sub-woofer wiring

Just bought this, yes i know ive paid over the odds for it but wanted one so spoilt myself.

Range Rover P38 Sub Woofer Speaker Box | eBay

Is this just the sub speaker or does it have an internal amp?
I've checked out the wiring in my boot and there's a white plug that looks the same as the one on the sub so hopefully it should plug straight in?

The small black box screwed onto the sub casing is the amplifier. Not sure whether it's the older version or the DSP amp.
