Ready to upgrade your car’s audio system with a new subwoofer? A 15-inch subwoofer is often the best choice for listening to music where a bigger boom is better.

Best 15 Inch Subwoofers

Peak Power: Peak power wattage is the maximum watt output the speaker can handle for short bursts. It’s important but also keep RMS power in mind.

Best 15 Inch Subwoofers

RMS Power: This wattage is the average or continuous power your subwoofer uses. It is the most reliable measure of the volume and sound you’ll get.

How to Find the Best 15-Inch Subwoofer

Ohm: This measures the so-called impedance of your subwoofer in ohms. The lower it is, the more easily electricity flows through the speaker.

Rockford Fosgate P3D4-15

Top Pick
Rockford: the name alone is enough to make you shiver in anticipation. This 4-ohm subwoofer features 600W RMS power and 1200W peak power for loud, intense sound. The 2.5-inch voice coil is copper-clad aluminum, with a “VAST” Vertical-Attached Surround for greater cone area and flex-fit basket design. The cone itself is made from thermal anodized aluminum, and a 102oz magnet completes the package. This powerful 15-inch subwoofer adds up to weigh just 25 pounds, so it won’t make your trunk sag. The warranty is pretty average among the subwoofers we targeted, too.

Rockville RVP15W8

Budget Pick
So you need a subwoofer, but your amp or receiver isn’t made to work with 4 ohms. Then 8 ohms it is!

Dual Nickel-plated banana plug terminals and a 51oz magnet put powerful materials behind you for powerful sound.

Rockford Fosgate P1S4-15

When every subwoofer around seems to be battling for the highest RMS and peak power wattage, you might be thinking: 250W RMS? 500W peak? Sounds low to me… But it can work for your system, especially if you have an amp with similar power output. It has a great build, too: a two-inch copper-clad aluminum voice coil, flex fit basket design, Kevlar-reinforced paper cone, and high-density poly-foam surround. Kevlar--now that’s tough stuff. The subwoofer also features a 54oz magnet and stamp cast frame structure. Have a low-watt amp that needs a big kick from a subwoofer? This one is a great option.

American Bass TNT1544

The American Bass TNT1544 is hardcore all the way through. A carbon kevlar woven backed with a non-pressed paper cone surrounded by layers of high-density double-stitched foam with conex spiders all inside of a cast aluminum basket: wow! The big 3-inch voice coil is on the large side among our top ten subwoofers list, plus the double-stacked 160oz magnet--this is a heavy-duty subwoofer! With a solid 92.6dB sensitivity rating, all of these cool specs mean you’ll get deep, booming low frequencies without breaking a sweat. Also, Kevlar? How cool is that!

Planet Audio AC15D

This subwoofer has a dual 2-inch aluminum voice coil with 4 ohms of impedance and 89dB sensitivity. The polypropylene cone and foam surround can handle a high workload, plus you get a customizable trim ring, just for fun! It has 1050W RMS power and a 2100W peak power for tons of powerful sound. The only downside: a super-short warranty of just 30 days, so make sure you test the subwoofer thoroughly and break it in early! It can be placed in a two cubic foot sealed or 2.98 cubic foot ported enclosure depending on the sound you’re looking for. It weighs a lightweight 16 pounds, so you don’t have to worry about weighing your trunk down!

Kicker 10CVR154

The Kicker 10CVR153 has an injection-molded double-stitched ribbed santoprene surround, high-temperature polyimide film voice coil, and tons of stitching and adhesive to keep the cone and the surround attached. A steel basket holds it all together with a powerful rear magnet. The sensitivity is 89.2dB with a frequency response of 25-500Hz. The use of polyimide rather than paper in the voice coil can have a slightly warmer sound as a result. Either way, you’re getting your money’s worth of intense bass! It’s not the most powerful speaker around, but it’s more than enough to amp up your car’s audio performance!

Skar Audio VVX-15v2 D4

The VVX-15v2 D4 subwoofer from Skar Audio features a stitched paper cone, foam surround, a heavy magnet and a solid body with a custom tooled basket for the 2.5-inch copper voice coil. The realistic RMS power is refreshing to see where most manufacturers try to boost theirs as close to peak power as possible! The sensitivity is a solid 87.7 dB, too, for accurate sound quality. The low frequencies are going to sound incredibly intense with this subwoofer! Hey: we also like the two-year warranty as a backup plan! Enclosed or ported, this Skar Audio subwoofer is made to impress.

Audiopipe TXXBD315

This big 40-pound subwoofer features a 220-oz triple stacked magnet and 3.3-inch four-layer voice coil. The powdered black steel basket adds to this heavy-duty subwoofer’s weight. But with a sensitivity of 97dB, you’ll get true low-frequency sound. You just need a mounting depth of 8.625 inches and a few other things! The RMS power is impressive, too, at 1200W, so you can blast your music through the roof! The big magnet and big voice coil are a powerful combination. The high wattage combined with the other features let you get low and get loud!

The Pyle PLPW15D is an unenclosed subwoofer with a black steel frame, non-press paper cone, and foam surround.

This is a great low-price subwoofer for entry-level car audio and has a good SPL. From hard rock to rap, you’ll feel and hear the bass! The only issue: we wish the warranty was longer, but that’s a common tradeoff of a low price.
