Installation Step; Setting High Power/High Current - Soundstream Reference 705s Owner's Manual And Installation Manual

HIGH POWER/HIGH CURRENT SWITCH
The Reference705s' subwoofer channel can be switched between "High Power" and "High
Current" modes. This allows the Reference705s to maximize power and efficiency at
impedances 1 Ohm in "High Power" mode, or down to 1/2 Ohm in "High Current" mode.
The circuit operates by selecting a set of power supply voltage rails best suited to your
particular application.
applications while the other is lower voltage designed to provide more current. Unlike other
amplifiers, Soundstream's REFERENCE amplifiers can be configured to drive virtually any
impedance and make maximum power!
To determine the setting for your application, follow the chart below:

OTHER COMMENTS:
If you blow fuses with your Reference705s, switch to the High Current
mode. If the problem persists, it is likely that the amplifier is seeing a
dead short, either in the speaker wire or in the speaker itself. Rectify
