On mid-2011+ you get that with the Basic Sound (US). It has an upgraded woofer in the premium sound package.

There are a few amps that will fit where the stock amp fits. There wire harnesses that plug into the factory harness from a few sources. I was planning to use the stock wiring to all the speakers. Haven't dug into what speakers will fit yet.

I've stalled on it for the moment as it was more worthwhile putting in a Quaife Diff first (for me).

OK, I think I finally get it, you are saying that we have the same big round grills, but you have smaller speakers behind them (I think I see the outline in your picture), while with premium sound I have a real subwoofer behind the same grills. I thought 09cbb was saying that there were other subwoofers lower on the separation wall.

I might be a little slow, but eventually I get it

Actually, both the 2011+ have a woofer behind the grill. The premium just has a higher quality woofer. The basic before mid-year 2011 had no woofers behind the seat.
