This post shows how to connect the JBL Boombox 2 monster Bluetooth speaker to Alexa smart speakers. Since this pairing happens between the JBL and Alexa devices directly, you need not turn Bluetooth on in the mobile device you’re using to set up this connection.
How to Connect JBL Boombox 2 to Alexa, Step by Step
With your Boombox 2 powered OFF (power lamp is dark), run through this routine to connect it to your Alexa Echo, Show, Studio, and Dot models. We use an iPad Air tablet to set this up.
1. Find the Alexa app on your Mobile Device
We found the app on the iPad Air as shown in the next shot. In this exercise, the app is in a custom folder that we set up called Smart Speakers, and pointed at by the green arrow.

2. Run the Alexa App
The app displays its Home screen as we see in the next screenshot.

3. Tap the More Item to Continue with How to Connect JBL Boombox 2 to Alexa
Find the hamburger item in the lower right corner of the screen. We point at this with the green arrow in the last screenshot.
This brings up the Alexa app’s main menu, as shown in the next screenshot.

4. Tap the Settings Option on the Main Menu
The Settings option is pointed at by the green arrow in the last photo.
This brings up the Settings screen, as shown in the next screenshot.

5. Tap the Device Settings Option
Touching Device Settings brings up the All Devices page, as shown next.

From here, choose which Echo device you wish to pair with your Boombox.
6. Tap the Alexa Device you Wish to Connect
This takes you to the device-specific settings screen for the speaker you chose.
In this demo, we’re pairing from our Thomas’s 2nd Echo Dot 4 speaker to our Boombox 2, and so, its device specific settings screen looks as follows.

7. Tap the Connect a Device Item
Find the Connect a Device option pointed at by the green arrow in the last screenshot.
This brings up the Setup screen, as we show next.

At this point, your Alexa device scans for nearby Bluetooth devices that are in pairing mode. Here, we selected an Echo Dot 4 earlier. So, this speaker will be the one that scans for BT devices.
Note that our Dot speaker found no devices so far. But it will in the next steps, when we turn on the JBL Boombox 2 and put it in pairing mode.
8. Power Up the Boombox 2
Bring your speaker close to your Alexa device to pair, and power up that speaker by pressing and releasing the Power button as we show in the next picture.

9. Place the Boombox 2 into Pairing / Discovery Mode
Put your Bluetooth speaker into pairing mode by pressing and releasing the Pairing button, as illustrated in the next picture.

10. Find the JBL Boombox 2 on the Alexa App SETUP Page
When you put the speaker into discovery mode, it should then appear in the Alexa app, on the Pair Bluetooth Device… page, as we see next.

Note that if your speaker does not show up on this page at this point, then try moving it very close to the Alexa speaker, closing and restarting the Alexa app, and then repeating steps 3 through 7 along with step 9 above. We usually find that this gets the speaker to appear here as it should.
11. Find your JBL Boombox 2 on the Discovered Devices List
See the last screenshot above. Our test speaker is there.
12. Finally, Pair your Alexa with your Boombox 2
Pair to the speaker by tapping its corresponding entry on the Pair Bluetooth Device… screen, we see in the last screenshot above.
Your Alexa speaker then pairs with the JBL Boombox 2.
The app then takes you back to the Thomas’s 2nd Echo Dot 4 screen, which looks something like the following.

Note that our Bluetooth speaker now shows as connected. Also, the Boombox 2 JBL speaker makes the Speaker Paired sound (the three ascending guitar notes).
This speaker is now connected with your Alexa smart speaker. Its Bluetooth light glows solid white to signal that successful pairing is in effect.
13. Done with How to Connect JBL Boombox 2 to Alexa !
We can now ask Alexa to play music or news, and those programs will come out of the Boombox 2. Be sure though, to speak to the Alexa speaker when making requests, and not the BT speaker. Even though the Boombox 2 is now paired with Alexa, the Echo is still the speaker that receives voice commands through its internal far field microphones.
