In bridge mode they will appear as a mono amp rated 200 watts into 8 ohms this is the most commonly misunderstood mode of operation and it requires additional circuitry to implement if the pair of amplifiers does not have the facility built in. 2x core ms157060 19 turns for 90vdc. Although class d has high efficiency for power amplifiers with high power it is better to have a fan so that the performance is more stable. A class d audio amplifier has 90 efficiency when the speaker is loaded.
