Hello, question.
Land Rover LR2 2010-2012, I want to install the original subwoofer
Is it enough to replace only the amplifier and install the original subwoofer, or will I need to do something more?

It depends on what you have, and what you are hoping to achieve. The standard Freelander subwoofer isn't any better that a good universal under seat sub available from several audio system manufacturers.
The Freelander sub isn't a patch on the wife's Audi A5 B & O system sub.

I only keep mine because I don't like messing with the car factory set up, but if mine was missing the sub, I'd use something more modern and more universal. 2009 Rimini Red SE TD4. Soon to be sold.
Hyundai Ioniq 5 Ultimate on order.
Gone. 2006 Tonga Green i6 HSE.
