Hi there.  Can anyone recomend a remote power relay that will turn on with a speaker signal?  I'd like to turn on my subs with a speaker signal from a factory head unit.  Any brand/model out there that will do this?

Thanks.

I believe that PAC makes one that works well, but why not just use either the acc lead from the radio or a power ant/amp turn on lead (if the vehicle has one).

AH!  Thanks for the lead.  The PAC # TR-4 looks like it will do the trick nicely.

I want this because my car, a Lincoln LS, has a feature where the head unit stays on for 10 minutes (or until a door is opened) after the key is turned off.  This timer is inside the factory head unit and is independent of the ACC voltage.  I want the subs to play during this delay.

Thanks again!
