With the PRS-D2000SPL, PRS-D1200SPL and PRS-D1200M’s SYNC connection, adjustment of the master amplifier also adjusts all other amplifiers in the cascade. This makes control simpler and more convenient.

*These are only a few examples of connection configurations for the PRS-D2000SPL. Ask your nearest car stereo installer or dealer about power/ground wiring and installation details for the PRS-D2000SPL, PRS-D1200SPL and PRS-D1200M.

*1 Ω minimum speaker impedance for this configuration or damage will occur. **2 Ω minimum speaker impedance for this configuration or damage will occur.

Caution: Having more than four amps in a sync configuration is not recommended.

Sine waves can put excessive stress on an audio system, so if a sine wave source is used at high output level, damage can occur.

Caution: To avoid damaging your amplifier/subwoofer system, please make sure that the continuous power output of the amplifier is lower than the nominal power handling of the subwoofer. 37
