Our verdict
The Kicker 43CWRT82 CompRT is a high-power shallow-mount car subwoofer that squeezes 600W handling into a 3-inch mounting depth, making it a serious upgrade option for vehicles with no room for a traditional enclosure. This is a car audio product, not a home theater component.

The overall score is owner satisfaction weighted by how many reviews back it, so a high rating from few reviews counts for less. The bars below show where this model stands against the other AV receivers and amplifiers, soundbars, home theater speakers, subwoofers, surround sound systems and Blu-ray players we track in this category on price, popularity and size. Context, not marks against it, and our read of the data, not a lab test.
Overview
The Kicker 43CWRT82 is part of Kicker's CompRT series, which are purpose-built shallow-mount subwoofers for applications where mounting depth is severely restricted. At a mere 3-inch mounting depth, it can be installed in doors, under seats, or in custom enclosures that a standard 8-inch driver simply would not fit.
The 600W power handling puts it firmly in the enthusiast category. It connects via RCA, standard for car audio systems, and weighs 7.3 lbs. At 266 reviews with a 4.6-star average, buyer satisfaction is high, particularly from buyers who specifically needed the shallow profile without sacrificing output.
Because this is a passive driver requiring an external amplifier, total system cost is higher than an all-in-one powered subwoofer. Budget for a compatible mono amplifier to get it running.

Performance notes
The 43CWRT82 handles 600W with an 8-inch driver in a 2.95 x 2.95 x 6.3 in footprint at just 3-inch mounting depth. RCA input requires a line-level signal from a car head unit or amplifier pre-out. The CompRT designation signals Kicker's shallow-mount optimized suspension and motor design intended to compensate for reduced enclosure compliance.
What buyers say
At 4.6 stars from 266 reviews, the CompRT 8 earns strong marks among car audio buyers. The consistent theme in positive reviews is surprise at how much output a shallow-mount driver delivers. The main complaints come from buyers who underestimate amplifier requirements or attempt sealed-box builds with inadequate volume.

Frequently asked questions
Does the Kicker 43CWRT82 include an amplifier?
No, the 43CWRT82 is a passive subwoofer driver only. You will need a separate mono or two-channel car amplifier capable of delivering 300 to 600W at the appropriate impedance. Check the driver's impedance spec before pairing an amplifier to ensure a proper match.
Can the Kicker 43CWRT82 be used in a sealed or ported enclosure?
Yes, the CompRT is designed for sealed enclosures, which Kicker provides specific volume recommendations for in the technical specs. Ported builds are possible but sealed is the preferred application for shallow-mount drivers because it gives more control over cone movement in a reduced cabinet volume.
