi, if you wire all voice coils in parallel, you will get down to 1.5 ohms. That is the lowest you can go with these 2 subs. Just hook the amps' positive to all 4 positive speaker terminals and the amp negative to all 4 speaker negative terminals. Please let me know if you have more questions, and thanks for using FixYa.

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

    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.

    Wierd stopped working audiobahn a2300hct


    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.

    Amp. Audiobahn a2300hcx


    If the subs are dual 4 ohm voice coils and if your amp is good down to 1 ohm, your best bet is:
    1. Connect the voice coils in parallel ("+"s together, "-"s together). This will make the impedance of each sub 2 ohms.
    2. Connect the subs in parallel.
    3. Bridge the amp to one channel.
    This should max the amp out at 2400W, which means about 1200W per sub.

    If your subs are single 4 ohm voice coils, do the same steps, but you'll only be able to load the amp to 2 ohms, which means about 600W per sub.

    Also keep in mind that box size, type, and quality make a big difference in how subs sound.
