The dB12 is a 2 ohm stable monoblock amplifier. No matter how many woofers you choose to wire up to these models, the final impedance should not fall below 2 ohm. Please see page 14
and 15 for various speaker impedance configurations.
The dual positive and negative terminals are connected in parallel inside the amplifier. Connecting two speakers, each to one set of positive and negative terminals, will result in a parallel speaker
connection. If only connecting one pair of speaker wires, it is not necessary to use both sets of connections.
