Our take on the Kicker Bullfrog® BF400 Music System by Crutchfield's Ralph Graves
Waterproof and dust-proof
The party's in the bag
When I brought the Kicker Bullfrog BF400 to my desk to check it out, a co-worker jokingly asked, “Is that your lunch bag?” “No,” I replied, dropping the 8.6-pound speaker on my desk. “It's a party waiting to happen.” And so it is. This portable Bluetooth speaker kicks out sound as brawny as its waterproof casing. And that's just for starters.
The BF400 features two 3" full-range speakers with two3" x 4" passive radiators for enhanced bass. One speaker/radiator pair faces front, and the other faces rear, generating a 360° soundfield. The system has a nice, tight sound. And you'll hear it loud and clear when used outdoors.
The speaker's casing has an IP66 rating, meaning it's waterproof and dust-proof. While you shouldn't jump into the pool with your BF400, it will withstand the splash of your cannonball while sitting poolside. And if your BF400 gets splattered with dirt or mud, you can just hose it off.
FM radio and auxiliary input
A built-in FM tuner gives you even more listening options. The BF400 comes with a detachable FM antenna to improve reception. You can also play music from other portable devices through the JUMPs auxiliary input jack.
Kicker Connect App
Download Kicker's free control app to your Apple® or Android™ device and really take control of your BF400. With it, you can pair two Bullfrog music systems for two-channel stereo.
The app also lets you save your favorite FM stations as presets. You can even label the stations to make them easier to find. For example, instead of memorizing call letters, just label your sports station preset “sports.”
Power to spare
The speaker's built-in rechargeable battery gives you up to 20 hours of portable operation. The JUMP comes with its own USB charging cable. Just plug it into a computer or a spare AC/USB adapter to recharge. And you can keep your smartphone charged through the JUMP's USB charging port.

Great speaker! The app you download with it makes it so much better. A little on pricey side, but it's pretty loud for sure an still sounds very crisp! Not much bass, but overall a good speaker. Haven't used the radio option yet and probably won't.

Features and Specs
|NFC Touch Pairing||No|
360 Degree Sound: The Kicker Bullfrog BF400's unique driver design gives you speakers on both sides of the unit for 360 degree sound. There is one round 3" full-range driver and one oval 3"x4" passive radiator on each side of the speaker. The two 3" full-range drivers are powered by a built-in 30-watt amplifier.
Water & Dust Resistant (IP66 Rated): Its IP66-rating means the Kicker Bullfrog BF400 offers complete protection against dust and power water spray on all sides. So you can feel confident when taking this speaker system to the pool, beach or camping. The rubber cap that covers the Power, Aux, USB, and Antenna port needs to be installed for the speaker's IP66-rating.
Note: Even though the Kicker Bullfrog BF400 is water & dust resistant, it cannot be fully immersed in water (this will cause permanent damage to the speaker).
Bluetooth Audio Streaming: The Kicker Bullfrog BF400 offers built-in Bluetooth with support for A2DP & AVRCP, so you can wirelessly stream stored music and music apps from your smartphone, tablet, laptop, or computer (including Apple, Android, Windows, and Mac) to the speaker system. You'll even be able to control basic music playback functions such as Play/Pause & Previous/Next Track from the Bullfrog BF400.
- 100' Wireless Range: The Kicker Bullfrog BF400 system combines Bluetooth with its own proprietary wireless technology for an amazing 100' wireless Bluetooth range.
- Multi-Device Pairing & Auto-Connect: You can pair the Bullfrog BF400 with up to 5 Bluetooth source devices, but only one can be connected at a time for playback. It will automatically reconnect with the an already paired device when it comes within range.
Note: The Bullfrog BF400 system does not support Bluetooth hands-free phone communication.
Kicker Connect App: The Kicker Connect App (for Apple iOS 8.0+ & Android OS 4.3+) lets you select from 5 EQ presets (Kicker / Outdoor / Voice / Treble / Flat), create & select FM presets, control volume, and check battery level right from your compatible smartphone or tablet.
DoubleKick Connect: Using the Kicker Connect App, you can join two Bullfrog BF400 speakers together wirelessly for twice as much sound. This feature is called "DoubleKick Connect". The wireless range between speakers is 30'.
FM Tuner: The Kicker Bullfrog BF400 is equipped with a built-in FM tuner (there is no AM tuner). You can save and select FM presets on the Kicker Connect App for Apple iOS and Android. An external FM wire antenna is included that is terminated by a male 3.5mm connector which plugs into the 3.5mm antenna port on the side of the speaker.
Aux Input: The Kicker Bullfrog BF400 features a side-panel 3.5mm Aux input for connection of practically any portable audio source with an analog output or headphone jack.
USB Charging Port: A side-panel USB (type-A) charging port will charge your connected smartphone, tablet, or portable digital audio player. The USB port is rated at 5V/2.1A.
Top-Panel Controls: The top-panel push-button controls consist of Power On/Off, Play/Pause, Previous/Next Track, Source (Bluetooth/FM/Aux), Pair, and Volume Up/Down.
AC or Battery Power: The Kicker Bullfrog BF400 can be powered by AC or its built-in battery. The Bullfrog BF400 comes with an external AC power adapter that is used to supply power to the speaker and charge the built-in battery. The rechargeable lithium-ion battery (11.1V/3350mAh) provides up to 20 hours of music playback. It takes 2.5 hours to full recharge the battery. 5 top-panel LEDs indicate battery power level.
