Stetsom says the Bravo HQ line was developed for people looking for both performance and sound quality, using a compact, discreet, and quiet amplifier design. That makes the HQ 400.4 a strong option for speaker upgrades, full-range systems, and installs where space matters but you still want dependable four-channel output. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp data-start=\"782\" data-end=\"1275\"\u003eThis amp gives you four output channels and is also compatible with bridge mode, which opens up more flexibility depending on how you want to power the system. At 14.4 volts it is rated for 4 x 105 watts RMS at 2 ohm, 4 x 60 watts RMS at 4 ohm, or 2 x 180 watts RMS bridged at 4 ohm. That gives you room to run mids and highs in a full active-style setup, power door speakers with headroom, or bridge channels for stronger output in the right application. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp data-start=\"1277\" data-end=\"1886\"\u003eOne of the best things about this amp is how flexible it is for tuning. The Bravo HQ 400.4 includes variable high-pass and low-pass crossovers from 50 Hz to 2.3 kHz, plus level controls for more precise adjustment. Stetsom also lists a wide 5 Hz to 30 kHz frequency response, which is why this amplifier can be used in a variety of projects with subwoofers, woofers, drivers, and tweeters. For someone building a clean everyday system or a compact multichannel setup, this is the kind of amp that gives you useful power and useful control without taking up a lot of room. \u003cspan
