Spike Mode supports a three-subwoofer wiring arrangement using 4Ω subwoofers at 1.33Ω. GTO Signal Sense adds signal-responsive on/off behavior, while Valet Mode can limit maximum volume for everyday driving.
Installation & Compatibility Notes
Check the amplifier’s dimensions against your intended mounting space and confirm the planned subwoofer wiring matches the listed load and output rating. The amplifier accepts preamp, line-level inputs up to 6 V, and speaker-level inputs up to 20 V, allowing integration with aftermarket head units or factory radios.
For a three-subwoofer setup at 1.33Ω, use the stated Spike Mode arrangement. The ACR-1 remote level control is optional. Confirm your vehicle’s electrical requirements, mounting space, and system connections during installation planning.
