welcome brother..... I can say that you are going to want to upgrade to speakers from the line of Harmon Kardon, or MB Quartz, as they are known for BMW's and aftermarket replacements as well as the fitment of the speakers are almost perfect.... as for acceleration, I would definitely take the car to a BMW dealership if you do NOT have a mechanical side to you with cars, as they do get complicated. Otherwise I would do a complete tune-up on the car, including new spark plugs, wires, distributor cap as that was a problem for these early model E36'rs, change the oil, filter, air filter.... along the lines your car might throw out a CEL or you might correct this with just the tune up.. whatever you do, good luck and hope you enjoy the forum...
