Remote Turn on for sub amp

[Panoz]

Hello,

I would like to install an amp (JL Audio 250/1) in my 08.5 MS3. If possible, I'd like to avoid taking the dash apart (in my experience, trim pieces never go back perfectly and always end up rattling).

So my question is, where else can I find an easy place to tap into for the remote turn on?

Thanks,

-Paul

the power circuit from the cigarette lighter, or anything else that is only on when the car is on.

ALSO, the Mazda 3 dash comes appart and goes back together quite well actually...
