How to control your home stereo with Alexa or Google Home

You say it, your speakers play it

Imagine calling out song requests as if you had a personal DJ. And your best speakers would magically play whatever song you requested. In my house, voice control started as a novelty, but has become second nature to use – especially for music. It's just so easy to ask Alexa or Google Home to play music.

But here at Crutchfield, convenience is only part of the story. We always ask ourselves: how can we get better sound? In this article, I'll show you how to integrate voice control into an excellent-sounding home music system.

“I've connected my Echo Dot to an Onkyo receiver that's powering a pair of Klipsch bookshelf speakers," said JR, Crutchfield Training Manager. "I also use this big-sounding system for my turntable and a keyboard, but we always default back to the receiver input for the Echo Dot — so we can talk to Alexa anytime.” 

Voice control: the basics

Amazon Echo and Google Home are the two most popular voice-activated speakers out there. They can answer questions, perform tasks, and even control lots of household devices. Just say “Alexa” for the Echo, or “OK, Google,” and their built-in microphones will start listening.

Smart speakers from leading home audio brands

Many of us use powered speakers as our main way to play music these days. Several leading audio brands have debuted smart speakers with built-in voice assistants. 

Sonos, Harman Kardon, and Ultimate Ears are among the brands that offer speakers with Amazon Alexa built in.

JBL, Polk Audio, Sony and others bring you speakers with Google Assistant.

Read our article "Best smart Speakers for 2019" by Benn Grant.

“I use Alexa to play music through my Sonos speakers," said Morgan, Crutchfield A/V Designer and our in-house voice control expert. "I love the new update that allows me to start music in the room I am in without having to say the room name. My kids love Marshmello, the DJ, and I used to have to say, ‘Alexa, play Marshmello in the kitchen.’ Now I can just say, ‘Alexa, play Marshmello.’ "

How to play music with Alexa and Google Home

So how do you play music with these devices? Both Google Home and Amazon Echo are compatible with music services like Spotify® and Pandora®. Use the Amazon Alexa app or Google Home app to choose your music service(s) of choice (it's the same app you use to set up the device).

When you set up you Amazon Echo (or Google Home), you can link the device to compatible music services.

Once you link a music service to your device, then you’re free to ask the speakers to play what you want. For instance, I keep a Google Home speaker in my kitchen. So when I'm doing dishes, it's as simple as saying, “Hey Google, play some Clapton!” And an Eric Clapton playlist will play through the Google Home's built-in speaker.

Upgrade your sound

Both Google Home and Amazon Echo devices have built-in speakers. But our customers are always interested in better sound. Read on to learn how to connect these products to external audio gear.

Two easy ways to connect Amazon Echo to your speakers

There are a couple of ways to get bigger sound from Amazon Echo. It offers wired and wireless connectivity. And it will work with just about any receiver or integrated amp, as well as a wide variety of powered speakers and sound bars. With any connection, all audio — including Alexa's responses — will play through your connected speakers.

Wired connection with Echo Dot

The tiny Amazon Echo Dot has a 3.5mm or minijack output. That means you can connect it to any receiver, integrated amp, or powered speaker with an AUX input. Just use a mini-to-RCA cable, or a mini-to-mini cable

Echo Dot audio output jack

The Amazon Echo Dot has a minijack AUX output for connecting it to a wide variety of external audio equipment.

Wireless connection via Bluetooth

All Amazon Echo devices feature a built-in Bluetooth transmitter. That means you can send audio wirelessly to any Bluetooth-enabled speaker, sound bar, or home theater receiver.

This made for a clean setup when we paired an Echo wirelessly with the powerful KEF LS50 Wireless speakers. I found it more convenient than a wired connection. You can sit in your favorite chair and request songs without having to shout across the room to where your speakers are set up.  

Klipsch bluetooth speakers with Amazon Echo Dot

The Amazon Echo Dot can connect wirelessly via Bluetooth to powered speakers like the KEF LS50.

A/V receivers with basic Alexa compatibility

There are now some home theater receivers with basic Alexa functionality. You’ll find it in receivers that feature certain multi-room audio systems: Yamaha MusicCast, Denon HEOS, and Bluesound. 

At the moment, these receivers only offer basic Alexa voice commands like play, pause, skip, and volume control. But, more features are promised soon. If you’re shopping receivers and have questions about what you can or can’t control by voice, contact us and we’ll break it down for you.

"Hey Google, play Drake in the den"

The Google Home voice assistant uses Wi-Fi to connect to other audio gear. To super size the sound, you'll need gear that has Google's Chromecast audio built in (also known as Google Cast). Fortunately, there are lots of products to choose from.

There are several home theaters with Chromecast built-in. Those are great choices for adding Google Home to your main system. 

There are also sound bars and powered speakers with Chromecast built in. I have the Polk Mag Mini sound bar in my living room, so I tried it out with the Google Home. The setup was straightforward and painless:

I used the Google Home app to set up the voice assistant to play audio wirelessly through my Polk Magnifi Mini sound bar.

Once the Google Home and sound bar were linked, I renamed the sound bar "den" in the app. That's a lot easier than using the full product name when telling Google Home where to send my music.

Then I was ready to listen. When I called out a song title or playlist, the music played through the sound bar. I could also skip tracks, and even control the bar's volume — all by voice. Very cool!

