Installation Notes

• Proper final subwoofer impedance must be confirmed before wiring the two enclosures to the amplifier. The supplied RS-SB12 specifications do not state each enclosure's final impedance.

• The R2-A150M is rated for 1,500 watts RMS at 1 ohm, 1,200 watts RMS at 2 ohms, and 700 watts RMS at 4 ohms.

• Do not assume a 1-ohm final system load without confirming the actual impedance and wiring configuration of both enclosures.

• The supplied description states that the R2-A150M is ready for the RUX-KNOB.2 , while the separate RUX-KNOB.2 compatibility section specifically lists MRX-M50, MRX-M100, MRX-V60, PDX-M12, and PDX-M6. Verify RUX-KNOB.2 compatibility with the R2-A150M before installation or fulfillment.

• The supplied source refers to RS-SB12 enclosures but also references R2-SB12V when describing ProLink operation. Verify the exact enclosure model before fulfillment.

• Additional 4-gauge amplifier power wiring, fuse protection, ground cable, signal cables, speaker wire, and installation hardware may be required and are sold separately unless otherwise included.

• Verify cargo space for two approximately 17" x 25" x 15" enclosures before ordering.

• Professional installation is recommended for proper impedance wiring, amplifier setup, gain adjustment, crossover configuration, and safe power-system installation.
