CompRT 8" thin-profile loaded enclosure — 2 ohm

CompRT loaded enclosures deliver strong bass output in a compact footprint, now with an updated blacked-out cone. The 48TCWRT82 combines a CompRT active sub and a reFLEX passive radiator in a carpeted enclosure with a single 2 ohm terminal — ready to install under a seat, behind the rear bench or in a cargo area.

The enclosure is built from thick MDF with extensive internal bracing and custom embroidery. The CompRT's red double stitching bonds the Santoprene surround to the polypropylene woofer cone. SoloKon technology joins the cone to the vented back brace, forming a single integrated unit that cools the motor and reduces distortion.

Forced-Air Cooling helps the driver run approximately 20 per cent cooler than previous designs. Recommended amplifier power is 300W RMS.

About the Kicker 48TCWRT82

From our tech experts at CEN

The Kicker 48TCWRT82 is an 8 inch CompRT thin-profile loaded subwoofer enclosure rated at 300W RMS into a single 2 ohm terminal. It pairs a CompRT active subwoofer with a reFLEX passive radiator in a carpeted MDF enclosure measuring 49cm wide, 39cm tall and just 9cm at its shallowest point. It is designed to sit under a seat, behind a rear bench or in a cargo area.

Who it suits

This suits drivers who want meaningful bass without giving up boot space or rear seating room. The shallow 9cm top depth makes it practical for smaller vehicles or tight under-seat locations. Those wanting a self-contained powered option may prefer the Kicker Hideaway 51HS10.

Our tech experts advise

The 48TCWRT82 requires a separate mono amplifier rated at around 300W RMS at 2 ohms; the Kicker KEY500.1 is a compatible match. Check the full dimensions (49cm W × 39cm H) against your available space before purchasing. Car audio installation is priced per vehicle — visit our Nottingham fitting page for details.

Frequently Asked Questions

Q: Do I need an amplifier for this subwoofer?

A: Yes, unless it is an active (powered) subwoofer with a built-in amplifier. Passive subwoofers need an external amplifier matched to the RMS power and impedance shown in the Specification tab.

Q: What does RMS power mean?

A: RMS is the continuous power a subwoofer can handle, and it is the number that matters when matching an amplifier. Peak or max figures describe short bursts only. Match your amplifier output to the RMS rating in the Specification tab.

Q: Can CEN build or supply an enclosure and fit everything?

A: Yes. CEN supplies enclosures and offers professional installation from our Nottingham premises, including amplifier wiring. Contact us to discuss your build.

Q: Is the subwoofer included with the Kicker 48TCWRT82?

A: Yes. It is a loaded enclosure supplied with an 8 inch CompRT active subwoofer and a reFLEX passive radiator already fitted and wired to a single 2 ohm terminal.

Q: What amplifier does the 48TCWRT82 need?

A: Use a mono amplifier that is stable at 2 ohms. Kicker recommends 300W RMS for this enclosure.

Q: How deep is the 48TCWRT82?

A: It is 9 cm deep at the top and 16.4 cm deep at the bottom, 49 cm wide and 39 cm high.
