SX .1 Series Amplifiers

AMPLIFIER STRAPPING

SX.1 series amplifiers are capable of being strapped together to provide twice the power into twice their rated minimum impedance. Only like model amps can be strapped together. In other words, the SX650.1 can only be strapped to another SX650.1 and the SX1250.1 can only be strapped to another SX1250.1.

NOTE...

4 ohm minimum impedance for SX650.1 when strapped.

2 ohm minimum impedance for SX1250.1 when strapped.

1.) Wire both amplifiers to 12 volt power, ground and remote.

2.) Connect a RCA cable from the source unit to the RCA Input jacks on the primary amp.

3.) Use the supplied 1/8 inch mono cable to connect the Amp Strapping Out jack of the primary amplifier to the Amp Strapping In jack of the secondary amplifier.

4.) Use a short piece of heavy gauge wire (12Ga, 10Ga, 8Ga) to connect the Speaker negative terminals of both amps together.

5.) The primary amplifier’s positive terminal is used for the positive speaker connections.

6.) The secondary amplifier’s positive terminal is used for the negative speaker connections.
