Aerial Adaptor for aftermarket HU?

[miscking]

Hi,

I'm about to purchase an aftermarket HU, but I've been told I need an adaptor for the aerial.

This is the one I have been told to get:

The question I have is thatsince my car has two antennas (the two cables in the picture below on the right - the yellow one and the black one), will this adaptor accommodate both those connections into the new HU?

Also, I have been told by one audio installer that from the connections, the car is half amped. However, another one tells me this is fully amped?

How can I know for sure?

I have a spare aerial adaptor if you want? Also if you want ignition controlled connection like the oem stereo you need a proper wiring harness. When I changed my concert to double din JVC I got the following harness http://www.ebay.co.uk/itm/400579829561
