If you have a two-channel amplifier in your car’s system, you should be able to see 4 terminals; two positives and two negatives. Which it is Philip TDA1554 number. Every amplifier is designed to handle a certain load. Channel 1 will be labeled A for positive and B for negative while channel 2 will be labeled C for positive and D for negative. Switch the state of the amplifier to bridge mode (BTL), and then the speaker wiring is connected across the output stage (positive) of the two channels, and the speaker is not grounded. Bridge mode is a connection method for power amplifiers in the professional audio field. How to: Double your home theater receiver's power. Today's receivers are jam-packed with features, the one thing they lack is power.
