About the Boss Audio PHANTOM 800

(Heck)-raising sound for your motorcycle or ATV

Ever jump out of your seat a little bit when a skeletal hand burst out of the ground towards the end of a horror flick? Of course you have. Ever thought, “Hey, wouldn't it be cool if that hand was holding a 3” powered speaker with built-in Bluetooth connectivity?” Sure, who hasn't? Okay, maybe it's just us, but either way, these Boss speakers are totally wicked – in the good way.

Ever jump out of your seat a little bit when a skeletal hand burst out of the ground towards the end of a horror flick? Of course you have.

Okay, maybe it's just us, but either way, these Boss speakers are totally wicked – in the good way.

Spellbinding performance

These speakers are made for outdoor adventuring. You can use Bluetooth® to stream Spotify and Pandora, or plug an MP3 player into the aux jack and enjoy your digital music library. It'll all sound good through these rugged, all-weather 3" Boss speakers. The Class D amp will produce plenty of punch, and the in-line controls will allow you to control the volume and other necessary functions.

The package includes two 3" full-range speakers and all the hardware you need for installation, including mounting brackets that can fit 1" to 1-1/2" handlebars.

Installation Note: If an ignition-power source (at least 5A) is not available, you'll need an SPDT relay (sold separately) for connecting power to the battery.

Product Research


Speakers: The Boss Phantom 800 handlebar speaker system features two 3" full-range, weatherproof speakers with integrated custom-tooled skeleton-hand mounts. Both speakers are powered from a built-in Class-D amplifier mounted in the left speaker. Included speaker wires pass right channel signals to the right handlebar speaker.

Sources: The Phantom 800 speaker system features two playback source options:

  • Aux Input: A 3.5mm Aux input jack is included for connecting to the audio output of a portable device such as an MP3 player or a smartphone. A protective rubber cap is provided for the 3.5mm jack when not in use.
  • Bluetooth Streaming: Built-in Bluetooth technology lets you stream music, via the A2DP protocol, from a compatible device like a smartphone. This lets you play music stored on the device or stream from music services like Pandora or Spotify. A simple pairing procedure (default passcode: 0000) lets you connect your device for playback. Note: Bluetooth hands-free phone calls are not supported.

Remote Volume Control: Included with the left speaker's wiring is a remote volume control for adjusting the volume for both speakers. The remote volume control is compact enough to mounted or zip-tied within easy reach of the rider.

Mounting: Designed for motorcycles and UTVs, the Phantom 800 speakers feature skeleton-hand handlebar mounts integrated with each speaker. The mounts include pre-installed rubber inserts for mounting to 1" diameter handlebars, but inserts for 1.25" and 1.5" handlebars are also provided. Allen-keys are included for mounting and adjusting the tilt of each speaker.

Wiring: The Phantom 800 speaker system's left speaker includes a 60" wiring harness with power and ground wires that will need to be tied into the vehicle's electrical system. Power should be accessed from a switched source, allowing the system to power on and off with the ignition switch. An inline 5A mini-fuse is provided to protect the speaker system.

Note: If an ignition-power source of at least 5A is not available, an SPDT relay (sold separately) may be required for connecting power to the battery.

How to connect to my electric scooter?

Greetings Gabriel, and thank you for your question. We do offer technical support over the phone for your purchases, just not over the Q and A section of our website. Please call the tech number you received on your shipping confirmation email. Thank you for your business.

Can you wire up 2 sets of these speakers together for a 4 speaker system?
[ Michael  Aug 15, 2021 ]
1 answer
These do not have a way of outputting audio to allow a second set to be used with them
[ Paul  Aug 21, 2021 ]  Staff
How many watts are the speakers?
[ James  Mar 25, 2021 ]
2 answers
They don't indicate wattage in the literature. However there is an inline 5 amp fuse which combined with a 12 volt system should max out at 60 watts. They are really loud but at highway speeds they struggle to be heard. The mounting options and long lengths of wire make setup very customizable. Nice speakers. I think the grill is starting to rust far too quickly but I'll hit it with some black paint.
[ SKIP  Mar 26, 2021 ]
not sure about the watch but they look good and sound good I got to mount it on a 20/20 road King
[ JOHN A  Mar 26, 2021 ]
When I read the first question of can you clearly hear these speakers at highway speeds the fist answer was yes even on his stratoliner at 100mph. The second answer was No without a windshield nope and with a windshield does not make much difference. Who do I believe?
[ Hawaiian Brian  Aug 16, 2020 ]

