Need strong bass but don’t have the space for a full-depth sub? The KICKER 48CWRT84 CompRT 8” is built specifically for tight installs while still delivering clean, punchy low-frequency performance.
Perfect for trucks, compact cars, side-panel builds, and under-seat enclosures where mounting depth is limited but output still matters.
The CompRT line is engineered for shallow enclosures without sacrificing performance. Unlike basic slim subs, this model features a reinforced motor structure and ribbed Santoprene® surround for longer excursion and better durability.
This is real bass — not just filler.
