It has a variable low-pass crossover, a 40Hz bass boost, high-level and RCA inputs, and thermal and DC-offset protection. It suits budget builds and factory-radio upgrades where space is tight. Against name-brand monoblocks it gives up clean headroom and tuning depth, and its power ratings are optimistic next to CEA-2006-rated rivals.
