periph.... the stock amp remote cable reads 9 volts......depending on the amp hes using it may not work with it. I never checked it behind the radio but im pretty sure it reads the same voltage.

He did say it's a 2008 TL Type S... so it must be what godizus said, the noise cancellation system... so he must disconnect the mic from that ACS...
Good Luck

we offer an LVT2 or Low Voltage Trigger. It takes a trigger that is not quite 12V and boosts it up to 12V. Its implemented into our SVENR or is sold separately.
