I have two pairs of Kg-4s that I'm considering powering with two Harman Kardon Citation 19 Power Amps. The Citation 19's can be operated in bridge mode so that both channels operate as one. HK warns against operating in bridge mode for speaker loads at 4 ohms since it may cause the amplifier's current limiting circuits to operate and distort the signal. The KG-4 is rated at 6 Ohms. If I operate both amps in bridge mode (one for each channel), but with two speakers per amplifier, will this potentially cause a high-current situation? The manual says each amplifier will deliver 3.7 Amps to a 16 Ohm load, and 6.3 Amps to a 8 Ohm load in bridge mode. If yes, should/ can I add fuses between amplifiers and speakers? Thanks!
