About the Kicker 46CSC684

Alexander H.

The streamlined speaker

Kicker consistently prioritizes vehicle fit along with quality in their CS Series car speakers, making them among the most popular we sell. And better fit doesn't come at the cost of better sound — you'll find several cool innovations at work here. Kicker's low-protrusion tweeter, driven by a neodymium magnet, delivers your music's highs with control and clarity. And their UV-treated poly-foam surround equips this Kicker speaker for enduring performance no matter what extremes life in your car door brings.

Consistently solid sound

Kicker's 46CSC684 6"x8" 2-way speaker serves up stellar sound using a polypropylene woofer for the lower frequencies and a PEI balanced dome tweeter for the highs. You'll get good results powering these speakers with a factory radio, but use an aftermarket car stereo or an outboard amp to enjoy classic Kicker quality with more detail and punch.

Grilles are not included; the factory grilles should be suitable for most applications.

Product Research

Features

Polypropylene Woofer Cones: The Kicker CS-series speakers feature polypropylene woofer cones, resistant to moisture and the temperature extremes found in automotive applications.

Surrounds: The ribbed polyester foam surrounds allow extended cone excursion for additional bass output and higher SPL.

Balanced-Dome Tweeters: Each speaker uses a ½" PEI (polyetherimide) balanced-dome tweeter. A balanced dome tweeter has a dome placed inside a cone, with equal reproduction area given the cone and dome sections.

Mounting Applications: Kicker describes these speakers as 6x8, but they also fit many 5x7 applications. Please enter your vehicle information to confirm fit.

Q
Do I only need two speakers for a single cab truck?
okaythanks  May 23, 2023
1 answer
A
This depends on the specific truck and your personal preferences, Caitlin. We recommend replacing all factory speaker locations with new speakers for best sound. If your single cab can use these Kicker's front and rear replacing both sets (two pairs of Kicker's) is the move! These are an excellent choice for great bass and crisp detailed mids and hi's!

They are excellent on bass. They are one of the best speakers I've used

I installed them in the front and rear of an f150 a lot better bass than stock. If you are expecting a sub you will be disappointed.

Q
What aftermarket amplifier should I pair with my Kicker 46CSC684CS Series 6x8 speakers? I have front and rear ones I just want them performing at their best. What amp should I get??
justin p  May 14, 2021

A
Thanks for your question. For information on selecting the best amp 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.

I just installed a Sony XAV-AX1000 stereo in my 2005 Ford F150. Will these speakers work with this stereo?

they fit perfectly in all 4 of my doors in my 2010 f150 super crew. I'm not sure about your 2005 but the Crutchfield website should easily be able to tell you if you enter your truck info

Yes those Kicker speakers should be efficient enough to work well with a factory head unit.

Q
I have a 1998 Ford Ranger. I put in a new JVC radio and was trying to figure out if I should replace the factory speakers. The JVC provides 22watts to each speaker. I've seen some reviews with people putting these in late 1990s vehicles and wanted to see if it was worth it or not. I'm interested specifically in the bass output. I don't need shake you windows bass, but the factory speakers have absolutely nothing. How much bass over factory speakers?

I've been very happy with the Kickers I bought, so much so I plan on getting a second pair for the rear door speakers. Bass is very good, hard to say how much over OEM but I can say without a doubt the Kickers improved bass & overall sound quality exceeded my expectations!
cecile  Aug 15, 2019

They are a good quality speaker, but u won't hear much difference in bass ,if any, over factory speakers. U would need to run them off a amplifier to get what your looking for.
david  Aug 14, 2019
A
I put them in a 97 ranger. They sounded pretty good with an upgraded JVC radio. I recently upgraded to an Alpine 650 with the 450 add on amp. They sound a lot better with the amp. Sorry to say though that the bass is just not there. I was looking for the same thing as you, a bit of bass but nothing crazy. Im contemplating an all in one amp mounted under the seat like the Sound Ordanance B-8PTD
nicholas  Aug 14, 2019

Autocorrect got me. Dynamat
douglas w  Aug 13, 2019

Crutchfield sent 4kickers with a kenwood stereo.plenty of bass. Had interior out.put suns mat everywhere. Highly suggest dynamic mat the roof! Lower temperature radiating through roof and really helped reduce noises.
douglas w  Aug 13, 2019

I can't answer your question directly since these replaced my front speakers in a 2007 mustang with the shaker 500 system. The shaker 500 system has front sub-woofers from the factory. I can say the clarity is much better than stock.
