CompRT 12" thin-profile loaded enclosure — 2 ohm
The CompRT loaded enclosure delivers deep bass in a compact footprint. It fits under a seat, behind a rear bench or in a cargo area, and comes carpeted with a single 2 ohm terminal ready to connect.
The enclosure features extensive internal bracing and thick MDF construction. The CompRT sub uses red double stitching to bond an improved Santoprene surround to a polypropylene cone. SoloKon™ technology joins the cone to a vented back brace, forming a single integrated unit that cools the motor and reduces distortion.
Forced-Air Cooling™ helps the sub run 20 per cent cooler for improved long-term reliability. The reFLEX™ passive radiator works alongside the CompRT active sub to extend low-frequency output. Recommended amplifier power is 500W RMS.
If you need a powered solution, the Kicker 48TRTP122 12 inch down-firing loaded enclosure is a related alternative worth considering.

Our tech experts advise
Pair this with a mono amplifier rated at 500W RMS; the Kicker KEY500.1 is a compatible choice. Always measure the available depth in your vehicle first, as the enclosure reaches 17.7 cm at its deepest point. Fitting is priced per vehicle — visit our car audio installation 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.

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

A: Yes. It is a loaded enclosure supplied with a 12 inch CompRT active subwoofer and a reFLEX passive radiator already fitted and wired to a single 2 ohm terminal.
Q: What amplifier does the 48TCWRT122 need?
A: Use a mono amplifier that is stable at 2 ohms. Kicker recommends 500W RMS for this enclosure.

A: It is 8.9 cm deep at the top and 17.7 cm deep at the bottom, 68.5 cm wide and 34.3 cm high.
