A thin sub with big sub bass

If you're looking for bass for a tight space, Kicker designed their CompRT subs with compact cars, pickup trucks, and even motorcycles in mind. The low-profile 40CWRT102 10” subwoofer performs just like a full-size sub, but without killing all your cargo space. This high-performance CompRT sub stands less than 3-1/2" tall, so your installation options are wide open.

Kicker 40CWRT102

This sub clocks in at less than 3-1/2" deep.

Built with boom in mind

The 40CWRT102 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 600 watts RMS so make sure you've got a solid amp to power it. You can wire the dual voice coils for either 4- or 1-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 low impedance, make sure that your amp is compatible. You can damage or destroy your amp by exceeding recommended minimum impedance.

To drive this single subwoofer, we recommend a mono amplifier rated between 450 and 900 watts RMS at 4 ohms. For more information, please refer to our article on How to Match Subwoofers and Amplifiers.

What's a component sub and why would I want one?

A component sub is simply a speaker that's designed to reproduce bass once it's installed in a compatible enclosure. Think about the impact of a movie soundtrack in a big theater or even in your own home HDTV setup. A component sub can add the same kind of power to the music in your car. And a car sub is not all about the boom that you hear on a street corner (although that's cool too) - you can pair a component sub with your choice of enclosure to get bass just the way you like it, from tight and punchy to fat and loose. And once you experience music in your car with a well-tuned subwoofer, you'll never go back.

Got two of these in a sealed downfire enclosure under the rear seat of my Chevy crew cab. Have 900w rms @ 2 ohm pushing them. They sound very good with a nice, crisp response. Would recommend these for anyone wanting subs that can handle a decent wattage amp. Looked at many other slim mount subs and these were my only real option without having to buy a new amp, etc. Been very happy with the decision.

Pros: Great sound, clean look. With the use of Kicker's U Lite (free) app, wiring was a breeze.

Cons: Haven't found any.

Excellent punchy subwoofer!

Was in the market for a shallow subwoofer for my 2012 Nissan Frontier CC and after so much research I decided to get this Kicker. Love the nice punch I get with the rest of my system. I'm running it at 1 ohm with 350 watts and is great. I'm sure I can get a more powerful amp and really get more kick out of it, but my space restrictions don't allow me.

Pros: Excellent craftsmanship, price, sound

Cons: None for me as it is what I was looking for for my small truck.

I have not had it very long but so far it hits hard and sounds good and feels like it's more the 600 watts

Pros: Very good quality and fit in the shallow box I had to use for my tundra was good !

Cons: None I can think of

Don't let "shallow mount" confuse you....if space is a factor..like below a back seat or behind a back seat of a truck these are the way to go! I use to have 2 12" woofers behind the seat of a single cab S-10 that didn't hit this hard. These subs won't disappoint. I also used the kicker 1200.1 amp- and I can't see from my rear view mirror they hit sooooo hard!

Pros: Mega sound little package

Cons: Kind of expensive to buy an amp to supply enough power

I have two of these subs in a small box underneath my backseat. They are hooked up to a 1600 watt amp.The Subwoofer hits hard at the medium to high bass pitches, but has a low raspy sound for the lower pitches, and yes, I know that 10s aren't supposed to hit that low of pitches, but overall its a good woofer.

Pros: Well built Easy to install Good shallow sub for a small box

Cons: none

2 10s 1000 watt mono kicker dx amp 525 per sub. In custom fiberglass box under back seats ram truck. I was worried about shallow subs.was running full size fosgate p3 12. But kicker subs hit really hard and sounds twice as good. Plenty loud they hit low notes pretty good.I would suggest to any one with limited space.i pound the crap out of them and they handle it very nicely.

Pros: Price,power handling,great sound,depth of speakers for trucks

Cons: So far none

Product Research

Features

Dual 2-ohm Voice Coils: This woofer features dual 2-ohm voice coils, offering wiring flexibility. When the voice coils are wired in parallel the woofer presents a 1-ohm load. When the voice coils are wired in series the woofer presents a 4-ohm load.

Tinsel Leads: CompRT subwoofers use Spiralead tinsel-lead technology; the tinsel lead wires are woven into the spider to relieve mechanical stress.

Enclosure Compatibility

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.

Sealed Enclosure Applications: 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 in the following range:

  • Minimum Enclosure Volume: 0.4 ft³
  • Maximum Enclosure Volume: 2.0 ft³

Vented Box: 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: 1.25 ft³ with a 10.5" x 2" x 20" slot port
  • Maximum Enclosure Volume: 1.75 ft³ with a 10.5" x 2.5" x 20" slot port
