Just took delivery of my new 92 500 E today.

The car is missing the cd case from the original becker cd in the trunk. Where can I locate one?, or is it just best just to replace the cd changer completely?

The car sounds great, the stereo doesnt, does the stock radio in there have enough power to get better sound by just upgrading the speakers or does the unit itself have to be replaced along with the speakers to get a better sound?

What good speakers fit into the speaker areas without cutting holes in the dash and door panels and rear deck lids to achieve a better overall sound? Not looking to break any sound barriers but I know it can sound alot better than it does now.

TIA
