Best 15 Inch Car Subwoofer Reviews (Updated List)

1. Skar Audio ZVX-15v2 15 Inch 1500 Watt Car Subwoofer

Skar Audio ZVX-15v2 15 Inch 1500 Watt Car SubwooferIf your sound system needs a pick-me-up this 15 inch Skar Audio subwoofer for cars will do the trick very nicely. It can take a very ordinary vehicle sound system and instantly turn it into a much more dynamic one.

This 15-inch car subwoofer is jam-packed with nice features. It has a 1500 watt true RMS power and can handle up to 3000 watts peak power input. The Skar Audio ZVX-15v2 also features a huge triple stacked magnet and great quality pressed paper cone for improved low-frequency sound reproduction.

You will be rocking in your car seat to the rich bass sound that comes from this subwoofer.
One of the things that we really like about this Skar audio product is the way they stand behind it. It comes with a full 2-year warranty which is unusual for a subwoofer because of how easily that can be damaged if not hooked upright.

  • 3000 Watt peak power
  • Triple stacked magnet
  • High quality pressed paper cone
  • Dual 1-Ohm voice coil configuration

2. Kicker S15L7 Car Audio Subwoofer

Kicker S15L7 Car Audio SubwooferThe next subwoofer we will review for you is the Kicker S15L7 Car Audio Subwoofer. The description notes that it peaks at 2000W and functions on an everyday basis at 1000W. Nevertheless, the recommended power range is between 500 and 1200 Watts RMS. Stick to this range to protect your subwoofer. It can fit in various car models as long as it has a custom cutout box or spot where it can fit. Go for a bigger box if you have to choose because it will eventually blow in a box that is too small. The voice coils are not made from the most durable material, but they provide good sound. It can reach a very high volume. At low volume, however, the sound could be distorted, making it difficult to listen to mellow or lighter notes. The speaker can wire 2ohms and 4ohms. What you choose depends on the amplifier and how much power it will put out. Ohms are related to resistance: the more resistance, the lower RMS Watts you get.

Pros:

  • Nice sound on high volume
  • Compatible with multiple car models if placed in the right box
  • Can wire 2ohms and 4ohms
  • Affordable

Cons:

  • Distorted sound at low volume
  • Could blow easily if overpowered

  • Flex fit basket
  • 22-250 Hz frequency response

6. Skar Audio DDX-15 D4 Dual Car Subwoofer

As we have reviewed each of the three Skar Audio 15 inch car subwoofers that have made our list of the best ones we can’t help be impressed with the quality of them. The Skar Audio DDX-15 D4 is easily as impressive as the other two 15 inch subwoofer products that made our top review list.

Skar Audio promotes this subwoofer as competition quality and it really comes close to that.

8. DS18 EXL-B15.2D Competition Car Subwoofer

Affordable subwoofer which comes in couple different variants and has decent specifications. With the 3000 watts max power and 1800 watts, RMS power it is not the most powerful around but RMS power is solid. Red color aluminum basket with large foam edge and paper with glass fiber cone are the basic specifications of construction but using paper is really outdated but it offers some advantages.

The big magnet and dual coils work perfectly in delivering the sound and at this price, this is a good proposition for starter users.

9. Rockville RVP15W8 15” Pro Subwoofers

Rockville RVP15W8 15” Pro SubwoofersThe Rockville RVP15W8 is a pair of 15” Subwoofers. They have single voice coils that are capable of supporting a peak power of 1000W. However, do not try and reach this number before subjecting the subwoofers to a break-in process. Begin with the RMS of 500W and increase after a couple of weeks. When it comes to installation, the operation is fairly easy to perform. This model subwoofers perform well in a large sealed enclosure. You will need it to be at least 3.0 cubic feet. Note that it should not be a ported box as the sound will not be as good in one. These subwoofers produce moderate amounts of bass. You will like the result if you like more hit or punch type of sound. It is loud and overpowering so it will not be suitable for you if you prefer a deeper, lower bass. This unit comes at a reasonable price for a pair of two subwoofers. For optimal sound, purchase a powerful amplifier.

Pros:

  • Good for loud, thumping bass
  • Two single voice coil subwoofers
  • Straightforward to install
  • Decent sound for both the car and the house

Cons:

  • Not good for lower bass
  • Need relatively ample space

11. Rockville RWS12CA 12″ Car Subwoofer

Rockville RWS12CA 12" Car SubwooferThe Rockville RWS12CA 12” Car Subwoofer is a useful addition to your car. This isn’t a replacement speaker. It’s designed to be an add on. It has a built-in amplifier so you will have to provide 12V power and audio source. The amplifier is a valuable advantage because you will not need to purchase it separately. Moreover, the product comes with everything you need to install it. Mounting is fairly easy, but you need to make sure that you have enough space for it if you want it under your seat. The depth of the subwoofer is 12”; however, it is slightly longer because the cover adds a little more to the depth. It does not draw too much power, and it creates a decent sound. When it comes to frequencies, this subwoofer does not capture lows as well as it does mids and highs. This item is heavy enough that you might even not need to secure it. It will stay in one place. It would still perform well in a box. Nonetheless, the protective grill is plastic instead of metal, which automatically means that it does not make for the most solid construction.

Pros:

  • Decent sound
  • Good price
  • Heavy and stable
  • Built-in amplifier
  • All hardware and wiring included
  • Easy installation

Cons:

  • Plastic protective grill
  • Cover adds more to the depth
  • Weak low frequencies

Best 15 Inch Subwoofer

Some Key Spec To Consider Choosing A 15 Inch Subwoofer

  1. Strong Sound Isn’t Always The Best Sound
    The reason why you should buy the 15-inch subwoofer is the sound. The power and the thump of might bass. But, there is a catch. No doubt that the 15-inch subwoofers are the most powerful on the market but they are also known for having the biggest problems during sound reproduction. Since the cone and the magnets of the 15-inch subwoofer are very big they need a lot of time to move and produce the sound. In the case of playing a song with a fast beat, the subwoofer hasn’t got the time to play all the notes and keeps getting late, ruining the experience of the song. That is why when you are listening to a very powerful system you can still hear sounds from the subwoofer moments after the song has ended. So, the main thing in choosing 15-inch subwoofers has to be the sound and the reaction time. You need a speaker that is capable of playing all the notes as fast as smaller subs or speakers.
  2. Space Is Scarce
    Obviously, the 15-inch subwoofers need the biggest space and you need a box for them. If you pack everything correctly, you will lose your trunk or most of it. That is why you should choose 15-inch subwoofers only if you have a car big enough to carry all of that and still gave you some space for your stuff.
  3. The Vibrations Could Be Too Strong
    Since the 15-inch speakers have a big power they also produce a lot of very strong vibrations. You will notice that your car will shake and vibrate when you put the big power. However, the vibrations are much more dangerous than you think and the shared power of it can loosen your bolts, interior panels and even damage your car. So if you are planning to equip your car with full audio power and use it often, you might tighten your bolts and check them out occasionally just to see if everything is nice and tight you would have any problems.
  4. The Price Is Important
    Be ready to spend big if you are going for 15-inch subs. Some of the speakers are well over 1000$ and that is just the sub itself and you still have to build the box or enclosure, buy the cables and etc. So, think again, do you really need and can you afford this kind of power in your trunk?
