First off, Optima actually recommends the Yellow Top for heavy Audio solutions...

Unfortunately, they do not list a battery for the Crossfire, or for that matter, an Mercedes later than 1971.
Do some work and you might find a cross-reference to an Optima by working back from the MoPar battery number, then find a car that uses that battery that the Optima site DOES list, and bingo...
