I just installed a new alpine cd player in my 82 300D, with some infiniy kappa rear speakers. (the orginal size.) the problem is, the rear speakers have no bass to them, although the treble works well. When I bought the car I was told that the rear speakers never had a lot of kick to them no matter what kind of speakers/tape decks that were put in. Is just a defect in how benz built their speaker housings or is there another problem at hand.

Sounds to me like you may have them out of phase. Try changing the terminals around on one of the speakers. The bass in Benz boots is great so shouln't be any probs!!

if they are 4 inch speakers youll never get good bass. I replaced my shot 17 year old original MBs with Rocford fosgate 4"s in my 280ce and they are marginal at best. The front is a little better due to the reflex action of the dash. -Josh

The issue is generally speaker size. If they are out of phase, correcting that will certainly improve the bass - but don't expect thumping or even halfway accurate, tight bass. Fact is that you need at least 6.5 inch speakers - I have had them installed with a bit of struggle. Bass tubes or other subwoofers won't help much unless you can live with them in the cabin, and that's not easy!
