ST900 Speaker System
If everything is connected and powering on but you have no sound, please check that the 3.5mm (headphone jack) to RCA cable is connected properly. The RCA end should connect to the input side of the amplifier and the 3.5mm (headphone jack) side should connect to the female 3.5mm (heapdhone jack) plug on the MTX Bluetooth handlebar controller.
All Speaker Systems
Most of the time when there is no sound (or the system is not turning on) it is due to the remote/switched wire connection (Orange wire on ST200 Classic, Blue/White wire on the ST600 Cruiser and Solid Blue wire on the ST900 Platinum). To confirm the system works you can connect this remote/switched wire directly to battery positive and the system should turn on. If so, then check that your switched power source connection is connected properly per the instruction manual (this is a source that comes on and off with the bike).
Also check that the Positive (+) and Negative (-) wires are securely connected to the battery. These 2 wires and the above mentioned remote/switched wire must all be properly connected for the system to work, even if the amplifier appears to turn on.
Check that the wires are not cut, melted or have any bare wire between the amp and speakers, battery or switched wire.
Check that the fuse is still good, even if the amp light(s) still turn on.
Lower the gain adjustments on the amplifier and adjust the EQ on your audio or mobile device (if equipped)
Connect the ground wire directly to the battery to avoid any interference. Be sure to run the wires away from spark plugs and ignition, or anything else that could cause interference.
Check that the positive round (+) and negative squared (-) speaker wires are connected to the correct positive (+) and negative (-) connection on the amp. If these are not connected properly, the speaker will be "out of phase," and result in audio oddities. Although this is not dangerous to a speaker or amplifier, proper power delivery and speaker response is not possible with reversed speaker wires.
Check where the wire goes in to the speaker housing stem that there is no exposed wire causing a short. If so, please contact us for warranty repair.
If you have a whining noise through the speakers when revving the engine, please contact us to request a free noise filter.
Check that the 3.5mm to RCA cable does not have a short causing static or other interferance. To check it, wiggle it around where it is connected to the amplifier and audio device/Bluetooth controller. If there is feedback or static when moving the cable, request a replacement from us under warranty.
If you are not using Bluetooth, be sure the headphone jack is completely plugged in to the audio device. Many phone cases can prevent a complete, solid connection
If you are downloading MP3 files to your audio device (instead of streaming), check that your music (MP3) files are of good quality (128+) and recorded at the proper volume
Check that the gain (or fader) adjustment on the amp is turned up (but not too much to cause distortion).
Check that the volume on your audio or mobile device is turned up and the EQ is set properly.
Check that the positive (+) and negative (-) speaker wires are connected to the correct positive (+) and negative (-) connection on the amp. If these are not connected properly, the speaker will be "out of phase," and result in audio oddities. Although this is not dangerous to a speaker or amplifier, proper power delivery and speaker response is not possible with reversed speaker wires.
Streaming services such as Pandora and Spotify can produce a lower output and clarity if there is poor signal strength. In these cases, try using your onboard (MP3) music player.
After re-checking all wire connections, if you only have output from one speaker, then try swapping the left and right channels on the amp. If the same speaker still does not work, then it is a bad speaker. If the other speaker stops working, then it is a bad channel on the amp. Contact us to submit a warranty claim for the appropriate part.
ST900 Platinum System / PBR Rockford Amplifier
Does the light go red on your amp and music stop playing? This is typically due to an issue with Ohms, heat or wiring. First, make sure you are using Steel Horse Audio speakers, or if they are a different brand, be sure they are at least 4ohm stable..... 2ohm or 8ohm speakers will cause damage to the amp as well as result in clipping and overheating.
All Other Systems
Be sure to also check that the black plug that connects to the amp with the ground and positive has a good solid connection and all the wires are screwed in securely.
If your amplifier is getting extremely hot but still playing fine, then this is typically within normal operation. The amplifiers are designed to dissipate heat to the outer shell and can get upwards of 150 degrees on the outer shell (still within safe operating temperature). If however the amp is extremely hot with other issues (poor sound quality, strange noises, no output, shutting off, etc), then it could be overheating and/or shorting out and these steps should help:
Check that the amp has some breathing room. It should not be wrapped in any material and should have some space around it.
Check that there are no exposed or kinked wires that could be causing a short. Follow each wire from the amplifier to the speakers, battery, and switched source wire to ensure they are not exposed or touching the frame or other metal. An exposed wire on any part of the frame or metal could cause an overheating and/or shorting out issue with your amplifier.
Double check all your connections. One simple pinched wire or crushed fuse can cause overheating or other issues. Check your ground and power wires. Something as small as a loose ground connection can cause numerous issues.
Another option is to completely remove the system from the bike and bench test it. If it only works when off the bike, then there is most likely an internal exposed wire and you should submit a warranty claim.
This happens if you do not connect the Bluetooth controller correctly. The controller must be wired to the battery with the red (+) and black (-) wires, then connect the blue wire to the blue wire from amplifier. Then connect the 3.5mm to RCA cable from the amplifier to the Bluetooth controller. Next, pair your audio device with the Bluetooth controller. (NOTE: When there is no source connected or music playing for more than 5 minutes, it will shut off the system due to the built in fail-safe. This helps prevent battery drain but if not connected properly, will cause the system to shut off every 5 minutes.)
