Can You Install 6×9 Speakers in Factory Harley 6.5 Lids? The Expert Answer

Yes, you can install 6×9 speakers in factory Harley 6.5 lids (or 5×7 lids) by using a specialized lid conversion adapter kit. While the factory openings are too small for a 6×9 frame, these aftermarket kits provide a cutting template and a mounting ring that allows you to “drop in” larger speakers without replacing the entire saddlebag lid.

Upgrading to 6x9s is the most effective way to increase mid-bass response and overall volume on a touring bike. In my years of tuning Harley-Davidson audio systems, I’ve found that a well-installed 6×9 in a factory lid often outperforms expensive CVO factory upgrades because you can choose higher-quality, high-sensitivity drivers like those from Hertz or Cicada Audio.

TL;DR: Quick Upgrade Guide

• Feasibility: 100% possible with a conversion kit (e.g., Precision Power or Rockford Fosgate).
• Difficulty: Moderate (requires cutting your factory plastic).
• Tools Needed: Jigsaw or Dremel, Phillips screwdriver, T25/T27 Torx, and a drill.
• Best Results: Requires an external amplifier; factory head units lack the power to drive 6x9s effectively.
• Key Benefit: Retains your factory paint match while gaining 40% more cone surface area.

Why You Should Install 6×9 Speakers in Factory Harley 6.5 Lids

When we look at the physics of motorcycle audio, “surface area is king.” A standard 6.5-inch or 5×7-inch factory speaker simply cannot move enough air to produce audible bass at highway speeds. By choosing to install 6×9 speakers in factory Harley 6.5 lids, you are increasing the cone surface area significantly.

The Advantages of 6×9 Conversion

1. Cost Efficiency: A conversion kit typically costs $150–$300, whereas new color-matched lids can cost $600–$1,000.
2. Sound Stage: 6x9s provide a much fuller sound that fills the “void” behind the rider.
3. Durability: Most modern conversion kits use high-density ABS plastic that is often stronger than the original lid material once reinforced.
4. Aesthetics: High-quality kits come with premium metal grilles that give the bike a custom, “blacked-out” or “chrome” look.

Essential Tools and Parts for the Installation

Before you start cutting into your expensive paint, you need the right gear. Based on my experience in the shop, using a cheap kit is the fastest way to ruin a saddlebag. Stick to reputable brands like Precision Power (PPI), Rockford Fosgate, or V-Twin Audio.

Required Equipment List

• 6×9 Conversion Kit: Must include a cutting template and weather-tight gaskets.
• 6×9 Speakers: Look for marine-grade or IP-rated speakers.
• Rotary Tool (Dremel): Use a high-speed multipurpose cutting bit.
• Blue Painter’s Tape: Essential for protecting your paint from scratches during the cutting process.
• Weatherproof Silicone: To ensure a 100% seal against rain.
• Wire Loom: To protect the speaker wires inside the saddlebag.

Step-by-Step: How to Install 6×9 Speakers in Factory Harley 6.5 Lids

Installing these speakers requires patience. If you rush the “cut,” you can’t go back. Follow this proven process we use for professional bagger builds.

Preparation and Protection

Start by removing your saddlebags and placing them on a soft work surface (like a moving blanket). Remove the lids from the bags by unscrewing the hinges (usually T25 or T27 Torx).

Pro Tip: Cover the entire top of the lid with Blue Painter’s Tape. This prevents the base plate of your saw or Dremel from scuffing the clear coat.

Marking the Template

Most kits, especially those from Rockford Fosgate, provide a physical template. Align this template exactly as specified. Usually, you will align it with the “inner” edge of the lid toward the motorcycle. Trace the cutout line clearly with a permanent marker over your painter’s tape.

The “Point of No Return”: Cutting the Lid

This is where most DIYers get nervous. Use a drill to create a “pilot hole” inside the area to be removed. Insert your Dremel or jigsaw blade.

• Speed Matters: Keep the RPMs high but move slowly to avoid melting the plastic.


• Check Fit: Cut slightly inside your line first, then sand outward until the adapter ring fits snugly.

Mounting the Adapter Ring

Apply a thin bead of weatherproof silicone around the flange of the adapter ring. Place the ring into the hole and secure it using the provided hardware.
Expert Insight: Do not over-tighten the screws. The ABS plastic can crack if you use an impact driver. Use a hand screwdriver to ensure a firm, even seal.

Wiring the Speakers

Run your speaker wire from the lid, down the hinge side, and into the bag. Use Adhesive Cable Tie Mounts to keep the wire flush against the interior of the bag. This prevents your gear (helmets, jackets) from snagging the wires.

Use a Quick-Disconnect Harness between the bag and the bike. This allows you to remove the saddlebags for maintenance without cutting wires.

Best 6×9 Speakers for Factory Harley Lids

Not all 6x9s are created equal. Because these speakers face upwards, they are exposed to sun and rain. You must use marine-certified equipment.

My Top 3 Recommendations

1. Hertz SX 690 Neo: These are incredibly loud and designed specifically for “open-air” environments. They feature a weather-resistant cone and a powerful neodymium magnet that is light enough to not stress the lid hinges.
2. Rockford Fosgate TMS69: These are designed to fit perfectly with the Rockford conversion kit. They are IP65 rated, meaning they can handle a pressure washer (though I wouldn’t recommend testing that).
3. Diamond Audio MP694: Known for “vocal clarity.” If you struggle to hear lyrics over your exhaust, these are the solution.

Managing Expectations: Power and Tuning

One mistake I see constantly: someone will install 6×9 speakers in factory Harley 6.5 lids and then plug them directly into the factory radio.

The result? It sounds worse than stock.

Factory Harley head units (GTS or GT) put out very little power. To make 6x9s move, you need an aftermarket amplifier (at least 100W-150W RMS per channel). Additionally, 2014+ Harleys have a heavy “EQ Curve” from the factory that boosts bass at low volumes and cuts it at high volumes. You will likely need a TechnoResearch or Diag4Bike flash to flatten the radio’s output, or a DSP (Digital Signal Processor) to tune the sound.

Frequently Asked Questions

Can you install 6×9 speakers in factory Harley 6.5 lids without a kit?

No. A 6×9 speaker is physically larger and a different shape than a 6.5-inch round or 5×7-inch oval opening. Without a conversion kit/adapter ring, there is no surface for the speaker to bolt into, and it will not seal against the elements.

Will 6×9 speakers make my saddlebags leak?

If installed correctly with a high-quality kit and marine-grade silicone, your bags will remain 100% waterproof. Most kits use a “gutter” system or a raised lip to ensure water runs off the lid rather than into the bag.

Do I need to upgrade my battery for 6×9 speakers?

You don’t need a new battery for the speakers themselves, but you might need one for the amplifier required to run them. If you are running more than 500 Watts of total power, I recommend upgrading to an AGM battery with higher Cold Cranking Amps (CCA).

Does this modification void my Harley-Davidson warranty?

It will likely void the warranty on the saddlebag lids and the audio system. It will NOT void the warranty on your engine, transmission, or frame. Always check with your local dealer, as some are more “audio-friendly” than others.
