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.

MULTIPLE SPEAKERS OR VOICE COILS SERIES WIRED
SX.1 series amplifiers are capable of powering multiple speakers or voice coils wired in
series as long as the minimum impedance does not drop below 2 ohms (SX650.1) or 1 ohm
(SX1250.1).
