Do you think that the ford sound system is loud and enough and basey enough? Or do you think its better to have you own system put in?

In my opinion i think the sound system you get in a focus cmax is quality I've been driving my mum and dads 53 plate 1.8 TDCI about and had the music rather loud and it still comes out crystal clear even with the base and reble on max where as with some cars I find the music starts to jutter and sound of poor quality.
