New audio equipment, including a window-rattling Monsoon premium system, is the biggest change for the midsize Grand Am, which returns in two-door coupe and four-door sedan body styles., , The standard sound system for the base SE model is a stereo radio with a cassette player. A CD player replaces the cassette player and adds a seven-band equalizer on the SE1 and GT models. The GT1 goes a step further by offering both cassette and CD players. GT models also get the eight-speaker Monsoon system as standard equipment., , The Grand Am is built from the same design as the Oldsmobile Alero. The two share engines and their front-drive chassis but have different styling and interior features.
