Schematic in PDF format for a bridged-tied-load subwoofer amplifier labelled 2050, where BTL means two amplifier halves drive the speaker in bridge mode for higher output. The name does not say whether 2050 refers to a TDA2050 chip, so check the drawing itself. Use it to follow the low-pass filter, bridge wiring and power supply when building or fixing a sub amp. The (2) suffix hints at a duplicate, so compare it with any other copy you have.
