Factory Audio Systems: What Avalon Offers
Before you start planning upgrades, it’s worth understanding what your Avalon boat might already have. The company has been stepping up its audio game in recent years.
The Aura QL: Portable Audio Innovation
The 2026 Aura QL represents a fresh approach to pontoon boat audio . Instead of permanently mounted speakers, this model comes equipped with JBL Flip 6 portable speakers that can be moved anywhere on the boat—or even taken onto the beach.
Here’s what makes this setup special:
- Fully Portable: The speakers aren’t fixed in place. You can position them for optimal sound wherever you’re sitting.
- Stereo Pairing: Through the JBL app, you can synchronize multiple speakers for true stereo sound that really rocks .
- Beach-Ready: When you pull up to a sandbar or beach, grab the speakers and take your music with you.
- Backed by Quality: This system comes from Avalon’s partnership with JBL, a name synonymous with quality audio.
Would a portable speaker setup work better for your boating style than a permanently installed system?
The LSZ Series: High-Performance Fusion Systems
For boaters who want serious sound built right in, the Avalon 2385 LSZ Rear Fish model delivers. This high-end tri-toon comes factory-equipped with a High Performance Fusion sound system as part of its upgrade package .
The LSZ’s audio features include:
- Fusion marine-grade stereo: Built specifically for marine environments
- USB audio inputs and charging: Keep devices powered while streaming
- Integration with GPS: The Garmin 72CV GPS pairs with the audio system for seamless control
- Premium speaker placement: Strategically positioned for optimal sound across the spacious deck
Have you explored all the features of your factory Fusion system? Many boaters don’t realize how much control they have over sound zones and EQ settings.
The Evolution of Marine Audio
Marine audio has transformed dramatically over the past few decades. Here’s how we got to today’s sophisticated systems:
// No external library needed for this visual timeline1980s-1990s
Basic AM/FM cassette decks with “weatherproof” covers. Speakers were car speakers with plastic covers—they didn’t last long.
2000s
CD players arrived, and manufacturers began using UV-resistant materials. The first true marine-rated speakers appeared.
2010s
Bluetooth streaming revolutionized boat audio. No more CDs! Fusion and JL Audio became the gold standards for marine sound.
2020s
Portable speakers integrated into boat design. Wireless multi-room audio, app control, and high-resolution streaming define the modern experience.
Today
Systems like the Fusion Apollo RA800 offer Wi-Fi streaming, AirPlay compatibility, and 50% more amplifier power than previous generations .
Choosing the Right Marine Audio Components
Whether you’re upgrading an older boat or adding features to a newer one, here’s what to look for in each component.
Marine Head Units: The Brain of Your System
The head unit controls everything. Modern marine receivers offer features that car stereos can’t match.
The Fusion Apollo RA800
Garmin’s Fusion brand sets the standard for marine audio. The new Apollo RA800 represents the current state of the art :
- 50% more amplifier power than its predecessor (the RA770)
- High-resolution lossless audio through Wi-Fi and AirPlay
- 4.3-inch LCD display that remains readable in direct sunlight
- 8x faster processor for instant response
- Built-in DAB tuner for digital radio
- Stereo grouping capability to connect multiple Apollo stereos across different listening zones
With an MSRP of $999.99, this is a premium upgrade—but for serious audiophiles, it delivers unmatched performance.
The Clarion CMM-20 Marine Receiver
For boaters who want reliable performance without the premium price tag, Clarion offers a compelling alternative :
- IP66 weatherproof rating—built to exceed industry standards for salt-fog and UV exposure
- 100 watts of power (25W RMS x 4 channels)
- Bluetooth audio streaming with built-in NOAA weather radio
- Dual-zone capability for separate volume control in different areas
- USB input with 1A charging for devices
- Large, backlit buttons that are easy to use while underway
The CMM-20 proves you don’t need to spend a fortune to get solid marine audio performance.
Marine Speakers: Built for the Elements
Speakers take the biggest beating from sun, spray, and temperature swings. Here’s what to look for.
Key Features of Marine Speakers
When shopping for speakers for your recreational boat, look for these specifications:
- UV-resistant materials: The cones and surrounds must withstand constant sun exposure
- Waterproof rating: Look for IP-X4 or higher for splash resistance
- Corrosion-proof hardware: Stainless steel or coated components
- Polymer baskets: Resist rust better than metal
- Butyl rubber surrounds: Last longer than foam or paper
Budget-Friendly Options That Deliver
If you’re upgrading on a budget, several options offer solid performance :
| Speaker Model | Size | Power (RMS/Peak) | Key Feature |
|---|---|---|---|
| Pyle PLMR62 | 6.5″ | 100W / 200W | Completely waterproof, Poly Carbon cone |
| Kenwood KFC-1653MRB | 6.5″ | 50W / 150W | Marine-grade design, PEI tweeter |
| Skar Audio SK65M | 6.5″ | 160W / 320W | 2-Way marine full range, butyl surround |
| Pyle PLMR652W | 6.5″ | 300W / 600W | Heavy-duty weather resistant, ABS housing |
| Pyle PLMR24 | 3.5″ | 100W / 200W | 3-way design, LED lighting, fits tight spaces |
The Pyle PLMR652W stands out with its 600-watt peak power—enough to fill a large pontoon deck with clear sound even at high volumes.
