Subwoofer Specifications

Subwoofer Series
Each subwoofer manufactured is part of a series. This is the name of the subwoofer's series.
Comp-RT / CRT (Kicker)
Subwoofer Size
Refers to the diameter of the subwoofer, measured in inches.
Voice Coil(s)
Dual voice coil subs have more wiring flexibility than single voice coils subs; however, single voice coil subwoofers provide easier hookup options for wiring multiple subwoofers in parallel or series. You may also run a dual voice coil (DVC) sub in parallel, series, or combination. A quad voice coil has four voice coils and is equal to two dual voice coil subwoofers as far as wiring goes.
Impedance (Per Voice Coil)
The load value (in ohms) that the speakers present to the amplifier per voice coil - the amount of resistance to the current flow. This is a key specification as subs wired in parallel or low impedances can create problems with your amplifier and potentially void all warranties. We encourage you to ask our support department prior to purchase if you do not understand which impedance level will suit your application best.
2 ohms
RMS Power Handling
The RMS power is the amount of power the speaker requires to operate safely and properly. RMS Power Handling refers to the amount of power a speaker can handle on a continuous basis. We recommend powering your speakers or subwoofer with 80%-120% of its recommended RMS rating. The RMS power handling specification is typically rated per speaker unless otherwise noted.
400 watts
Peak Power Handling
Peak power handling refers to the amount of power a speaker can handle during a brief musical burst. The RMS power range figure is a much more reliable rating for determining the speaker's power requirements. The Peak power handling specification is typically rated per speaker unless otherwise noted.
800 watts
Woofer Composition
Lightweight woofer cone materials are essential for efficient operation. Poly cones produce exceptional sound and are sturdy against various changes in temperature. Paper cones are very efficient, and when treated for moisture resistance, will perform at a high level. Poly refers to polypropylene, which is thermoplastic or fibers that are polymers of propylene. IMPP refers to injection molded polypropylene, a commonly used process and material in speakers.
Woofer Surround
A speakers surround is part of the suspension system. The surround protects the cone and prevents it from being displaced as it flexes out from the basket. It is usually made of a durable material like treated foam or rubber in order to withstand the strenuous job of producing bass frequencies.
Santoprene Rubber
An efficiency or sensitivity rating tells you how effectively a speaker converts power into sound. The higher the number, the more efficient the speaker and the louder it will play with the same input power. An efficient speaker helps you maximize your available power. Most sensitivity ratings measure the speaker's output with 1 watt of input, 1 meter from the speaker. Some speakers' sensitivity is measured with 2.83 volts of input, instead of 1 watt.
Efficiency (1w/1m) is not an accurate indicator of a subwoofer's output capability and should not be used as a comparison to other speakers or subwoofers to determine which one is "louder".
87.2 dB

Enclosure Specifications

Box Type
Represents the style of the enclosure. Be sure to purchase the appropriate enclosure type and internal volume that will be compatible with your subwoofer's recommendation.

Sealed - Sealed boxes are those that have no holes or vents in it. The only hole in a sealed box is where the subwoofer is installed. Smaller sealed boxes require more power than a larger sealed box. They provide a tight, accurate bass, while the larger sealed enclosures provide a "boomier" and louder bass.

Ported / Vented - Ported/Vented Enclosures provide an even boomier, louder bass, but less accurate then a small, sealed box. Ported enclosures typically require more airspace per sub and also less power output from an amplifier to perform correctly.

Bandpass - Bandpass enclosures make subwoofers perform efficiently, but loose. The bass is not as "boomy" as a ported enclosure nor as punchy as a sealed enclosure. Bandpass enclosures work well with lower to mid-level subwoofers.
Number of Subs/Speakers
This value represents the number of speakers or subwoofers that the enclosure accommodates.
Box Style/Shape
The box style or shape refers to the actual shape of the box. Square and rectangular boxes are straight-edged boxes on all sides, whereas hatchback and truck style enclosures feature an angled front or back design that allows for installation in places short on depth such as single cab pickup trucks. You can also use such enclosures in hatchback cars or other vehicles where space is a premium. Tube and cylinder shaped boxes were made popular by Bazooka and are a great option for those looking for a nice amount of bass without sacrificing lots of space. They may even fit in locations that slim truck boxes cannot fit in. If the enclosure is vehicle specific, we encourage you to read the product description to find out which vehicles the enclosure is made for.
Truck Style, Slim with Angled Front
The height of the item, measured from top to bottom, in inches.
The width of the item from left to right (side-to-side) measured in inches.
The front-to-rear depth of the item, in inches. If the item is angled or slanted, this value is the bottom measurement.
Second Depth
The second depth is used only when the box is slanted or angled. This value is the top measurement and it is measured in inches.
Box Exterior Color
The color of the enclosure's exterior/outer finish.
Box Finish
The material used on the outside of the box. Most boxes are carpeted to prevent exterior scratches; however vinyl is popular as it can often be color-matched to a near exact look of your leather factory interior.

Solid slim sub

June 3, 2015

Great sub! It took about a week to get the suspension broke in but after that it has been amazing considering its size. I had initially purchased the wrong ohm and was able to return it get the right one. Great customer service.

Perfect solution for king-cab pickup

June 1, 2015

Rewired from standard 4 ohm to 1ohm to mate with sub channel from a Polk D5000.5 amp. Strongly suggest you order the Kicker Grill protector (it appears to fit all Kicker 10" subs--has same screw pattern/radius). I added a cargo handle to the top and wired a Neutrik pro-audio heavy duty speaker connector (partsonline) to make it fast/easy to pull the Sub out if parking the truck in some sketchy place!
Hence only 4 stars for features/ease of use--although with my mods, I'd give it 5!
No idea about durability, yet.
Tight & precise, not an obnoxiously-boomy type of bass. Listen to the intro to Van Halen's "Hot for Teacher". The drums and cymbals sound killer--I've played drums for 40+ years and know what they sound like!

2015 Ford F150 system setup

June 6, 2016

I bought this to fit my 2015 F150 super cab. It fits perfectly under the back seat and is a breeze to setup. It took me 10 minutes from start to finish.

Before this sub I had a 10 inch Boston G2 in my truck and that thing was a house. This sub does not hit as hard as the G2, but for a pancake that fit easily it is awesome.

Can this be rewired to 4 ohm configuration?
A shopper on Jan 27, 2015
Best Answer: Hello,

No. The Kicker 40TCWRT102 is equipped with a Dual-4ohm CompRT . Despite what our description currently shows - which has already been reported - the driver is WIRED IN PARALLEL TO A 2ohm LOAD. This means, hypothetically, if you were to open up the enclosure to re-wire the driver, your only other option would be to wire in SERIES to an 8ohm Load. Unfortunately, there isn't an alternate solution to reach the final load you seek.

You may want to consider putting together such a setup. Which means going with the Kicker 40CWRT102 in an 10ANTCM enclosure. This can very well be wired up to a 4ohm final load.
