Chirp upon accelerating

When I start from a stop I get a chirp coming from the back of the car and it's not the tires. Any ideas? Only does it in 1st and 2nd gear.

You sure your just not hearing the supercharger chirp?

Quite common for these cars supercharger clutch pulley to chirp when it engages and is especially noticeable at lower speeds.
