SoundStream Motorcycle Radios
No Headset Bypass Required

About SoundStream
Soundstream has been building amplifiers, subwoofers, speakers and multimedia head units since 1976. The company describes itself as a leader in mobile audio engineering and performance over that span, and says its work has earned over 90 industry awards. Its catalogue still covers the ground it came up on — multi-channel amplifiers, component speakers, signal processors and marine audio — alongside the newer video and multimedia side of the business.
Soundstream describes Reserve as a premium line of vehicle audio products originally created for select authorized dealers, and the Harley-Davidson touring head units sit in it. The idea running through them is the same: a head unit that drops into the factory location on a specific bike rather than a universal chassis you have to fabricate around. Reserve units use OEM mounting hardware, the bike's original AM/FM antenna and OEM USB where it exists, so there are no brackets, trim rings or antenna adapters to source separately. Factory handlebar controls are retained.
What these units are known for is the amount of amplification and tuning built into the head unit itself. Most of the range carries a 200-watt four-channel amplifier that is 2-ohm stable, multi-band digital equalisation with crossovers, and 5-volt RCA outputs if you later want to run external amps. Faceplates are rated IPx5. Wireless Apple CarPlay and wireless Android Auto are standard across the motorcycle line.
Frequently asked questions
Who is SoundStream and why choose them for my Harley?
SoundStream has built mobile audio since 1976 and carries 90+ industry awards for car and powersports audio — not a newcomer badge-engineering a generic head unit. Its Harley-Davidson “Reserve” line is built plug-n-play for specific bikes, dropping into the factory dash location and using OEM hardware, so you get a proven audio brand without an improvised install.
Which SoundStream unit fits my Harley?
Fitment is split by touring generation and screen size: 2014–2023 touring bikes take the 8″ V2 or the 7″ WHD14+, while 1998–2013 touring bikes take the 8.3″ SG-V2 or the 7.7″ WHD.9813, with model-specific WHDRG (Road Glide) and WHDSG (Street Glide/Ultra) options for that same era. Run your year and model through the fitment finder to land on the exact page.
I ride a Polaris Slingshot — does SoundStream make anything for that?
Yes — the SS-1824 is SoundStream’s dedicated Reserve unit for the 2018–2024 Polaris Slingshot. It’s a separate platform from the Harley Reserve line, so check its own page for exact model-year coverage before ordering.
Does SoundStream have Apple CarPlay and Android Auto?
Every SoundStream Reserve moto unit ships with native wireless Apple CarPlay and native wireless Android Auto built in — there’s no bypass box and no extra part needed to get phone projection running. Pair your phone once at setup and CarPlay or Android Auto launches on the factory screen from then on.
Is Android Auto wired or wireless on SoundStream units?
Wireless. SoundStream builds wireless Android Auto and wireless CarPlay into every Reserve head unit, so there’s no cable running to your phone and no wired adapter to lose in a saddlebag.
What does HogPlay add on top of a SoundStream Reserve unit?
Since CarPlay and Android Auto are already native, HogPlay’s Piglet layers in Mirror Link plus AirCast/AirPlay screen mirroring, and the Media Box adds streaming apps like Netflix and YouTube along with SD card and USB media playback. Both bolt onto any SoundStream Reserve unit in this lineup — pick one, the other, or both depending on what you want on the screen.
Do I need the Piglet or Media Box to use CarPlay on my SoundStream unit?
No. CarPlay and Android Auto are native to the head unit itself, so you’re covered for phone projection out of the box. The Piglet and Media Box are optional upgrades for screen mirroring and streaming apps — add them only if you want those extra features.
Do SoundStream Reserve units need a bypass to install?
No. These are direct plug-n-play replacements that drop into the factory head unit location using your bike’s OEM wiring, OEM antenna, and OEM USB — no bypass module and no cutting into the factory harness.
More questions (8)
Will a SoundStream unit fit my 2024+ Skyline-platform Harley?
No. 2024+ Skyline touring bikes run a factory A2B digital audio bus with no aftermarket drop-in path, so no SoundStream Reserve unit — or any other aftermarket head unit — fits that platform. Check the fitment finder to confirm which side of that line your model year falls on.
What’s common across a SoundStream install regardless of model?
Every Reserve unit is built around your specific bike’s factory dash opening, so it reuses the OEM mounting hardware, the original AM/FM antenna, and OEM USB, and it keeps your factory handlebar controls working exactly as they do today. That means the swap is closer to a stereo upgrade than a rewire job.
Will I lose my handlebar audio controls with a SoundStream unit?
No — factory handlebar controls are retained on every SoundStream Reserve unit. Volume, source, and menu controls on your grip keep working the same way they did with the stock radio.
How does SoundStream compare to other aftermarket Harley radio brands?
SoundStream’s edge is decades of dedicated mobile-audio engineering (since 1976, 90+ awards) paired with native wireless CarPlay and Android Auto on every Harley model in the line — not every aftermarket brand covers both platforms natively. If you’re cross-shopping, compare screen size, your bike’s year range, and whether the brand needs an add-on box for phone projection; the fitment finder will confirm which SoundStream model matches your bike either way.
Are SoundStream Reserve units weatherproofed for a motorcycle?
Yes — these are purpose-built motorcycle head units, designed to handle the vibration, temperature swings, and weather exposure of a Harley dash, not a car stereo repurposed for a bike.
What if I’m not sure which SoundStream model my bike needs?
Run your bike’s year, make, and model through the fitment finder and it will route you straight to the correct SoundStream page — V2, WHD14+, SG-V2, WHD.9813, WHDRG, WHDSG, or SS-1824. Each model page then covers the exact screen size, harness, and install detail for that bike.
Can I stream Netflix or YouTube on a SoundStream unit while riding?
Native streaming apps aren’t built into the head unit itself — that’s what the HogPlay Media Box adds, along with SD card and USB media playback, on top of any SoundStream Reserve unit.
What if my exact touring model isn’t obviously a Road Glide or Street Glide?
For 1998–2013 touring bikes outside the dedicated WHDRG (Road Glide) and WHDSG (Street Glide/Ultra) fits, the general-fit WHD.9813 covers the broader touring range. The fitment finder will confirm the exact match for your year and model before you order.
