Larger electrical upgrades should be based on the vehicle and the total system—not only the amplifier’s advertised wattage.\u003c\/p\u003e\n\n\u003ch2\u003eSubwoofer and Impedance Matching\u003c\/h2\u003e\n\n\u003cp\u003eBefore ordering, confirm that the subwoofer voice coils can be wired to a final load of 1, 2, or 4 ohms. The amplifier should never be connected below its published 1-ohm minimum impedance.\u003c\/p\u003e\n\n\u003cp\u003eChoose a subwoofer or subwoofer combination with realistic RMS power handling for the amplifier’s output at the final wired impedance. Enclosure design, impedance rise, voltage, tuning, and the musical signal will affect the power the subwoofer receives in actual use.\u003c\/p\u003e\n\n\u003ch2\u003eGain and Crossover Setup\u003c\/h2\u003e\n\n\u003cp\u003eGain is not a volume control. Set the gain to match the clean output voltage of the radio, DSP, or line-output converter. Excessive gain, bass boost, or a clipped input signal can overheat the amplifier and damage the connected subwoofer.\u003c\/p\u003e\n\n\u003cp\u003eUse the low-pass filter to control the upper frequencies sent to the subwoofer. When using a ported enclosure, set the adjustable subsonic filter around the enclosure design and tuning frequency to help protect the subwoofer from excessive movement below the usable range.\u003c\/p\u003e\n\n\u003cp\u003eFor more setup help, read our guide explaining \u003ca href=\"https:\/\/audiosellerz.com\/blogs\/audio-sellerz-blogs\/how-to-set-amp-gain-the-right-way-without-cooking-your-gear\" style=\"color:#0066cc;text-decoration:underline;\"\u003ehow to set amplifier gain correctly\u003c\/a\u003e.\u003c\/p\u003e\n\n\u003ch2\u003eSky High FXB 1000.1 Frequently Asked Questions\u003c\/h2\u003e\n\n\u003ch3\u003eHow much power does the FXB 1000.1 produce?\u003c\/h3\u003e\n\n\u003cp\u003eAt 14.4 volts, it is rated for 1,050 watts RMS at 1 ohm, 650 watts RMS at 2 ohms, and 320 watts RMS at 4 ohms.\u003c\/p\u003e\n\n\u003ch3\u003eIs the FXB 1000.1 stable below 1 ohm?\u003c\/h3\u003e\n\n\u003cp\u003eNo below-1-ohm rating is published for this amplifier. Its listed minimum impedance is 1 ohm, so it should not be wired below that load.\u003c\/p\u003e\n\n\u003ch3\u003eDoes the amplifier include a bass knob?\u003c\/h3\u003e\n\n\u003cp\u003eYes.
