make sure there is correct wattage with the subwoofers and the power supply

This means your amp is getting to hot and going into protection mode. One cause of this could be how you have the speakers wired to the amp.

Yes the amplifier will become very warm or "hot". It is a good idea to place it in an area that will recieve plenty of ventilation and air flow. Some companies sell cooling fans for larger amps.

i got the same amp they good amps but low watts , at one point in time ur speaker wires touched an fried a fuse in the amp . u got to take it apart an see if u see burn in the bord around the fuses an around the speaker out put hopw this help please vote if it did

Send us the model, please.

First of all please check if the speakers are connected in phase. That is if all the positive and negative terminals are connected OK. Simple way to check is to turn the fader control first to the rear and then while playing some music with heavy beat ( dance music ) turn the balance to one side. Listen and see if you are getting good bass. Then turn the balance and bring it to the middle ( 0 ), when you do that if the bass is becoming flat-- one of your back speakers are out of phase and canceling bass. If thery are in phase the bass should become full and rich. Do the same by turning the fader to the front and try swinging the balance. If all is Ok , yes you will need an Amplifier to satisfy you. Make sure you buy something that can match the power of the speakers you have installed in the car.
The out of phase syndrome is a very common problem.

Hi,
May I know you're email add, I will send to you the copy of the service manual. It has a picture of pin-out of your unit...

The head unit will keep a record of the stations you preset, not the amplifier. The problem is with your head unit.

i have the same amp 600watts. what u mean repeat is it pulsing or whats it doing

Sure is.

The sony is bridgable as follows:

100W x 4 @ 4 Ohm

100W x 2 + 250W x 1 @ at 4 Ohm

This will allow 2 channels to run 100 watts each @ 4ohms with an additional single channel with 250 watts @ 4 ohms.

The single sub channel is created by bridging channels 3 & 4

If water did get into the cover of it the circuit board may have got condensation inside and on it. There is no way to tell if there is condensation is to look inside the amp and inspect the circuit board. Also I would not run power through it because if there is condensation on the circuit board you will fry the components.

you may have already blown the amp...if it is doing this with no speakers hooked up to it trace your power and negative line to ensure there are no breaks or kinks in the line...also verify you ohm loads and such and that the amplifier can handle what you are introducing to it( if in fact there are speakers hooked up to it)..as i said b4 however there is a good chance the amp is blown already

My best guess is that your over loading the amp. Check and see if the amp is hot when it cuts off. Most amps have a "safety" cutoff that will shut it off if it get to hot

check your ohm load on the sub and see if your amp can do the same, That is why every time it shuts off into protection mode. Check your gain level on the amp to this is not a volume knob for your amp, It is to get both the amp and cd player on the same page. Hope this was helpfull
