Can You Hear Saddle Bag Speakers While Riding? The Real-World Answer
Can you hear saddle bag speakers while riding? Yes, you can clearly hear saddle bag speakers at highway speeds, provided you use 6×9-inch speakers powered by an external amplifier delivering at least 100W to 150W RMS per channel. Without a dedicated high-output amplifier and proper lid placement, rear speakers often become “lost” behind the wind noise and exhaust note once you exceed 45 MPH.
π Quick Takeaways: Hearing Your Bagger Audio at Speed
If you are looking for the “Short Version” of how to ensure your audio cuts through the wind, here are the essential requirements:
- Speaker Size Matters: 6×9-inch speakers are the industry standard for saddle bag lids because they offer more surface area to move air.
- Power is Non-Negotiable: You cannot run these off a factory head unit; you need an amplifier with high RMS (Root Mean Square) ratings.
- Orientation: Speakers mounted in the lids (facing the rider) are significantly more audible than speakers mounted inside the bags or facing outward.
- The “Sound Stage”: Rear speakers provide the “fill” that prevents your front fairing speakers from sounding “thin” at high speeds.
- Wind Protection: A taller windshield or a full fairing drastically reduces the “noise floor,” making it easier to hear your rear audio.
The Physics of Motorcycle Audio: Why Volume Isn’t Enough
To understand why people ask “can you hear saddle bag speakers while riding,” we have to look at the “Three Enemies of Audio”: Wind, Exhaust, and Distance.
When you are parked, almost any speaker sounds great. However, as your speed increases, the ambient noise floor rises exponentially. At 70 MPH, the wind noise inside a typical full-face helmet can reach 90 to 100 decibels (dB).
The Inverse Square Law
In physics, the Inverse Square Law states that sound intensity decreases significantly as you move away from the source. Since saddle bag speakers are located behind your seating position and lower than your ears, they have a natural disadvantage compared to fairing speakers.
To overcome this, we focus on Sound Pressure Level (SPL). We aren’t just looking for “loud”; we are looking for “projection.” This is why pro-audio style speakers (high-efficiency drivers) are becoming the gold standard for touring bikes like the Harley-Davidson Street Glide or Road Glide.
| Feature | Impact on Audibility | Recommendation |
|---|---|---|
| Speaker Size | High (determines air displacement) | Use 6×9″ over 5×7″ or 6.5″ |
| Amplifier RMS | Critical (prevents distortion at max volume) | 150W+ RMS per speaker |
| Exhaust Volume | High (creates frequency interference) | Use a DSP to boost mids/highs |
| Helmet Type | Moderate (affects ear perception) | Use earplugs (ironically helps clarity) |
| Lid Angle | Moderate (aims the sound) | Use angled spacers if possible |
Choosing the Right Hardware: How to Hear Your Music Clearly
If you want to ensure you can hear saddle bag speakers while riding, you cannot settle for entry-level automotive gear. Car speakers are designed for enclosed, quiet cabins. Motorcycle speakers must be “weather-resistant” and “high-efficiency.”
The 6×9 Advantage
We have tested 5×7-inch factory upgrades and compared them to aftermarket 6×9-inch conversion kits. The difference is night and day. A 6×9 speaker has roughly 25% more surface area than a 5×7. This extra area allows the speaker to produce lower frequencies (mid-bass) that don’t get washed out by the wind as easily.
High-Efficiency “Pro-Audio” Speakers
Brands like Cicada Audio, Diamond Audio, and Rockford Fosgate produce “Pro-Audio” style speakers. These use massive magnets and stiff cones designed to be extremely loud with relatively low distortion. If your goal is highway clarity, look for speakers with a Sensitivity Rating of 93dB or higher.
The Role of the Amplifier
This is where most riders fail. If you underpower a speaker, it will “clip” (distort) when you try to turn it up to hear it over your pipes.
- Minimum Requirement: 100W RMS x 2.
- Expert Recommendation: 200W RMS x 2.
- Why? Having “Headroom” means the amplifier isn’t working at 100% capacity, which keeps the signal clean and the vocals crisp.
Step-by-Step Guide: Installing Saddle Bag Speakers for Maximum Output
Installing speakers in your bags requires more than just a screwdriver. To ensure you can hear saddle bag speakers while riding, follow this professional installation workflow we use in our shop.
Step 1: Selecting Your Lid Strategy
You have two choices: Cut your existing lids using a template kit or buy pre-molded speaker lids.
- Pro Tip: Pre-molded lids (like those from Advanblack or HogTuning) are often sturdier and prevent the “vibration rattle” that can ruin sound quality at high speeds.
