STA369BWS output configurations

Question asked by shi.winston on Sep 4, 2015
Hi, I'm using STA369BWS as the amplifiers in my application. There are a pair of stereo speakers and a subwoofer speaker. The stereo speakers' resistance is 4 OHM, and the subwoofer one is 8 OHM. I'm using two STA369BWS to drive the stereo speakers in the stereo BTL mode, and the  subwoofer in mono BTL mode. My power supply is 14~18V. The reference configuration in the datasheet for a stereo BTL mode is for a 8 OHM speaker, not 4 OHM. Can someone recommend the output configurations for my application? Thanks.
