A Good Subwoofer = The Ultimate Back-Seat Driver.

A good subwoofer is like putting a live band in the back seat, with a rhythm section you can feel even when the music is low. A great subwoofer will have you looking for the long way home, so you can enjoy more of your music – as loud as you like. But which one should you get? Subwoofers for the car come in all sorts of variations, and at all price levels. 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. And that’s what our “Best Car Subwoofers of 2021” list is all about: our car audio experts cherry-picking the best on the market, by category.

Questions along the way? Don’t hesitate to pick up the phone and talk to one of our mobile technicians at our Route 309 Montgomeryville locale (215.368.8343) or email us here.  (You will make their day – they love this stuff.)

Kicker’s L7-series 41L7154 is an absolute monster. The formula for its square subwoofers is simple: more cone area = more bass response. Well, we’ve determined that this is 100% accurate! Boasting 1200-watt power handling and dual 4-ohm voice coil design, this bad boy packs a serious punch (think Bruce Lee) and would do well in a sealed or vented enclosure. Kicker’s Uniplate™ technology keeps the subwoofer efficiently dissipating heat so it can keep bumping for as long as you need it to. A Santoprene™ rubber surround corners ensure tight and accurate control of the massive square woofer cone for distortion-free listening at almost any imaginable volume!

41L7154 15" Q-Class L7 Subwoofer w/ Dual 4-Ohm Voice Coils

  • Subwoofer Size: 15" (square)
  • Continuous Power Handling: 1200 watts
  • Nominal Impedance: 2 or 8 ohms (dual 4-ohm voice coil design)

The Kicker 42CWQ124 car subwoofer may very well be the king amongst kings when it comes to 12” subwoofers. Seriously. It’s capable of handling up to 850 watts without breaking a sweat while requiring only 0.88 cubic feet of internal volume in a sealed enclosure (meaning it doesn’t need a HUGE box to perform quite well). The subwoofer’s SoloKon™ injection-molded polypropylene cone is backed with special bracing to ensure strength and maximum output. You’ll be rattling your trunk apart in no time! This strong woofer cone is married to the frame of the driver via a Santoprene™ rubber surround for the utmost durability. The 42CWQ124’s dual 4-ohm voice coil design offers flexibility in wiring a single (or multiple) subwoofer(s).

42CWQ124 12" CompQ Subwoofer w/ Dual 4-Ohm Voice Coils

  • Subwoofer Size: 12"
  • Continuous Power Handling: 850 watts
  • Nominal Impedance: 2 or 8 ohms (dual 4-ohm voice coil design)

8” subwoofers can be a little underwhelming, but that can’t be said about Kicker’s 8” 43CWR84. Sporting a dual 4-ohm voice coil design, this little fella can handle up to 300 watts continuously without running itself ragged. The UniPlate™ backplate and pole piece assist in providing efficient heat dissipation while the injection-molded polypropylene woofer cone belts out excellent bass response. The robust rubber surround is stitched to the woofer cone and then adhered to the basket of the driver for long-lasting performance. Small sealed enclosure volume requirements (0.40 cubic feet) round out this “small but mighty” subwoofer.

43CWR84 8" CompR 300-Watt Dual 4-Ohm Voice Coil Subwoofer

  • Subwoofer Size: 8"
  • Continuous Power Handling: 300 watts
  • Nominal Impedance: 2 or 8 ohms (dual 4-ohm voice coil design)

Car subwoofers are great, but sometimes they can be so large that they just take up too much room in the trunk or don’t fit behind your truck’s seats. Allow us to introduce JL Audio’s CS110LG-TW1-2 to you. Measuring only 15” W x 11-3/4” H x 5-1/2” D, it doesn’t take up much valuable real estate, but adds the impact that your current system is sorely lacking. This 2-ohm enclosure mates up perfectly to a 300-watt monoblock subwoofer amplifier (we have a few of those if you find yourself in need of one). The enclosure is crafted from 5/8” MDF (medium density fiberboard) to help eliminate resonance and wrapped in a durable black automotive-grade carpet with “JL Audio” stitched in white on the top. The enclosure is finished off with a steel mesh grille to help protect the subwoofer from foreign objects.

CS110LG-TW1-2 2-ohm 10" TW1-Series Subwoofer with Compact Enclosure

  • Subwoofer Size: 10"
  • Continuous Power Handling: 300 watts
  • Nominal Impedance: 2 ohms
  • Dimensions: 15” W x 11-3/4” H x 5-1/2” D

“Tube”-shaped car subwoofer enclosures aren’t a new concept, but, man, does Kicker really hit the mark with their 46CWTB82 piece. This sturdy tube-shaped ABS plastic enclosure is designed to stand vertically or laid horizontally (and the proper mounting hardware is provided for both options), so it won’t have too much of an impact on your vehicle’s available space. A Kicker 8” CompR-series 2-ohm subwoofer is loaded into one end of the tube while a passive radiator (a motorless subwoofer) is loaded into the opposite end to help enhance the bass output. Both drivers are protected from harm with the included grilles. This enclosure is looking for about 300 watts of continuous power to perform to its utmost potential. As a bonus, this enclosure is weather-proof, so a little moisture isn’t going to hurt it. Make good music sound great with this little wonder!

46CWTB82 8" 2-Ohm TB-Series Subwoofer Enclosure w/ Passive Radiator

  • Subwoofer Size: 8"
  • Continuous Power Handling: 300 watts
  • Nominal Impedance: 2 ohms
  • Dimensions: 8-1/2”W x 8-5/8”H (horizontal) or 13-7/16”H (standing vertical) x 12-7/8”D