Hi Brian, thank you for your question! Sound quality is really subjective to the end user. There could be 10 people who love a speaker and it's performance in particular environments and uses, and then there could be 10 more behind those who say that the performance does not meet their needs. We will be more than happy to go over these speakers, as well as look into other options that would suit your needs. Also, keep in mind that we do offer a generous 60-day-from-date-of-purchase return policy. So if you were to try these out, and not like them, we will be happy to set you up with a return or exchange. Please chat with us online or by phone at 1-800-324-9695.
[ Jess  Sep 06, 2020 ]  Staff
I cant! To me they r good just for in around city riding!
[ MICHAEL  Sep 02, 2020 ]
Is this system good enough that you can clearly hear the audio at highway speeds?
[ Jason  Nov 26, 2019 ]
2 answers
Yes even at 100mph on my 1900 stratoliner with Vance Hines pipes
[ Michael Dan  Nov 26, 2019 ]
No Windshield is Nope! With a Windshield means very little.
[ MICHAEL  Nov 26, 2019 ]
From the sound of it in future models I for one refuse to buy anything audio that doesn't have audio outs for growth and more suitable to each person's needs adjustments. I would think you'd want that as well as it opens doors for you to be able to sell more products. While ensuring the sound the individuals purchasing your products are pleased with their experience. It's a win win for everyone involved. Food for thought?

We certainly appreciate your feedback and want to make sure we can provide the products that appeal to our customer's needs. Hopefully in the future we will have a similar product that will be expandable to provide more versatility. Thank you again for your honest feedback!

how many watts ?
[ james  May 26, 2020 ]
1 answer
900 these speakers are the bomb. I tried 3 other set before the phantom. at 80mph on interstate I can heat them great
[ THOMAS  May 26, 2020 ]
So I just hook these up to power and ground and control them via bluetooth on my smart phone?
[ Scott  May 21, 2020 ]
3 answers
I hooked mine up to a toggle switch so it won't drain battery, and yes they work off blue tooth
[ Scott  May 24, 2020 ]
Yes, I hooked the hot wire up to the ignition power so it turns of with the key and the ground wire to the negative on the battery. it does come with a volume control button I mounted on the handle bars but you also use the Bluetooth volume. It's a nice system, enjoy.
[ Garry  May 23, 2020 ]
U have to install a Relay in between the power wire so u can turn the speakers off and on and use them with accessory switch on ur Motorcycle. The speakers itself does not have a power on/off switch it self. Thats why u have to install a relay so u can use the bikes ignition switch to power them on/off. After wired correctly then u can use ur Bluetooth on ur phone or use a mini wired cord from ur cell phone to the speakers. Also mp3 players works also.
[ MICHAEL  May 22, 2020 ]
are the speakers a constant drain on batteries?
[ Jeffrey  Mar 08, 2020 ]
3 answers
I had mine professionally installed. They only draw power when the bike is on.
[ Shawn  Mar 09, 2020 ]
U have to wire to the Auxiliary Power Ignition Switch and use a Relay! Look at Boss Audio Website for wiring instructions and ask a Crutchfield Tech!!
[ MICHAEL  Mar 08, 2020 ]
That depends on how you hook them up. On my HD Fatboy Lo I attached them to the Accessory cable, so it turns on when I switch the bike on, but does not drain the battery when the bike is off. The speakers themselves do not have an on off switch, but that can be added in line if you want to get creative
[ A  Mar 08, 2020 ]
Can u buy a single speaker to replace one?
[ H P fruge  Jul 16, 2019 ]
1 answer
No we don't sell the speakers as individual units. You would need to buy a pair.
[ Cosmo  Jul 21, 2019 ]  Staff
Can 2 pairs of these speakers be paired to work together to enable a 4 speaker system?
[ Jonathan  Jun 18, 2019 ]
2 answers
I only have a single pair, if the blue tooth will connect to both, or maybe wire them together it might, one thing these speakers are big, I have a 2017 Harley low rider and I don't have room for another set.
[ Scott  Jun 19, 2019 ]
Not for sure but im thinking No! Contact Boss Audio to be certain!
[ MICHAEL  Jun 18, 2019 ]
