My wife wanted to be able to change her songs and adjust the sound on her speakers as well as keep her phone charged. I looked all over and eventually found Steel Horse Audio and took a chance. I had the speaker system installed by our mechanic since I wanted all the wires run right and especially wanted to make sure the speakers and system went on and off with the ignition. I bought a small leather studded bag to match her Heritage Softail look an he installed the amplifier between the speakers and the windshield. I then installed a small studded leather bag onto the inner windshield that anables her to put her phone there. A recharging wire runs out of the amplifier into the other bag that allows her to plug her phone in and put it into the bag. The bluetooth controls were mounted on the left handlebar. She absolutely loves the sound and it's first speakers she's had that she says she can hear well at highway speeds. She gets lots of questions and compliments about her stero but most of all, she feels like she has bagger sound with her softtail. A highly recommend the 400Series with the Kenwood 400W amp since it has the usb port for charging the phone. Great product! You will not be sorry.
Sound is amazing, even on the Highway (Speed 130 km/h) you hear the music loud and clear. Installation is easy, but you need basic knowledge in wiring. I highly recommend to think the whole thing through before starting - saves you a lot of time. Customer service is amazing: friendly and helpful! Even send me another kit via express delivery, when the first one needs months for delivery. Therefore if ordering to Europe use UPS or DHL instead of USPS/local post service.
I ordered this system back in Nov. for my secondary bike. Finally got around to doing the install (instructions are spot on) a few weeks back. Took it for a short run that day and wasn't to get out on it till today. I put 200 plus miles on it today. The sound was excellent, the amp didn't give out or overheat (It was 50 degrees and I wasn't anywhere near full volume). Great product and the sound is very impressive. Joe Griffin, Spring Hill, TN
I have 1.5” crash bars on my 2021 Road King. Do you guys sell the clamps to fit that?
We do! We have 7/8", 1", 1-7/8", 1.25" and 1.5" clamp sizes available!
Can it fit on Harley 2010 CVO SOFTAIL?
The ST400 motorcycle speaker system will fit nicely on a 2010 CVO Softail, as well as most other Harley-Davidson models.
Can the amp be mounted in saddle bags without over heating?
Yes, the amplifier is specifically designed to prevent overheating. It is rated for up to 150 degrees and can safely be installed in enclosed spaces, such as saddle bags or other bags.
I have a 2004 Heritage Softail that has a roadtech sirius XM Radio with the 2 speaker boom system. Can I replace that speaker system with this ST 400 and still connect the RoadTech XM Satalite radio?
As long as there is an AUX or RCA output on the RoadTech radio, you will be all set. These systems will work with any bluetooth audio device or any audio device with a headphone/aux jack.
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.