Polk Audio: A Popular Upgrade Choice
One Avalon owner who upgraded their 2015 LSZ 225 installed Polk UM651 speakers as a significant improvement over the factory sound . Polk’s marine series is known for:
- Excellent sound quality
- Durable construction
- Good value for the performance
Amplifiers: Power When You Need It
Factory head units provide basic power, but if you want your music to be heard clearly at speed or across a crowded deck, an amplifier is essential.
Why Add an Amplifier?
A forum member with a 2015 Avalon LSZ 225 discovered what many boaters learn: four upgraded speakers sound good, but adding an amplifier takes things to another level . Here’s what an amp does:
- Cleaner sound at higher volumes without distortion
- Better bass response from your speakers
- Ability to add a subwoofer (with a 5-channel amp)
- Consistent performance even when the engine is running
What to Consider
- 4-channel amplifier: Powers your main speakers
- 5-channel amplifier: Adds a subwoofer channel
- Marine-rated construction: Essential for longevity
- Installation location: Choose a dry, ventilated spot
Would a dedicated subwoofer complete your boat’s sound system? Many boaters say it’s the missing piece that transforms the listening experience.
Portable Speakers: The New Frontier
The Aura QL’s portable JBL speakers represent a growing trend . The benefits of portable audio on a pontoon include:
- Flexibility: Move speakers to where people are sitting
- Beach compatibility: Take your music ashore
- Easy replacement: If a speaker fails, you’re not rewiring the boat
- No complex installation: Just charge and play
If you’re buying a new Avalon, the Aura QL’s portable speaker system is worth serious consideration—especially if you enjoy beach days and sandbar gatherings.
Installation and Electrical Considerations
Adding audio equipment to your boat requires attention to your electrical system.
The Importance of a Second Battery
This cannot be overstated: if you’re upgrading your audio system, install a second battery.
Avalon’s own technical documentation notes that some stereo models have active components that may drain the battery even when the stereo switch is off . A dual-battery setup with a switch lets you:
- Run your stereo off one battery while keeping the other reserved for starting
- Avoid being stranded with a dead battery after a day of music
- Run your system longer without worry
Did you know that a modern amplifier can draw 20-30 amps at high volume? That’s enough to drain a starting battery in a few hours.
Wiring and Fusing
Avalon’s technical information emphasizes proper electrical practices :
- DO NOT exceed fuse ratings—each circuit is protected for a reason
- Install additional equipment on separate fused circuits directly to the battery
- Use marine-grade wire—automotive wire won’t hold up
- Let a professional handle complex installations—errors can cause fires or damage expensive components
Your dealer or a qualified marine electronics installer is worth the investment when adding amplifiers and subwoofers.
The Stereo Switch
Many Avalon boats come with a music on/off dash switch . Here’s the important detail:
- The switch must be ON for the stereo to operate
- When you’re done for the day, turn the music switch OFF
- Some stereo models drain power even when the stereo itself is off—this switch prevents that
Have you been leaving your music switch on? If your battery seems to drain mysteriously, this could be why.

Frequently Asked Questions About Avalon Boat Marine Audio
What audio system comes standard on new Avalon boats?
Standard systems vary by model. The 2026 Aura QL features portable JBL Flip 6 speakers, while premium models like the LSZ series offer Fusion marine audio systems.
Can I upgrade the stereo on my older Avalon boat?
Yes. Many Avalon owners successfully upgrade their systems. A 2015 LSZ 225 owner reported upgrading to Polk speakers with excellent results.
Do I need a second battery for a powerful stereo?
Yes, it’s highly recommended. High-output amplifiers can drain a starting battery quickly. A dedicated audio battery with a selector switch prevents being stranded.

The JBL Flip 6 speakers are fully removable. You can position them anywhere on the boat for optimal sound, and they synchronize through the JBL app for stereo playback. You can also take them onto the beach.
What’s the best marine audio brand for pontoons?
Fusion (by Garmin) and JL Audio are widely considered the premium choices. Polk Audio offers excellent mid-range options. For budget-conscious buyers, brands like Kenwood, Skar, and Pyle provide solid entry-level marine speakers.
Can I add a subwoofer to my Avalon’s existing system?
Yes, but you’ll need an amplifier with a subwoofer channel (a 5-channel amp) or a dedicated subwoofer amplifier. Installation is more complex and may require professional help.
Making Your Sound System Last
Your luxury pontoon boat deserves a sound system that lasts. Here’s how to protect your investment:
- Rinse with fresh water after saltwater exposure
- Use protective covers when the boat is stored
- Check connections periodically for corrosion
- Remove portable speakers when not in use
- Turn off the stereo switch when leaving the boat
“The difference between a good marine audio system and a great one often comes down to installation quality and proper power management. A second battery and quality wiring make as much difference as the components themselves.”
