Don’t know what to get?
BOOM: here’s some expert advice.

If you’ve never purchased speakers for a car, boat, or ATV before, here’s a little heads up: there are TONS of them. And, though they come in every size and shape for every car make and model, a significant percentage are junk – and often not as good as the stock speakers your car came with. The good news: you don’t have to spend a fortune to significantly upgrade your system if you know what to look for, or who to talk to. That’s what our “Best of 2021” list is all about: our experts cherry-picking the best car, boat, and ATV speakers currently on the market, by category – best for sound quality, best for the money, best coaxial, and so on.

1. The Best-Sounding 3-Way Car Component Speakers: 

Focal ES 165 KX3 K2 Power 6-1/2" 3-way Component Speakers


Regular Price: $2,880.00

Save: $580.01 (20%)

If you’re in the market for a killer-sounding 6-1/2” 3-way car component speaker system, you must check out the ES 165 KX3 speakers from car speaker guru, Focal. Included in this kit are a pair of woofers, a pair of midrange speakers, a pair of tweeters, and a pair of external crossovers. Focal also thoughtfully included some different tweeter mounting adapters so you have some options based on your installation configuration. 

The woofers’ and midrange drivers’ cones are made up of a “sandwich” design which sees a strong Kevlar piece sandwiched between a pair of ultra-thin glass fiber pieces. The result is drivers that are not only lightweight but also incredibly strong. A Tuned Mass Damper (TMD) rubber surround helps eliminate distortion for better sound quality at higher volumes. The tweeters in this Focal speaker kit showcase an “M”-shaped inverted dome for better sound, wider dispersion, and higher peak power handling. The crossovers do include some tuning options built into them, so if you’re looking for more control, look no further! 

All in all, it’s an impressively built kit, but more importantly, it sounds divine. The rich sound quality that these speakers deliver will truly transport you to audio bliss!

ES 165 KX3 K2 Power 6-1/2" 3-way Component Speakers

  • Woofer Material: Composite K2 Power "W" Sandwich Cone
  • Tweeter Material: M-shaped Inverted Kevlar Dome Tweeter

2. The Best-Sounding Car Coaxial Speakers: 

Focal EC 165 K 6-1/2" K2 Power 2-Way Coaxial Speakers


Regular Price: $1,000.00

Save: $200.01 (20%)

The Focal EC 165 K 6-1/2” 2-way car coaxial speakers are truly in a class of their own. We’ve been doing this since ’79 and we have yet to hear a better pair of speakers in this category – and we have heard A LOT. Borrowing materials and technologies from their component speaker siblings, these Focal speakers feature a “sandwich” woofer cone design which means that the sturdy and light Kevlar woofer cones are sandwiched between a pair of ultra-thin glass fiber layers for increased strength and longevity. A hardy rubber surround is highlighted by Focal’s Tuned Mass Damper (TMD) technology for stronger resistance to distortion when that volume knob begins to twist strongly to the right. 

The tweeters built into the speakers follow the “M”-shaped inverted dome design for superb sound quality, better peak power handling, and increased sound dispersion. Capable of handling up to 80 watts continuously, you can rest assured that these coaxial speakers can really rock when you get the proper power running them! 

When it comes to the overall sound quality, we were absolutely tickled with their performance. If you’re gunning for the utmost in sound and are in the market for a coaxial speaker pair of this size, just stop looking and get these!

EC 165 K 6-1/2" K2 Power 2-Way Coaxial Speakers

3. The Best Car Component Speakers Under $500: 

Focal ISU 165 Universal Integration 6-1/2" 2-Way Component Speakers


Regular Price: $400.00

Save: $80.01 (20%)

The ISU 165 6-1/2” component car speakers are hands-down one of the best options available if you’re looking to upgrade from a rather dull sound system in your vehicle to a better-sounding experience.

The woofer cones are made using Focal’s polyglass technology, which is the result of adhering micro glass balls to a pulp cone. This allows the woofer cone to have a fair amount of rigidity without weighing much. This improves mid-range and midbass response while limiting distortion potential. Aluminum magnesium inverted dome tweeters deliver smooth high-frequency response and are protected from harmful frequencies by the slim in-line crossover Focal supplies.

The ISU 165 speakers can handle up to 70 watts of continuous power (and up to 140 watts of peak power), but thanks to their 4-ohm impedance and 93dB sensitivity rating, these things will sound wonderful even running off a factory-installed radio. If you add an amplifier to power them into the fold, they will sound even better. With a mounting depth measuring only 1-15/16”, the woofers will fit into almost any location imaginable. Please note that Focal does not include speaker grilles as they expect the ISU 165 speakers to reside behind existing grilles. So what are you waiting for?

ISU 165 Universal Integration 6-1/2" 2-Way Component Speakers

  • Nominal Power Handling: 70 watts
  • Maximum Power Handling: 140 watts
  • Sensitivity: 93dB
  • Frequency Response: 60Hz – 21kHz

4. The Best Car Component Speakers Under $200: 

JL Audio C1-650 6-1/2" C1-Series 2-Way Component Speakers

If you've ever looked at anything car audio-related, you probably saw the name “JL Audio” thrown around and for very good reason: they are one of the leading manufacturers in car audio and have been since their inception in the late 70s. The C1-650 6-1/2” car component speakers from JL have quite the pedigree to uphold, but they do so effortlessly. The mineral-filled, injection-filled polypropylene woofers cones are strong, but lightweight, ensuring dynamic midrange and midbass performance. These woofer cones are attached to the stamped woofer baskets with a durable rubber surround. The high-frequency response it handled via edge-driven aluminum dome tweeters that sound crisp, but not overwhelmingly bright. Inline outboard high-pass filters protect the tweeter from harmful frequencies are small enough to tuck away just about anywhere – simplifying the installation process by quite a bit, too!

Best of all, while the speakers handle up to 50 watts of continuous power, their 91dB sensitivity ensures that they will run well off of factory-installed radio power all the way through aftermarket amplification. You can make a simple audio upgrade by getting the factory speakers out of your ride and putting the JL Audio C1-650 car speakers in their place!

C1-650 6-1/2" C1-Series 2-Way Component Speakers

  • Woofer Material: Polyglass
  • Tweeter Material: Aluminum/Magnesium
  • Impedance: 
  • Sensitivity: 93dB

5. The Best Low-Power Car Coaxial Speakers: 

Kicker 46CSC654 CS-Series 6-1/2" 2-Way Coaxial Speakers


Regular Price: $89.95

Save: $8.99 (10%)

Savings include $8.99 instant rebate. Offer ends 12/5/2021.

Kicker’s 46CSC654 6-1/2” 2-way car coaxial speakers sound incredible and, more importantly (for the folks looking for a simple, but noticeable, audio upgrade in their vehicle), they don’t need gobs of juice to perform well. The polypropylene woofer cones couple quite well with the PEI dome tweeters for well-balanced, natural sound. The tweeter on each speaker boasts zero protrusion, so you don’t have to be concerned with the tweeter hitting the inside of the door panel when you’re putting everything back together after the installation.

And speaking of installation, Kicker put a lot of time and thought into the fitment of the rear part of the speaker, too. Measuring only 1-11/16” in top-mount depth, this speaker system should have no issues being installed in virtually any vehicle. A pair of stylish protective grilles are included in case you need them, too. If you’re looking for even better sound, consider adding a small amplifier into the mix to enjoy these car speakers even more!
