The worse the amplifier design and implementation the more the load impedance current delivery deteriorates.Īt best expect ~3times the single channel when bridged into the same load resistance/impedance. You will not get 5.2W into 4r0 from an amp that gives 2.6V into 8r0. If you decrease the load resistance/impedance you will find that the voltage available to the load will also drop. Use two channels in bridge arrangement and you get ~5.2W into 16r. Increase the voltage to that found in automobiles, or ~13.8V, gives ~2.6W into 8r0. A single channel amplifier working on 12Vdc can only give out <=4Vrms into a highish load.
