1.Decks - Car stereos cannot function without a deck. A deck constitutes any piece of equipment ranging from cassette decks and CD players to MP3s and mini discs. The deck is considered glue that holds car stereo together. The deck controls overall output of sound and allows you to control music being played. All car stereo decks have a minimum 4-channel output for your speakers. If you want more power than what your speakers alone can hold, you may want to consider purchasing an amplifier.

Operating full time, GS300's all-wheel-drive system features a planetary gearset and a wet, multidisc clutch to couple primary drive wheels, at rear, to front.

Every GS has three variations of a new close-ratio six-speed automatic transmission, each designed for optimum performance with their respective GS applications. One of smallest and lightest gearboxes of its type, it includes a sequential manual shift mode, with gear changes made via a lever in center console. An outstanding feature of car is all-wheel-drive system. The more slippery road, more pronounced is its advantage over conventional two-wheel-drive systems.
