Alternate source for 12v power

vermithrax

ok, so I can either:

1. Use the remote amp turn on wire on my aftermarket headunit.

2. tap into the power outlet wire, but this will turn it on whenever the car starts regardless of whether the radio is on. This may also cause damage eventually.

3. Use a relay which is connected to the 12v wire that my HU uses.

4. connect a turbine and wiring harness to a small hamster wheel inhabited by hamsters that only run while music is playing.

Pretty much cover it?

So if I have 2 amps, which I eventually will, plus the steering wheel adapter all connected to the remote amp turn on wire behind my aftermarket head unit (blue and white), this is will work? Not saying it is the right way, but...
