FWIW, I'm a GSM RF Engineer. Two issues with your post:

In the US, phones are limited to 1 W max for 1900 MHz (aka PCS) transmission, and 2 W for 850 MHz.

The interference you hear on your speakers isn't due to the amount of power being transmited, but it's actually caused by the modulation of the signals being transmitted. That modulation occurs at 217 Hz....which is audible.
