Help please! Hey what's up guys; I have a problem, when I turn my key to accessory. My sub turns on and makes my car shake without the radio/cd player being on. What is the problem? This started to happen only a couple of days ago. I tried disconnecting the positive but that didn't work. Any other suggestions are welcome. Thanks

Rep Power: 0 Let me guess .... factory HU?
I'm guess that your issue has nothing to do w/ the settings. It has to do w/ the setup.
Basically you don't have an aftermarket radio w/ a remote turn on lead. This wire is on only if the radio is on, and off if the radio is off. Generally you hook up this wire to the remote spade on the amplifier itself.
Since you need a way to turn the amp on and off you hook up the remote wire to the same lead that is triggered by your ignition. The same wire that allows the radio to power up. This way whenever the car is on the radio can come on and the amp will be on too.
The catch is when the ignition is on the radio CAN turn on, but the amp will ALWAYS be on. The amp isn't controlled directly from the radio.
Now you can get into trouble just like you are saying. The issue is when the car is on, so the amp is on. Now you turn off the radio but the amp and car are still on. Since the radio is off it isn't sending the amp any signal. The amp is on but doesn't know what to play. Therefor it just plays garbage.
The fix is to get an aftermarket HU or to never turn the factory radio all the way off.

Rep Power: 0 The Pacific Accessory Corporation, the same people who make the factory steering wheel control modules make a low voltage turn on which works off the speakers. Basically, you would hook it into a speaker wire, and when it senses the speakers playing (The radio being on) it will send the 12+ Volt trigger to the amp to turn on after a 1 second delay. It helps to get rid of amp-turn on noise in factory systems with aftermarket amps.

Also, if your civic has a Power Antenna turn on (Which I believe is most 2k+ Civics) you can tap into that, but I don't know if it cuts out when not using the actual radio on the head unit. I believe it is the Yellow/Green wire on the back of the radio harness. Hope this helps some

Rep Power: 392 hmm... the thing is that on my amp it has a switch where I can choose between stereo and mono. When I flip it to mono, it does this but when in stereo (which I am in currently) it works wonderfully... no unwanted bass sounds. Strange eh?
