About the Kicker CompRT 43CWRT121

A thin sub with fat bass

If you're looking for bass for a tight space, Kicker designed their CompRT subs with compact cars, pickup trucks, and ATVs in mind. The low-profile 43CWRT121 12” subwoofer performs just like a full-size sub, but without killing all your cargo space. This high-performance CompRT sub stands less than 4" tall, so your installation options are wide open.

A thin sub with fat bass

If you're looking for bass for a tight space, Kicker designed their CompRT subs with compact cars, pickup trucks, and ATVs in mind.

This high-performance CompRT sub stands less than 4" tall, so your installation options are wide open.

Built with boom in mind

The 43CWRT121 comes equipped with a rigid injection-molded polypropylene cone that won't flex and cause distortion while you're cranking the bass. Its rubber surround will last through years of heavy use, combining with a special-design back and top plate to give you more excursion (which equals more bass) than other skinny subs.   

Made to work with many systems

This sub handles up to 500 watts RMS so make sure you've got a solid amp to power it. You can wire the dual voice coils for either 2- or 1/2-ohm total impedance, giving you more wiring options when setting up your system. This versatile sub sounds great in sealed or ported enclosures.

Important Note: If you are wiring this DVC sub for extremely low impedance, make sure that your amp is compatible. You can damage or destroy your amp by exceeding recommended minimum impedance.

Product Research

Features

Dual Voice Coils: This woofer features dual 1Ω voice coils, offering wiring flexibility. When the voice coils are wired in parallel, the woofer presents a 1/2Ω load. When the voice coils are wired in series, the woofer presents a 2Ω load.

Shallow-Mount: Kicker's CompRT series is designed to minimize depth, giving you subwoofer options where standard enclosures don't fit. The vent-less, solid-pole design allows the woofer to be mounted directly against the rear wall of a sealed enclosure.

All-Weather: Although not marine certified, Kicker describes the CompRT series as weatherproof.

Sealed Enclosures: Sealed enclosures provide the most control over a woofer and provide accurate sonic reproduction, making them suitable to all types of music. Kicker recommends sealed enclosures from 0.55 ft³ to 2.0 ft³.

Vented Enclosures: Vented (or ported) enclosures typically provide better overall efficiency than sealed so they are suitable for use with smaller amplifiers, giving you more bass output from less power. Kicker recommends ported enclosures in the following range:

  • Minimum Enclosure Volume: 1.75 ft³ with a 12-1/2" x 2-1/2" x 20" slot port
  • Maximum Enclosure Volume: 2.25 ft³ with a 12-1/2" x 3" x 20-1/2" slot port

Q
Can I run 2 of these subs and wire them to a 2ohm stable amp?

A
Yes you can and they sound really good.
[ JOHNNY  Apr 03, 2018 ]
A
If the amplifier is two channels at 2ohms. Yes!, you can connect two of these subwofers in series for each channel. I recomend a 750 watts rms for each channel.
[ EDGARD  Apr 03, 2018 ]
A
The dual 1 ohm sub can be ran in .5 ohm and 2 ohm configurations. You are looking for the dual 2 ohm subs. 1 sub with dual 2 ohms can be ran at 1 ohm or 4 ohms. So 2 dual 2 ohm subs can be ran at 2 ohms or 8 ohms.
[ TRAVIS  Apr 03, 2018 ]

I would say yes.

Thanks for your question. For information on selecting the best amp for your sub I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They will be able to help determine the differences between the amp models and help you make the best choice for your system.

Thanks for your question. Unfortunately the manufacturer does not list those specifications. You may want to check with the manufacturer directly. Their Corporate Headquarters # is 405-624-8510 or Customer Technical Support 405-624-8583. I'm sorry for not being able to confirm, but they should be able to help you.
