Два моноблока мостом.

Не на той, что я дал. В инструкции к усилителю есть книжка - tech tips со всякими схемами.
Вот, что мне надо, помогите разобраться.

Then bridging 2 hich current amplifiers, you must use one of the mono-block style amplifiers and they must be identical model. The RCA input from the source unit will go into the Master amplifier. Make sure this amplifier’s master/slave switch is set to master. Then connect the supplied RJ-12 cable between the amplifiers. The second amplifier with no RCA connection made to it must have its master/slave switch in the slave position. The + of the master amplifier is then used as the + connection of the subwoofer. The + of the slave amplifier is used as the – connection for the subwoofer. The - terminal connections on each amplifier are the connected together. You can then adjust both amplifiers by using only the control on the master amplifier. When bridging it is very important to ensure that the resulting ohm load of the subwoofers is equal to or greater than 2 ohms.

Приблизительный перевод - Подключать можно только два идентичных усилка. RCA с головы подключается к главному усилителю. Убедитесь, что на главном усилителе переключатель "master/slave" (главный/ведомый) в положении master (главный). Соедините кабелем RJ-12 усилители. Ведомый в положение slave. Плюс главного усилителя (это про выходы на саб) к плюсу саба. Плюс ведомого усилителя к минусу саба. Минусы усилителей соедините между собой. Все настройки с главного усилителя. При таком подключении минимальное сопротивление нагрузки - 2 ома.
