Overview

Our take on the Kicker CompRT 43TCWRT104

Kicker's 43TCWRT104 loaded enclosure puts a thumping 10" CompRT subwoofer and a second passive sub behind the seat of a truck or in any vehicle that's low on space. The rugged sealed box was designed specifically for the subwoofer, so you can count on getting maximum performance, no matter what kind of tunes you enjoy. The second sub (called a "passive radiator") reacts to the air pressure produced by the active sub, creating lots more bass without producing any port noise.

Big bass from a CompRT sub

The 10" CompRT sub features 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.

Heavy-duty enclosure

Sturdy medium-density fiberboard ensures long-lasting performance from the enclosure, and its sealed design keeps the bass punchy and accurate, without getting sloppy. .

Crutchfield Customer Review (What's this?)

This really improved the sound in my Jeep TJ. I am quite impressed with the sound/bass quality from small sub box. I have an insta trunk for "security" and I've looked for something like this for a while. It fits perfectly in the trunk space. I recommend this product to anyone that is looking to improve sound/bass quality and that has limited cargo space in their vehicle. This is powered by a JBL GTR-601 amp.

Great fit in my Forester

John from Smithtown, NY on 6/19/2017

Crutchfield Customer Review (What's this?)

The main reason I chose this box is it fits neatly behind the back seat of my 2001 Subaru Forester, and it is short enough to not interfere with the cargo cover. Unlike any sub box I've had in the past, this leaves my cargo area wide open which is important to me as a gigging musician. I've had this set up for a few weeks now, and it did seem like it took a while for the sub to break-in as other reviewers have mentioned. It doesn't hit quite as hard as some of the other subs I've had in the past, but I feel it's a great compromise considering the minimal amount of space it occupies. I chose the 4 ohm version to pair with the JBL GTX500 amp (350w @ 4 ohms). The cone/dust cover on the sub is made of a hard plastic; if you pass frequencies above 100hz they seem to sound... plastic-y, for lack of a better word, so it's best to filter those frequencies out. Overall, I'm very happy with my purchase, and the Crutchfield service team is absolutely phenomenal.

Pros: A lot of bass in a conveniently sized box.

Cons: Frequencies about 100hz sound harsh, which might have to do with the plastic dust cap on the sub.

Features

Speaker Terminals: The spring post terminals (one pair) are mounted on the left side of the enclosure and will accept pin connectors, single or dual banana plugs (3/4" width), or bare wire up to 8 gauge.

Woofers: The Kicker 43TCWRT104 enclosure uses one 10" CompRT series subwoofer and one 10" passive radiator.

Break-in Period: Due to the complex nature of Kicker CompRT speakers, they require a break-in period in order to produce optimum low-bass response. The suspension system is very stiff out-of-the-box. Approximately two weeks of daily playing will allow the suspension to break-in and reach its optimum equilibrium. Once broken-in, the subwoofer will exhibit stronger bass performance, smoother response, and greater low-bass extension.

Dimensions:

  • Width: 23-5/8"
  • Height: 12"
  • Depth (base): 6-3/8" (7-1/8" including the subwoofer)
  • Depth (top): 3-1/2" (4-1/4" including the subwoofer)
