Turns out the Infinity is capable of very good bass and the trunk of a Mercedes 126 seems to be far less air tight than a 123. I drove a lot this weekend and did a lot of tweaking to the point where I was able to achieve too much bass. I know some people believe there is no such thing as "too much", but I am simple after good clean bass which makes up for the rather smallish speakers that one can fit in the rear deck without major modifications.

Adjustments to the head unit are one of the keys. It helps to have a newer style head unit that understands subs and has adjustments to compensate for them.
