I've got a 2006 Scion tc with the factory amplified head unit (ipod, subwoofer, etc) - the RS2 package.

The Parrot support folks tell me there's a wiring kit that makes it a plug-and-play install - but I wonder if the Parrot should really be plugged in before the amplifier or patched into the speaker wires after the subwoofer.

Has anyone done it? What's the best method - just use their wiring loom (http://parrotkits.com/donotcut.html#QCTOY-1) or DIY-it after the amp?

Thanks!!!
