Power and led on but yet no sound

My amp turns on and the led turns on as well as the fan when it is grounded. but on the side where you connect the rca cables there is 2 more leds. one says power and it is green and the other is red. the red one is the one lit. there is no sound coming out of the system. the battery is supplying about 13.8 constant volts and im running with 4 guage power and ground. any help is appreciated.

    took out the box the subs are correct. the connection from the sub to the amp is correct. i disconnected the power completely and removed all fuses for about 2 hrs. connected everything together and still went into protect. it doesnt even start on green led power. it starts automatically on protect.

    disconnected every wire and he fuse. plugged in the power ground and remote wire. put in fuse. turned on car and saw the power led light up but then faded out and the prot led lit up instead. the speaker cables and the rca were disconnected. what can it be is the amp fried, but why would it go into power mode if its fried?

    lets try something again,disconnect power cables,short between terminals G&P G&R (amp)may see a little spark but ok then try reconnecting again but without rca or speakers.If amp still goes in prot you may have some blown fets or output semiconductors.

So it is receiving power but not turning off? Sounds like the sense cable is not connected correctly. Amps have a sense cable that determine whether or not the head unit is powered on. They use this sense to power on or power off. If the sense cable is connected correctly and is getting the correct voltage, then the relay may be broken.

Your friend has damaged his amp. The power light coming on means that the amp's power indicator LED is at least working. That light is only there to tell you that the amp is receiving power on it's 12 volt rails, not that it's necessarily using the power in any way other than warming up the amp's internal circuitry. When you say the amp gets power, I'm not clear on whether you mean the amp works in that fashion, or there's just a red LED glowing but nothing else happens. The amp needs to be repaired, and I would suggest to him to not apply power to it again until it is checked by a professional. The power supply has probably been damaged, and it's possible, depending on how the amp was mounted, that it was searching for ground through the amp's chassis if it was screwed into metal at its mounting location. All that seems certain as of now is that the LED works, but nothing else, unfortunately.

Is the brutus amp blue led light suppose to stay on when the car is off?

No. The LED should be off when the radio is off (amp turns off as well)

It sounds like you have constant 12volts applied to your remote turn on lead. The amplifier will have 3 connections for power:

1. 12volt constant
2. chassis ground
3. 12volt switched power - this wire should come directly from your head unit. It only sends 12 volts when the radio is on allowing to amp to power up only when the radio is on.

No sound

What brand of reciever are you using. Most pioneers have a floating signal ground and the shield of the input at the amp needs to be connected to chassi ground. Also if you had a previous amp failure and the power ground in your old amp opened the current to power the amp will flow through the signal ground of the reciever and burn the copper trace on the circuit board in the reciever. test this by connecting signal cable shield to car reciever chassi.

My amp has power the led is on but no sound

See what happens if you apply a temporary ground connection to the RCA input jacks ground connection while it is running. You might want to turn the volume down before you do this just in case it works.
