President Walker IV FCC AM/FM CB Radio + DRX-9010 External Speaker + DRX-6560 4-Pin Noise-Cancelling Dynamic Microphone Combo
President Walker IV FCC CB Radio Combo Kit for Truckers — With External Speaker & Noise-Cancelling Mic
What's in this combo: President Walker IV FCC AM/FM CB Radio + DRX-9010 Driver Extreme Premium External Speaker + DRX-6560 4-Pin Noise-Cancelling Dynamic Microphone. Everything you need to get on the CB in your rig, out of the box — with the truck-cab audio upgrades that make the biggest difference.
Who This Combo Is For
This is a purpose-built CB radio kit for professional drivers running semi trucks, pickups, and heavy-duty work vehicles. If you spend hours behind the wheel and need a mobile CB that punches through diesel engine rumble and cab noise while sounding clean on the other end, this is the combo we recommend. Owner-operators running Peterbilt, Kenworth, Freightliner, Volvo, Mack, and International trucks will find the Walker IV FCC drops cleanly into factory truck radio cutouts, while the DRX-9010 wedge speaker and DRX-6560 noise-cancelling mic solve the two biggest audio problems truck cabs create: engine noise going out, and radio traffic getting drowned out coming in.
Why We Picked These Three Products
- The President Walker IV FCC is the newest generation of the legendary Walker line and the direct successor to the President Walker III that became a truck CB standard. AM/FM operation on all 40 channels, President's industry-leading 0.5 µV AM / 0.3 µV FM receiver sensitivity, NOAA weather channels with weather alert, and modern additions like Glow Mode, Noise Reduction Circuit, and a front USB-C charging port.
- The DRX-9010 external speaker mounts on the dash, headliner, or A-pillar where the radio itself won't fit, and it's tuned for voice frequencies (150 Hz–6 kHz) so voice cuts through diesel engine noise, road noise, and HVAC.
- The DRX-6560 noise-cancelling mic blocks the sound of your engine, wind, HVAC, and cab chatter from leaving your mic — so the driver on the other end hears your voice, not your cab.
Buying these three separately, you'd have to verify the mic pinout matches the radio, confirm the speaker jack matches, and gamble on whether the audio profiles complement each other. We've done that work. Everything here plugs in and works.

President Walker IV FCC CB Radio
The President Walker IV FCC is the newest generation of the Walker line and the direct successor to the popular President Walker III. It keeps the classic OEM truck CB form factor that fits cleanly in factory truck cubbies, radio cutouts, and overhead compartments across Peterbilt, Kenworth, Freightliner, Volvo, Mack, and International semi trucks. The Walker IV adds a modern feature set built for today's road: AM/FM operation on all 40 channels so you reach drivers running newer FM CB radios, President's 0.5 µV AM / 0.3 µV FM receiver sensitivity that pulls in faint stations others miss, and NOAA weather channels with weather alert for storm-country and mountain-pass driving.
Key features: 40-channel AM/FM · NOAA weather channels with weather alert · Glow Mode adjustable backlighting · Noise Reduction Circuit (NRC) DSP filter · Dedicated P-Channels (one-touch channel access) · Automatic Squelch Control (ASC) · VOX hands-free operation · Built-in SWR meter · SWR protection · Front USB-C charging port · 0.5 µV AM / 0.3 µV FM receiver sensitivity · Standard 4-pin microphone connector · OEM truck size — fits factory cubbies and overhead compartments.
DRX-9010 Driver Extreme Premium External Speaker
The DRX-9010 is a wedge-shape external CB speaker designed for tight mounting locations in trucks — under the dash, above the visor, or against the A-pillar. It handles 15 watts nominal and is tuned specifically for voice reproduction, not music, so radio traffic comes through clean and intelligible even at highway speeds.
Specifications: Wedge shape · Heavy-duty bracket included · Detachable 10 ft. 20-gauge twisted pair cable · 15W nominal · 6 ohms · 150 Hz–6 kHz linear voice-tuned response · Operating -4°F to +140°F · 3.5mm straight-to-right-angle plug · 5.0″ W × 4.5″ D × 4.75″ H · 2 lbs. 5 oz. Compatible with any CB radio with a 3.5mm external speaker jack.
