Product Information

Add Some Much-needed Bass

It doesn’t matter if you listen to blues, or heavy metal, or hip hop – there is a lot more to music than just listening to it. What else could there be? How about feeling the music? That’s part of what bass is all about. It immerses you more into your favorite tunes and quadruples the enjoyment factor. The Kicker 40CWD84 is sure to please even the most discerning of listeners.

You’ve Got Options

Kicker designed their CompD subwoofers to be versatile. This can be noted in their dual voice coil design which will allow you to wire up one or more 40CWD84 subwoofers in a couple of different ways to maximize the power coming from your amplifier. The 8” subwoofers also sound fantastic in either a sealed enclosure or a ported enclosure – the choice is yours.

Allow Us To Suggest…

To properly power this car subwoofer (assuming you are using only a single 40CWD84 subwoofer in your setup), we would recommend a single-channel (or monoblock) amplifier that is stable at 2 ohms. Ideally, the power output of this amplifier at 2 ohms would be around 200 watts.
