I'm installing an amp and subs in my trunk this week, and I want a way to turn them off if possible.
Would putting a toggle switch on the remote turn-on wire work for turning it on/off without hurting anything? By the way does anyone know if the remote-turn on wire from head units send power constantly, or just when the radio is turned on/off ?
Just when the radio is turned on.....that should work just fine...

If we learn from each success and
each failure, then we can improve ourselves
yes your remote will only turn the amp on off with the radio. you also can connect it through your ignition with a toggle switch or with the ignition itself, but having the remote I would go that route.

You know you have the right amount of pressure when your eyes start to water! Now you've got Juice!
If you hook up a switch to interupt the amp's remote turn on, you should only turn the switch to the off position when the radio is off. If you don't do this, the speakers running off that amp will give a huge pop. It's not good for them. The reason for this is that there is still an audio signal running to the amp when the power is turned off. Normally, radios and other audio gear mute the audio signal before cutting the power. You will also likely get a trun on pop too. Shop around for a preamp fader. They used to make some preamp faders that would allow you to have a gain/volume control only on the sub amp's audio signal. This would allow you to adjust the volume or shut off the audio if wanted to. They now offer the same feature in most decks with sub-out on them.
