I love this thing, I just got it installed yesterday and took it for a test listen today. It's crystal clear and loud at 85mph with it turned only about 75% of the way up. Compared to the last system I had, this thing is amazing.
It took a little over a month to get them due to amps being on back order, but I’m satisfied so far. The directions that come with the system make installation a breeze. Speakers have good sound and are plenty loud and aren’t flat *** music with no bass. They are 4” speakers so they aren’t gonna thump but very satisfied with the sound and size, they look good on my sportster handle bars
Great sounding system even at highway speeds. Relatively easy to install. Only issue I had was finding a spot to mount the amp and and hide the wiring. Ended up buying a handlebar tool bag and putting it in there.
I have 2 on the handle bars and 2 on the engine bars. After adjusting the fader on the amp to put a little more out of the 2 lower or "back", that helped even out the sound and I also got a 4 way RCA to 3.5 audio and plugged straight into my ipod... Dont worry...you'll hear it at speeds
Great product!! I have tried other systems and they could not compare to this one. My bike is loud, and need plenty of volume in order to hear it going down the road at 70mph. This system fits the bill, and looks really great.
Absolutely fantastic sound system. I ride a 2009 HD CVO Fatbob with really loud Vance and Hines aftermarket pipes and the sound from this system is clear and loud! Installed in about an hour, look and sound great. Only negative was it took a month to receive the system.. definitely worth the wait and the money!
Bought it for my wife for Christmas, and finally got it installed on her Heritage Softail MotorTrike. Her pipes are LOUD, and we took a ride today of about 100 miles and speeds of 25 to 65 mph. She loves it!! The controls are easy to use with thick gloves on, and the volume was plenty sufficient.
Is the amp waterproof? On an Indian Scout there is no place to put an amp except hidden under a speed screen
The amp is water-resistant. It can be exposed to some moisture, but it is not waterproof and can not submerged. Most folks will use a small bag to keep the amp hidden and clean looking, such as a windshield bag, fork bag, front down tube or swing arm bag.
Can this be hardwired to a GPS?
You can connect a GPS, Sateliite or any other audio player using the headphone jack, or output jack on the GPS or other unit, or via Bluetooth connection.
Is this compatible with my existing Harley Davidson radio
Yes, you can use the existing motorcycle radio as the source. You would just use an RCA to 3.5mm cable from the radio to the ST400 system.
Easy installation on a Triumph Rocket III Roadster? I can’t seem to find any videos online to hear the sound.
We design the system to be an easy self-install with only a few wiring connections. You can check out our YouTube page for video, but it just doesn't do it justice like in real life.
How is the BASS????
The bass is fantastic for a 4" woofer. You can actually hear it! It won't 'bump' like a 10" or 12" woofer, but you can definately hear the bass for a nice, well rounded sound.
How long are the speaker wires? Can the amp be mounted in a hard saddle bag? What about airflow/overheating?
The speaker wire is 12 feet in length to accomodate any powersports installation. The motorcycle amp is typically mounted in a saddlebag... a fork bag, windshield bag, down tube bag, swing arm bag, etc will also work. The amp is designed to prevent overheating, even when installed in a confined space without airflow.
what volume control app do u suggest, one that automatically lowers volume and raises as the speed increases or decreases.
For Apple, we recommend 'Volume by Velocity' - Available here: https://apps.apple.com/us/app/volume-by-velocity/id1042222781
For Android/Google, we recommend 'Speed of Sound' - Available here: https://play.google.com/store/apps/details?id=net.codechunk.speedofsound&hl=en_US
Will these speakers fit on the handlebars of a 2016 Indian Chief Darkhorse?
Yes, your Darkhorse will have 1-1/4" stock handelbars and the systems include the correct 1-1/4" mounts (as well as spare 1" mounts).
How many amps does the ST400 draw, on average operation
The ST400 amplifier will draw 10 amps of power on average, peaking at 15 amps.
What are the dimensions of the speaker enclosures?
The speaker enclosures / housings measure 4.75" diameter by 3" depth.
Will this fit easily on my 2016 Fatboy handlebars with a detachable batwing fairing?
Yes, these will fit great with a windshield or batwing fairing.  They can be mounted flush with the bars.
Where does the amp get mounted?
The amplifier measures '5-11/16 X '1-3/4 X '3-7/8 inches and is typically mounted in a saddlebag, fork bag, windshield bag, swing arm bag, front down tube bag or side tool compartment.
Is 10 amp draw constant? Is there a USB input? Can switched power source be a toggle switch? What is the measurement of handlebar clamp? Will I-pod touch work with system?
10 Amps is the peak draw. There is a USB port for charging only, but RCA inputs for a wired connection and Bluetooth for wireless connection. Switched power can be a toggle switch or connected to something that comes on and off with the bike (headlight, taillight, etc). The clamps will mount to a 1" or 1-1/4" bar diameter (other sizes also available). An iPod touch or any other audio device with a headphone jack or Bluetooth will work great.
Any way to attach the 2nd set of speakers to the rear of the bike? like on the sissy bar for the passenger?
Yes, the 2nd set can be mounted just about anywhere, from highway bars and luggage racks to sissy bar/backrest or even in place of the rear foot pegs. They are universal and allow for a lot of different mounting options.
Is it possible to add on 2 more speakers to this amp? I will mount the initial set-up on my handlebars and if I want to add 2 extra speakers later, is that possible?
Yes, this is the same amp that is included with the 4-speaker system for easy upgrading to 4-speakers at any time.
