If you’re thinking of big bass in a small space, you should be thinking about Kicker. Kicker’s 43TCWRT672 loaded enclosure places a 6-3/4″ CompRT sub and a passive radiator behind a truck seat or anywhere space is tight. The passive radiator generates plenty of extra bass, so this box will definitely put some muscle in your music. The rugged box was designed as a perfect match for the sub, so you can count on getting maximum performance, no matter what kind of music you prefer.
