For channel 5, a dual 2-ohm DVC subwoofer wired in parallel to 2 ohms will deliver the full 510W RMS output. Set the high-pass filter on channels 1–4 between 80–100Hz to protect your speakers, and the low-pass filter on channel 5 between 80–120Hz for clean subwoofer integration. Use the phase control to align the subwoofer's output with your front stage — start at 0° and adjust by ear. Wire the amp with a minimum 4-gauge power and ground cable; for builds pushing all five channels at full output, consider upgrading to 1\/0-gauge to minimize voltage drop.

For a ported enclosure build, set the low-pass filter between 80–120Hz and the subsonic filter at 25–35Hz to protect the woofer from over-excursion below the box's tuning frequency. For sealed enclosures, a low-pass setting of 80Hz with no subsonic filter is typically sufficient. Wire the amp with a minimum 4-gauge power and ground cable, and use the included remote to fine-tune bass output for different music genres on the fly.\u003c\/p\u003e\n\n\u003ch2\u003eFull Specifications\u003c\/h2\u003e\n\u003cdiv style=\"overflow-x:auto;\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eAlliance Audio\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eVL1500D\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAmplifier Class\u003c\/td\u003e\n\u003ctd\u003eClass D\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eChannels\u003c\/td\u003e\n\u003ctd\u003e1 (Monoblock)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePeak Power\u003c\/td\u003e\n\u003ctd\u003e1500W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRMS Power @ 1Ω \/ 14.4V\u003c\/td\u003e\n\u003ctd\u003e375W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRMS Power @ 2Ω \/ 14.4V\u003c\/td\u003e\n\u003ctd\u003e187.5W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRMS Power @ 4Ω \/ 14.4V\u003c\/td\u003e\n\u003ctd\u003e93.75W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFrequency Response\u003c\/td\u003e\n\u003ctd\u003e15Hz – 250Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSignal-to-Noise Ratio\u003c\/td\u003e\n\u003ctd\u003e91dB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Sensitivity\u003c\/td\u003e\n\u003ctd\u003e0.2V – 9V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDamping Factor\u003c\/td\u003e\n\u003ctd\u003e150\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Voltage\u003c\/td\u003e\n\u003ctd\u003e9V – 16V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHigh Pass \/ Subsonic Filter\u003c\/td\u003e\n\u003ctd\u003e10Hz – 50Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLow Pass Filter\u003c\/td\u003e\n\u003ctd\u003e50Hz – 220Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBass Boost\u003c\/td\u003e\n\u003ctd\u003e0 – 12dB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax Current Draw\u003c\/td\u003e\n\u003ctd\u003e45A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMusic Current Draw\u003c\/td\u003e\n\u003ctd\u003e24A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFuse Recommendation\u003c\/td\u003e\n\u003ctd\u003e30A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions (W × L × H)\u003c\/td\u003e\n\u003ctd\u003e14.7 cm × 20.8 cm × 4.8 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e1.8 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eWhat size subwoofer pairs best with the VL1500D?\u003c\/strong\u003e\u003cbr\u003eThe VL1500D works well with 10\", 12\", or 15\" subwoofers rated between 150–375W RMS.

The wide input sensitivity range (0.2V–9V) makes the VL1500D fully compatible with low-voltage factory outputs.