Step 2: Reinforcing the Bags
Saddle bags are essentially large plastic echo chambers. At high volumes, the plastic walls can flex, causing “cancellation.”
- Apply Sound Deadening Mat (like Dynamat or SoundShield) to the interior walls of the bags.
This tightens the bass and ensures the sound energy is pushed up* toward the rider rather than vibrating the plastic.
Step 3: Proper Wiring Gauge
Don’t use thin 18-gauge wire. For a high-powered bagger system:
- Run 14-gauge or 12-gauge oxygen-free copper (OFC) wire from the amp to the bags.
- Use quick-disconnect plugs (Deutsch connectors) so you can still remove your bags for maintenance.
Step 4: The Gasket Seal
If air leaks out from around the speaker mount, you lose “punch.” Ensure you use a closed-cell foam gasket between the speaker and the lid. This forces all the sound waves out through the grille.
Tuning Your System for the Highway (The Secret Sauce)
Even the most expensive speakers will sound terrible if they aren’t tuned for a “windy environment.” When people ask “can you hear saddle bag speakers while riding,” they are often complaining about “muffled” sound. Tuning solves this.
Use a Digital Signal Processor (DSP)
A DSP (like the Rockford Fosgate DSR1 or Dayton Audio 408) allows you to adjust the “EQ Curve” specifically for motion.
- The “Smile” Curve: Boost the Highs (Treble) and Mids.
- The High-Pass Filter (HPF): Set your HPF to roughly 80Hz or 100Hz. You cannot hear deep sub-bass at 70 MPH, so don’t waste your amplifier’s power trying to produce it. Redirect that energy into the “Vocal” range (1kHz – 4kHz).
Crossover Settings Table
| Frequency Range | Setting | Reason |
|---|---|---|
| Low End (Bass) | 80Hz – 100Hz HPF | Prevents speaker “bottoming out” at high volume. |
| Mid-Range | Boost +3dB at 2kHz | This is where the human voice lives; helps “cut” through wind. |
| High End (Treble) | Boost +2dB at 8kHz | Provides the “shimmer” and clarity for cymbals/strings. |
Real-World Factors: What Else Affects the Sound?
We have performed “Real-World Road Tests” on various setups. Here is what we discovered regarding the environment:
The Exhaust Factor
If you are running “shorty” pipes or wide-open “Drag Pipes,” your exhaust exit is mere inches away from your saddle bag speakers. The low-frequency rumble of the exhaust will physically cancel out the low-mid frequencies of your music.
- Solution: If you want the best audio, stick with 4-inch or 4.5-inch touring mufflers that exit behind the bags.
The Helmet Myth
Many riders think a helmet makes it harder to hear. In our experience, a full-face helmet actually helps. It acts as a physical barrier to the “white noise” of the wind, allowing you to distinguish the music frequencies more easily. High-fidelity earplugs (like EarPeace or Alpine) are even betterβthey filter out wind roar while letting the music “cut” through.
Maintenance: Protecting Your Investment
Because saddle bag speakers face upward, they are vulnerable to the elements. To ensure you can hear saddle bag speakers while riding for years to come, follow these maintenance tips:
- Hydrophobic Grille Cloth: Use a “mesh” that repels water but lets sound through. Frogzskin is the industry leader for this.
- Drain Holes: Ensure your saddle bags have small drain holes at the bottom. If water gets past the lids, you don’t want your speakers sitting in a puddle.
- Check Tightness: Motorcycles vibrate. Check your speaker mounting bolts every 3,000 miles to ensure they haven’t shaken loose.
Frequently Asked Questions (FAQ)
Will saddle bag speakers drain my battery?
Only if the engine is off. While riding, your stator (alternator) provides the power. However, if you are running multiple high-powered amps (over 1000W total), you may need to upgrade to a high-output stator or a lithium-ion battery with a high reserve capacity.
Do I need to cut my lids to hear the speakers?
Yes. Some “internal” bag speakers exist, but they are significantly quieter. For highway speeds, lid-mounted speakers are the only way to ensure the sound waves have a direct path to your ears.
Can I hear saddle bag speakers with a passenger?
This is the “Zero-Click” truth: Your passenger will hear them perfectly, but they will actually block some of the sound from reaching the rider. If you frequently ride “two-up,” you will need even more amplifier power to compensate for the physical obstruction of the passengerβs legs.
What is the best brand for saddle bag speakers?
Based on our bench testing for SPL (Loudness) and Durability, the top three brands are Cicada Audio, Ground Zero, and Rockford Fosgate (Power Series).
