Built for enthusiasts who demand serious sub-bass power without sacrificing install space, the VL3000D is the step-up choice in the Alliance Audio VL mono lineup, doubling the 1-ohm RMS output of the VL1500D while maintaining the same ultra-slim, under-seat-friendly form factor. Its high-efficiency \u003cstrong\u003eClass D topology\u003c\/strong\u003e runs approximately 80% more efficiently than traditional Class A\/B designs, keeping thermal output low and sustained power delivery consistent even during extended high-volume sessions.\u003c\/p\u003e\u003cp\u003eThe VL3000D is loaded with precision tuning controls including a variable \u003cstrong\u003elow-pass filter (50Hz–220Hz)\u003c\/strong\u003e, a \u003cstrong\u003esubsonic\/high-pass filter (10Hz–50Hz)\u003c\/strong\u003e, and a \u003cstrong\u003e0–12dB variable bass boost\u003c\/strong\u003e for dialing in your exact sub-bass character without an external processor. With a \u003cstrong\u003edamping factor of 150\u003c\/strong\u003e and a \u003cstrong\u003esignal-to-noise ratio of 92dB\u003c\/strong\u003e, it delivers tight, controlled woofer movement and clean, low-noise amplification at every volume level. The wide \u003cstrong\u003einput sensitivity range of 0.2V–9V\u003c\/strong\u003e ensures seamless integration with factory head units and aftermarket source units alike, and the included \u003cstrong\u003ewired sub-level remote\u003c\/strong\u003e lets you adjust bass output from the driver's seat on the fly. Max current draw is 85A; Alliance Audio recommends a 60A fuse for safe, reliable operation.\u003c\/p\u003e\u003cp\u003eAt \u003cstrong\u003eTrinity Car Audio\u003c\/strong\u003e, the VL3000D is an ideal power plant for a single high-excursion 12\", 15\", or 18\" subwoofer in a ported enclosure, or for pushing a pair of smaller woofers wired to a 1-ohm or 2-ohm load.

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 the subsonic filter set to 20–25Hz is typically sufficient. Wire the amp with a minimum 4-gauge power and ground cable — for builds pushing the full 750W RMS, consider upgrading to 1\/0-gauge for reduced voltage drop and maximum sustained output. Install a 60A inline fuse within 18 inches of the battery per Alliance Audio's recommendation.\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\u003eVL3000D\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\u003e3000W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRMS Power @ 1Ω \/ 14.4V\u003c\/td\u003e\n\u003ctd\u003e750W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRMS Power @ 2Ω \/ 14.4V\u003c\/td\u003e\n\u003ctd\u003e375W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRMS Power @ 4Ω \/ 14.4V\u003c\/td\u003e\n\u003ctd\u003e187.5W\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\u003e92dB\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\u003e85A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRecommended Fuse Rating\u003c\/td\u003e\n\u003ctd\u003e60A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions (W × L × H)\u003c\/td\u003e\n\u003ctd\u003e14.7 cm × 22.6 cm × 4.8 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e2.2 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\u003eHow does the VL3000D compare to the VL1500D?\u003c\/strong\u003e\u003cbr\u003eThe VL3000D delivers 750W RMS at 1 ohm — exactly double the VL1500D's 375W RMS — in a similarly compact chassis.
