As the very happy new owner of a 450 passion with only 15k miles and ALL the trimmings... I'm a little bit dissapointed by the Becker Navigation and Sound system. Where is the bass??
Has anyone been in the same situation that can reccomended an upgrade that is 'plug and play' (ie DIY)? maybe a bass box under the (heated) passenger seat?
