Your input is very much appreciated. Share it with your friends so they can enjoy it too!
I have a Kenwood stereo with a pair of 160 rms (320 max rms) skar speakers. Will this amp be ok for that or is it too much power for that setup?
This amp will be a nice fit for those speakers. It will provide up to 200 watts RMS at 4ohm, per speaker, when bridged.
What size power and ground do I need for st600 amp or is it included?
The complete ST600 motorcycle speaker system includes the RF wiring kit. For the amp purchased seperately, we recommend the RFK10 wire kit from Rockford Fosgate.
Can this amp be mounted in the fairing of a 2000 H-D Roadglide? What is needed to be mounted there?
This amp can be mounted rigfht on top of the radio in the fairing. We offer special mounts for this purpose.
Will this amp fit under the fairing of a stock 2018 street glide special?
Yes, it is designed to mount right on top of the radio in the fairing.
Interested in the ST600 amp for a '17 H-D Street Glide Special. Is this a plug n' play type set up or do I need a adapter harness?
The amp connects to a power and ground connection and then connected to the speakers. It is a fairly straight forward install with instructions provided. We also offer adapter harnesses to make it easier but these only cover '96 - '13 model years.
What are the recommended saddlebag speakers for the ST600 amp with my original Harley-Davidson bags?
We recommend the Polk Audio DB692 DB+ Series 6x9 speakers for the saddlebag lids. These are waterproof and perform very well with our ST600 motorcycle speaker system.
Will the ST600 Amplifier handle 2ohm and/or 4 ohm speakers?
The ST600 Rockford Fosgate amplifier supports both 2 ohm or 4 ohm speaker configurations.
I have front speakers and back speakers on my bike. I'm interested in the ST600 amplifier .... can the loudness be changed for the front and back .....like for instance have the back speakers louder than the front speakers
Yes, the gain can be adjusted separately for the front and the rear channels... as well as the variable crossover (EQ).
Will my Bluetooth controller that came with the st-400 plug into this amp?
This amp will only work with the MTX handlebar controller (or similar) that is included with the ST600 system.
Can this amp be placed inside of the saddle bag?
Yes, the saddlebag is one of our recommended locations.
What is the recommended gain setting for the ST600 speakers
We like to push our speakers to their full capability, so typically around 9 or 10 with crossover set to HP or AP.
How much is a Bluetooth controller for this amp?
We offer 2 Bluetooth controller options for the Rockford amplifier. They are priced at $39.99 and $99.95 depending on what features you want. You can see them both here: https://www.steelhorseaudio.com/collections/bluetooth
Does this amp come with the wiring hardware or do you have to buy that separately?
All wiring hardware is included standard with the amplifier. This product also includes the wiring kit for power, remote and ground connections.
Can 2 of these amps be used from the same bluetooth device simultaneously ? I would like to run 2 amps from the same bluetooth source that you sell.
Yes, you could use a headphone splitter from the Bluetooth controller and connect to 2 seperate amplifiers.
Is this a 4 channel amp or 2 channel amp?
It is a 4-channel amplifier.