Turn your voice into a universal remote

Voice control in home theater receivers is currently pretty much limited to music playback. As a write this, you can’t switch inputs or control video by voice with only your receiver. But Harmony’s Hub-based remotes work with Google Home and Alexa – and give you more functionality.

Many of our Advisors have a Harmony Hub in their homes. With one remote you control your whole home entertainment system and smart home components like lights, locks, and more. And with a Google Home or Echo device you can control it all, hands-free.

Man holding speech bubble that says "OK Google, I'm home"

“With the help of the Harmony Hub and Google Home, I can just say ‘OK, google, goodbye’ when I leave home and everything that is smart or connected to a smart outlet shuts down," said Marlon, Crutchfield Advisor. "When I get back? ‘OK, google, I’m home.’ Google turns on the living room lights, and automatically turns on the TV.”

Stay tuned...

The beauty of these voice-assistant devices is that they are always learning new skills. As more products incorporate voice control, we’ll keep trying them out. And we’ll keep you updated.

Have questions?

You can call us at 1-888-955-6000, or contact us by email or chat. Our Advisors stay up to date with this stuff — and of course, many use Google Home or Amazon Echo in their own homes.

    it's not "controlling" your stereo if you have to leave it ON 24/7 and in the correct input mode (aux) all the time so that it will simply play your alexa/google audio those few times you want it. stop using deceptive terms, it is simply a voice activated transmitter/receiver relay system. this is of limited practical use, unless you can list some receiver/stereos that can do like a tv with an amazon firestick connected, and automatically wake/turn on and go to the correct input (digital input only presumably), and begin audio play.

    I currently have my echo in the kitchen and my Denon receiver and speakers in the living room. They are connected, but I can only play one at a time. I essentially want to use the echo as an added speaker in the kitchen. Does it have this capability?

    So I'm looking for a how to use Alexa to control the input on my marantz AVR. I've connected it via Bluetooth and can verbally turn my AVR on and off. I've verified my AVR can verbally change inputs with Alexa.. however there are no instructions on how to make Alexa do this ( set up). Can you point me to a video or give me a phone number so I can talk to someone that can walk me through this process..

    Kelly-- since you ordered from Crutchfield, you get lifetime tech support. One of our technicians will reach out to you. We're in Virginia, so expect a 434 or 276 area code.

    In the meantime, here is some info on Alexa commands you can use with Marantz receivers and other HEOS products:

    Whats the best way to get hi resolution sound from a voice control device to a really good audio setup? If you've spent the time and money on a really good hi-fi, you want really clean, hi-res sources for your music into your hi-fi. For example, I stream from an iPad into my hi-fi using a small outboard A/D. I'm concerned the audio jack output of the Echo dot is probably not very good audio source. Is the Bluetooth output of the Echo any better than this? And how can I get bluetooth to a hi-fi that does not have built in bluetooth?

    Hi Matt!

    There are several ways to accomplish this. I've forwarded your email to one of our product Advisors. They'll follow up with you directly to find the best solution for you.

    (Quick answer to your last question, there are several high-quality Bluetooth adapters out there. Here's my article on the subject:

    Hi Greg

    The goal here is to cover a wide range of voice control options...and share some ways our own people use voice control in their home stereo setups. If there is any topic you'd like me to explore further, please let me know and I'll try to get you more information -- either in the article or here in comments.

    Also, if you have any specific questions, you can give one of our Product Advisors a call at 1-888-955-6000.

    Zoe you don't want to use your phono input. Use a tunner or vcr, aux input, and then you may need to bump up your volume on the echo device to make it a little louder thru the amp just don't over drive that input,

    Hi I have plugged in the echo for to my receiver however it is really quiet compared with the CD or radio. Plugging it into the record (phono) it is slightly louder is this ok?

  • Matt

    Would plugging in Alexa to my stereo receiver auxiliary require the receiver to be left on constantly, or require turning on the receiver to play music. Or does Alexa have the capability to turn on the stereo? Also, I have a Chromecast currently connected to the receiver to play Spotify (which disconnects frequently). Between the two methods do you have an opinion on which is the better way to connect?

    Jeff Miller from Crutchfield

    on 1/21/2019

    Hi Matt, If the only connection between the Echo device and your stereo is through Aux input, Alexa won't be able to turn the receiver on and off. There are ways to make that happen -- adding a Harmony Hub to your setup comes to mind -- so I'll forward your question to an Advisor to follow up with you directly.

    I personally use Google Home to control Chromecast devices in my own home. I wrote a little more about that (and Chromecast in general) here:
  • Scott Hodges from Pittsburgh

    Posted on 1/10/2019

    Yes, well....this article doesn't really fit the title. How-to implies there are instructions on how-to make it work. I have several app-enabled stereos and an alexa in every room. It is easy to connect alexa to a stereo via Bluetooth, but much more efficient to be able to control the output volume through the stereo rather than the input volume through Alexa. I would rather tell alexa to turn the volume up on my pioneer VSX than have to open the icontrol app on my phone or dig through the remotes. Some detail on that process would be appreciated.

    Jeff Miller from Crutchfield

    on 1/11/2019

    Thanks, Scott. Point taken. We're working on an update to this article that will address some of those multi-room apps that are compatible with Alexa. In the meantime, if you got any of the gear in your setup from Crutchfield, give our Tech Support team a call -- they should be able to help.
