When I turn it on it shuts off amp


This sounds like a wiring issue. I don't know what you're turning on that it causing the amp to shut off - because you didn't include that info. Double check the installation instructions of both the amp and the other device. Make sure you're connecting to valid points in the car's wiring. If you're still having trouble, please provide the year, make and model car and the make and model of the amp and the other device. Has either worked in the car alone before - or did you install them both at the same time? Are these devices new, or used. Did you see them work correctly before? Thanks!

The amp is gone. if you have checked and double checked and it is hooked up fine. then the amp is toast. Contact the manufacturer to get a replacement if its under warranty.

I have a Panasonic EAA046B amp connected to a Polk Momo speaker system installed on my 2006 Sea Ray boat that was factory installed. Last week when we turned on the stereo all we got was short basey thuds...

Hello, if you know how to use a volt/ohm meter and you are comfortable with taking the bottom cover off the amp I can assist you in testing a few things to narrow down the problem. The easiest way would be to talk to you on the phone if you don't mind. I own a car audio installation and amp repair shop. If you want to do it by e-mail we can do that to. I would have to walk you thru the steps, it would'nt take long. Taking the amp out and taking the cover off takes longer. Anyway let me know. It sounds like you may have a power supply problem. Or, it could be a few other components inside. It's hard to say without doing the test that I would help you with first. Cause the amp is coming on but you say with some thumps coming from sub and nothing from the other speakers. It maybe doing the same on the other speakers but because there are crossovers on them it would cut off that low frequecy noise. You could also maybe have some shorted output transistors but like I said, have to do thaqt initial test first if your up to it. Send me a private message so I can get your info or i'll give you mine to decide what you want to do.

Need help with my Kicker Amp

Some amplifiers don't work well if the signal source has no connection to chassis ground, This could have caused instability in the amplifier and caused it to fail.

It's also possible that the amplifier had a manufacturing defect.

Amp protection

Hi, Off hand, I believe there is nothing wrong with the setup, maybe just not 100% compatible. It's just that the Sony Amp's protection is doing its job (just too good) and the stock radio is likewise doing it's job (but not too good). Just maybe, at poweron, the stock radio sends out a small burst output (maybe capacitor discharge) that we normally hear as a slight thump in the speakers which was when no Sony amp, ok. However, when you have added the amp, you also amplified the thump, which unfortunately the Sony protection reacts to. You can off course let it be since you have figured out a way to make it work or you can try and install a delay on for the power amp or separate it's power on from the stock stereo. The idea is to turn on the stereo with the Sony off and after a second or less, a manual switch or a delay activated switch will turn on the Sony. The idea is to switch on the Sony after the thump has finished. Good luck and hopes this gives you an idea. Pls post back how things turn up. Kind regards.

The Amp stays on because you have a constant 12V to the Remote.
If your stereo remote is no longer working then run a wire from a 12 volt source that turns on and off with your ignition something like your radio fuse in the vehicle fuse box.
As far as the Bass Knob if it is connected properly and still not working check the line for wire kinks or cuts that may have happened during installation if you cant find any problems you can get a universal bass knob that plugs via your RCA cables for under 20 bucks.
Hope this gives u some ideas.
