2000MY R129 SL320 Amplifier location?

[iDrive]

Hi

I will be assisting in the removal of a Parrot kit from a 2000MY SL320, the car has an Audio10 headunit but it is not clear where the amplifier will be located?

On first sight, there are wires cut from when the Parrot was fitted, and it looks like only the F/N/S speaker remains connected to the female speaker connecter that fits in the rear of the headunit?!

I anticipate tracing the wiring from the back of the headunit to the amp, but can't work out where it will be (passenger footwell? under a read seat? in the boot?)

Its a facelift 2000MY, which may determine the location?

Thanks in advance!

If it has one, it is under the back seat.
