With \u003cstrong\u003e150W x 4 at 4Ω\u003c\/strong\u003e, \u003cstrong\u003e220W x 4 at 2Ω\u003c\/strong\u003e, and \u003cstrong\u003e440W x 2 bridged at 4Ω\u003c\/strong\u003e, the Q4-150ABv2 has the flexibility to drive mids, highs, and a subwoofer simultaneously — or bridge channels for more power to select speakers. Whether you’re building a full system from scratch or upgrading a factory setup, this is the amp that does it all.\u003c\/p\u003e\n\n\u003cp\u003eThe Q4-150ABv2 features \u003cstrong\u003evariable high-pass (20 Hz–5 kHz) and low-pass (50 Hz–5 kHz) filters\u003c\/strong\u003e that can be configured in a bandpass arrangement for precise frequency control across all four channels. The \u003cstrong\u003ebass boost (0–18 dB @ 45 Hz)\u003c\/strong\u003e gives you serious low-end punch when driving a subwoofer on the bridged channels. The included \u003cstrong\u003eremote gain control knob with clipping indicator\u003c\/strong\u003e lets you monitor your levels from the driver’s seat and keep your system clean.
