For maximum output at 1 ohm, wire dual 2-ohm voice coil subs in parallel, or run multiple subs wired to achieve a 1-ohm final load. For 0.5-ohm operation, wire multiple high-excursion subs in parallel to achieve the target impedance and verify your subwoofers are rated for the increased output at that load.\u003c\/p\u003e\n\u003cp\u003eAt 7,500W RMS, a serious electrical build is non-negotiable. A Big 3 upgrade in 1\/0 AWG or larger is the absolute minimum. A high-output alternator (300A+ for sustained full-output operation), a secondary AGM or lithium battery, and a dedicated capacitor bank are strongly recommended to maintain voltage above 13.5V under sustained load. Use a 1\/0-gauge power and ground wiring kit with appropriate inline fusing sized for the amp's current draw. Set your subsonic filter to protect your subwoofers from over-excursion in ported enclosures, and use the 0–180° phase control to align your sub stage with your front stage for maximum impact.\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\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eRMS Power @ 1Ω (14.4V)\u003c\/td\u003e\n\u003ctd\u003e7,500W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRMS Power @ 2Ω (14.4V)\u003c\/td\u003e\n\u003ctd\u003e4,000W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRMS Power @ 4Ω (14.4V)\u003c\/td\u003e\n\u003ctd\u003e2,500W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMinimum Impedance\u003c\/td\u003e\n\u003ctd\u003e0.5Ω Stable\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eImpedance Warranty\u003c\/td\u003e\n\u003ctd\u003e0.5Ω (1 Year)\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\u003eFinish\u003c\/td\u003e\n\u003ctd\u003eRed\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFrequency Response\u003c\/td\u003e\n\u003ctd\u003e10Hz – 250Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePhase Control\u003c\/td\u003e\n\u003ctd\u003e0° – 180°\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTHD\u003c\/td\u003e\n\u003ctd\u003e\u0026lt; 0.01% @ 4Ω\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Sensitivity\u003c\/td\u003e\n\u003ctd\u003e0.2V – 6V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRCA Inputs\u003c\/td\u003e\n\u003ctd\u003eTiffany-Style Locking RCA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Input Gauge\u003c\/td\u003e\n\u003ctd\u003e1\/0 AWG\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOverall Length\u003c\/td\u003e\n\u003ctd\u003e27\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHeatsink Length\u003c\/td\u003e\n\u003ctd\u003e25.625\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWidth\u003c\/td\u003e\n\u003ctd\u003e10.5\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHeight\u003c\/td\u003e\n\u003ctd\u003e2.75\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWarranty\u003c\/td\u003e\n\u003ctd\u003e1 Year Standard \/ 2 Year Extended Available\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\u003eQ: Is the Ruthless Audio 7500.1 Red really 0.5-ohm stable?\u003c\/strong\u003e\u003cbr\u003eA: Yes — the 7500.1 Red is rated, stable, and warranted at 0.5 ohms.
