2- 10" Woofers w/ 1,000 watts, not bad for a factory system. Funny thing, he bought the car for a daily, then buys a new civic, mustang stays in the garage with the Boss 351. It's a nice car, I actually like the way it drives and rides. Since he drives like an old grandma, not too sure on the power, but it should keep up with a stock LS1. He's toying around with keeping it and doing a blower, or getting rid of it and buying the GT500 Convertable.
