Most of the time when a high power amplifier starts making noise not all the time but every once in a while or even all the time its the ground, if the amp turns on its not the power cable. try moving your ground to a different location or try using double grounds. the better the ground the better the sound. and as for turn on pops, put a toggle switch inline on your rem wire and turn it on after the car is started.

Check all the wiring. It could be a loose connection since it's intermitent. Really pay attention to the power cable, both the end for the amp and the one that's going to the battery cable.

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.

If the speakers are still fine, then I'd say it blew the transistors in the amp.

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.

Fix subwoofer


Pop open the back side of the sub and see if the to connections are soldered firmly to the wires/drivers themselves & make sure your system is grounded meaning the 3 pronged plug has to have the 3 post still connected to the power cord. If its broken off as most people do it'll cause that feedback or dull hummmmm noise.

My audiobahn eternal is making a rattling sound when it plays certain notes


might be your wires inside the box. My brothers does the same thing on deep notes, took the sub out and shorten the wires and seem to stop that noise or kinda rattling sound. I had two 12's the same ones you got, the noise i had was my 12's blowing the box apart lol. Don't hurt to check your box every now and again. hope this was helpful

I have 2 AW1206T's how do you know when their blown?


when a sub is blown it usually makes a scratcy or grinding noise if you push the sub in but if its blow it realy wont make much of a sound so it sounds like your voice coil is going out you will want to get this looked at quick or it can get expensive...i had one were it was cheaper to buy a new sub rather than fix it. it can also just be it disorting from too much power. i would never go over the power limit when dealing with 3000 watts, that can get realy expensive quick
