Built on a brand-new board engineered to support up to \u003cstrong\u003e18V\u003c\/strong\u003e, the Q1-4500v2 delivers \u003cstrong\u003e4,670W RMS at 1 ohm (14.4V)\u003c\/strong\u003e — and when pushed with a high-voltage electrical system, it climbs all the way to \u003cstrong\u003e7,140W RMS at 18V\u003c\/strong\u003e. That’s not a typo. SoundQubed designed this amplifier around three core principles: \u003cstrong\u003eReliability, Affordability, and Longevity\u003c\/strong\u003e — and the Q1-4500v2 exceeds expectations on all three. Korean-built, compact, and engineered to be pushed to the limits every single day.\u003c\/p\u003e\n\n\u003cp\u003eThe Q1-4500v2 is a \u003cstrong\u003eClass D monoblock\u003c\/strong\u003e operating across a wide \u003cstrong\u003e9V–18V\u003c\/strong\u003e working voltage range, with a maximum amperage draw of \u003cstrong\u003e800A\u003c\/strong\u003e.

Input sensitivity runs from \u003cstrong\u003e0.15V to 5V\u003c\/strong\u003e for compatibility with virtually any head unit or DSP. With a signal-to-noise ratio greater than \u003cstrong\u003e94 dB\u003c\/strong\u003e and a damping factor greater than \u003cstrong\u003e310\u003c\/strong\u003e, the Q1-4500v2 is as clean as it is powerful.
