The Stetsom Bravo HQ 800.4 is built for car audio enthusiasts who want stronger four-channel power, useful tuning control, and an amplifier that still stays compact enough for real-world installs. Stetsom says the Bravo Full line was developed for people seeking maximum performance and quality in amplifiers, and the HQ 800.4 gives you a noticeable step up in output for speakers, mids, highs, or bridged applications without forcing you into a huge chassis.

This amp gives you four independent channels and solid power whether you are running 2 ohm stereo loads, 4 ohm speakers, or bridging channels for more output. At 14.4 volts it is rated for 4 x 250 watts RMS at 2 ohm and 4 x 170 watts RMS at 4 ohm. At 12.6 volts it is rated for 4 x 200 watts RMS at 2 ohm and 4 x 130 watts RMS at 4 ohm, with 2 x 400 watts RMS bridged at 4 ohm. That makes it a strong fit for louder speaker builds, pro-audio-style mids and highs, or installs where you want one compact amp to do a lot of work.

One of the better things about the Bravo HQ 800.4 is how flexible it is for tuning. Stetsom includes variable low-pass and high-pass crossovers from 50 Hz to 2.3 kHz, plus a wide listed frequency response. The page says the Bravo Full line offers response suitable for subwoofers, woofers, drivers, and tweeters, which means this amplifier can be used in a lot of different kinds of projects depending on how you configure the channels. If you are building a strong daily speaker setup or need serious four-channel power in a clean package, this is the kind of amp that makes sense.

Whether you are powering a full set of door speakers, running mids and highs in a louder build, or bridging channels for more output where needed, the Stetsom Bravo HQ 800.4 gives you strong multichannel power, tuning flexibility, and a compact size that is easier to work with than a lot of larger amps.