DRX-6560 Driver Extreme 4-Pin Noise-Cancelling Dynamic Microphone
The DRX-6560 is a dynamic noise-cancelling mic engineered for the noisy environment of a truck cab. An internal diffuser blocks breath pops and wind, and the dynamic element rejects ambient sound (engine, HVAC, road noise) so only your voice transmits. Ergonomically contoured for one-handed thumb-on-key operation and needs no battery — just plug it in.
Specifications: Dynamic noise-cancelling · Chrome-plated grill · 9-foot cord · Extra-long strain relief · Internal diffuser · Standard 4-pin/6-conductor wiring (Pin 1 Ground: Shield & Blue; Pin 2 Audio: White; Pin 3 TX: Red; Pin 4 RX: Black; Yellow unused) · Sensitivity -54 dB ±3 dB · 500 ohms ±30 ohms · Frequency response 55 Hz–7 kHz.
Frequently Asked Questions
What's included in the President Walker IV FCC combo kit?
This combo includes three products: the President Walker IV FCC 40-channel AM/FM CB radio, the DRX-9010 Driver Extreme Premium External Speaker with mounting bracket and 10-foot cable, and the DRX-6560 4-pin noise-cancelling dynamic microphone with 9-foot cord. All three are pre-verified to work together out of the box.
How is the Walker IV different from the Walker III?
The Walker IV keeps the classic Walker sound, layout, and OEM truck form factor drivers know, and adds AM/FM operation on all 40 channels, Glow Mode adjustable backlighting, a Noise Reduction Circuit for voice audio, dedicated P-Channels for one-touch access, SWR protection, Automatic Squelch Control, VOX hands-free operation, a front USB-C charging port, and NOAA weather channels with weather alert. Same fit, more capability.
Is this combo good for truck drivers?
Yes — that's exactly who we built this kit for. The Walker IV FCC fits standard truck radio cutouts in Peterbilt, Kenworth, Freightliner, Volvo, Mack, and International cabs, the DRX-9010 wedge speaker mounts in tight cab locations where the radio itself won't fit, and the DRX-6560 noise-cancelling mic blocks engine, wind, and HVAC noise from your transmitted audio.
What microphone works best with the President Walker IV FCC?
The Walker IV FCC uses a standard 4-pin, 6-conductor microphone connector. The DRX-6560 in this combo is our recommended pairing for truckers because it's a dynamic noise-cancelling design that rejects cab noise. The included stock mic works too — but the DRX-6560 upgrade is where you'll notice the biggest improvement in on-air audio quality.
Is the DRX-9010 external speaker good for a truck cab?
Yes. The DRX-9010 is one of our top external speaker picks for truckers because of its wedge shape (mounts in tight spots), voice-tuned 150 Hz–6 kHz frequency response, and 15-watt handling that stays clean at highway volume. Its -4°F to +140°F operating range handles seasonal cab extremes.
Does the DRX-9010 speaker work with other radios?
Yes. The DRX-9010 uses a standard 3.5mm external speaker jack and works with any CB radio or amateur radio that has an external speaker output.
Is the DRX-6560 microphone compatible with other radios?
Yes. The DRX-6560 uses standard 4-pin, 6-conductor wiring, compatible with most President, Cobra, Galaxy, and other radios using the same pinout. Always verify your radio's pin configuration before use.
Can I buy the radio, speaker, and mic separately?
Yes, each component can be purchased individually at CB Radio Supply. The advantage of the combo is that we've pre-verified compatibility and audio matching — you don't have to research pinouts, jack types, or frequency response curves yourself.
What antenna do I need for this combo?
This kit does not include an antenna. For a truck install with a permanent mount, we recommend the Stryker SR-A10 antenna. For a temporary or magnet-mount install, the Stryker SR-A10MM magnetic mount version is our go-to. For a home base station, a CB vertical or dipole cut for 27 MHz will get you on the air. Want the antenna included? See our Walker IV FCC combo with SR-A10 antenna, DRX-3402 mount, and DRX-1518 coax.
Where to Buy the President Walker IV FCC Combo Kit
At CB Radio Supply, we've been curating CB radio combos for professional drivers and owner-operators for years. Every component in our combo kits is chosen because we've verified it works — not because it fits in the same shipping box. If you're running a truck and need a CB combo that's ready to install right out of the box, this is the setup we recommend. Contact us if you have questions about your specific truck's install layout or antenna requirements.
