Marcus Reed founded CarAudioBlog to explain car audio in practical terms: what a specification means once it is in a real car, and what to check before you buy or install. He has 10 years of hands-on car audio experience, including speaker upgrades, subwoofer and amplifier installs, head unit replacements, DSP installation and tuning, wiring and power upgrades, and sound deadening. He writes the site's product reviews and buying guides. Where he has personally installed or tested a product, the article says so; everything else is based on research. He also oversees CarAudioBlog's editorial standards and sourcing.
