It is possible that the amplifier had encountered a fault with a higher current drain which had triggered it to a protection fault condition. The fault can be your output drivers- the MOSFETS/IC's fitted for both the channels, Use a meter after disconnecting to check for short in the drivers.Now that you have found the damaged components you can change them.
These items can be pruchased from any electronic spares parts shop.
After the job is done before you power please check the following:
Disconnect the positive and negative voltages to the output and see if the protect changes. Even a fault in the preamp stages that drives in high current into the output can shut the Amplifier. Sometimes this can be a noise like a HUM or HISS before the protect works. Faulty capacitors in these circuits also can cause similar issues and needs close observation.
You need to confirm and replace the specific stages or outputs. If not there can be issues in the mother board, maybe the protect circuit by itself is shutting off due to a faulty bias , maybe a leak in any voltage/current sensing circuit. Also disconnect the speakers and test, if the protect is off then check for short on the speakers.

visonik v218xt 300W X 2 channels right cannel causes protection light to go out and thumps.
I have the same exact problem, mine's a QSC plx3002
XTANT A6001 amp. any info on channel block system circuit pin checks,and measurement specs,and or schematics sys diagram. your help is greatly appreciated. thanks
i have every thing hooked up and i cant get power to the chanel i have a 1 chanel d class 3500watt boss amplifier
i can't find a diagram to see wich resistors use this amp on mosfet transistor grrr
To all, There is no place where you can download a schematic for this amp, if your lucky someone on here might have one and help you otherwise you have to buy the service manual which is between $10-$20. Also basicly to everyone you need to buy the service manual or someone on here has them and will help if your lucky. pbabin will help you out a lot, ?he has a site you should check out also dedicated to repairing car amps. www.bcae1.com He also has a lot of service manuals so he should be able to help you all out as I can to, I just don't have schematics fot those amps. Clarifying your problems better and giving model numbers helps greatly. thanks
