Pyle PLPW15D: Check Price On Amazon

Pyle Plpw15d

Pyle is a renowned manufacturer of home and car audio systems that doesn’t disappoint.

Its subwoofers generally offer excellent performance and deliver crisp sound.  And the Pyle PLPW15D is no different. With 1,000 w RMS (root mean square) to 2,000 w of power, the bass from this subwoofer might just crack your windows if you’re not careful!

But the wattage doesn’t mean much if all you get are just loud noises and bass. A while back, I had what I thought was an excellent subwoofer – great specs, 1000w of power, 4 ohms, but horrible sound.

The speaker was loud, for sure. However, the sound quality was awful, to say the least, as the subwoofer sensitivity was only 80 dB.  I learned quickly that anything below 84 dB is a bad choice for those looking for excellent sound quality.

So, a good 15-inch competition subwoofer needs superior sensitivity (expressed in decibels) if it’s to deliver crisp audio with no distortion. 

Good news here, as the Pyle PLPW15D has an excellent sensitivity of 92 dB. You’ll be getting a strong bass and great sound quality with this competition subwoofer.

What makes the sound even better are the dual voice coils (DVC). This feature enables each individual speaker to deliver stereo sound, so you’ll get amplified audio and excellent speaker performance.

The Pyle PLPW15D also features superior construction, which should guarantee the subwoofer’s longevity. Its DVC, for example, is corrosion-resistant, making it a fine setup not just for your car but your boat as well (if you’re lucky enough to have one).

The high-quality foam surround which protects the cone and keeps it in place is specialty-treated for durability and reliability. The inner parts are protected by a black steel basket that’s quite sturdy and offers great visual appeal.

With a weight of around 11.21 lbs (∼5 kg), the Pyle is on the heavier side, but its installation is quite easy. The manual is detailed and straightforward, so as long as you follow the steps, you should have no problems installing this subwoofer.

Pros:

  • Elegant design
  • Clear sound
  • Easy installation 
  • Affordable

Cons:

  • Detectable vibration while turned on
  • High volume can impair sound quality

Rockville K5 W15K5S2: Check Price On Amazon

Best Budget 15-Inch Competition Subwoofer

Rockville K5 W15k5s2

The first subwoofer I ever owned was from Rockville Audio, and I kept on using it for years.

The company offers affordable products of decent quality that can prove to be quite valuable for budget-conscious consumers like myself.

The Rockville K5 W15K5S2 is a good quality device that can serve as an excellent upgrade to your standard car sound system.

The 2-ohm sub features program power handling of 1,000w and peak power handling of 2,000w, meaning it can deliver seat-shaking bass. The 90.8 dB sensitivity will keep the sound crisp and clear with minimal distortion at higher volumes.

This big boy has a frequency response of just 28.6 Hz – 1.0K kHz, giving you much better bass than you might expect from such an affordable product.

In essence, the lower the frequency range, the better and the deeper the bass, which means that the 28.6 Hz is sure to make some much-appreciated noise.

The cone is made of durable fiber-reinforced non-pressed paper, which increases the efficiency of the speaker, making it louder without actually needing more power.

What improves its performance even further is the thick foam surround and the paper dust cap that can boost performance even with a lower amp.

The Rockville K5 W15K5S2 has a 60 oz magnet that’s the lifeforce of this sub. While a larger magnet doesn’t necessarily mean a better subwoofer, the size certainly plays a part in its overall performance.

As a general rule of thumb, larger magnets (like 60 oz ones) can move the coil front and back with ease and deliver a better listening experience, giving the woofers more power.

When testing out the Rockville K5 W15K5S2, I’ve found that the installation is slightly more complicated than with the Pyle PLPW15D but still easily manageable.

I enjoyed the sleek subwoofer design and the elegant blue details that fit nicely with my dark blue car interior. Overall, I was pretty happy with the product, especially considering its budget-friendly price.

Pros:

  • Affordable
  • Deep bass and clear sound
  • Sturdy build

Cons:

  • More complicated installation than usual
  • Sound quality diminishes at higher volumes

KICKER 43C154: Check Price On Amazon

Kicker 43c154

Boy, did this sub shake me to the core when I installed it in my car! If you’re getting it, make sure to take the volume down a notch before you turn the music on.

Just looking at the specs, I didn’t quite imagine a very powerful competition subwoofer, to be honest.

With its 250w RMS and max 500w of power, the sub seemed even below average for my standards. I expected a half-decent bass and a sound that leaves much to be desired. But the sub proved to be quite the underdog!

It performs much better than many subs with seemingly more impressive specs, and I couldn’t but include it in this list.

With its peak power handling of 500w, frequency response range of 25 – 500 Hz, and sensitivity of 90.3 dB, the sound came out crystal clear with deep bass and excellent tones even at higher volumes.

Your heart will start pounding when you turn on the music, and you’ll feel the bass deep in your bones.

The KICKER 43C154 has a ribbed, UV-treated surround that’s sturdy, ensuring that the polypropylene cone remains in excellent condition.

The white double stitching is not only a subtle design choice but serves to bind the suspension and ensure the utmost reliability. What I truly enjoyed was the steel basket that’s incredibly durable, able to withstand even the harshest conditions.

The KICKER’s box is nicely vented, and from what I can tell, the air can move freely and help with heat management to keep the sub working well in all environments.

Of course, to ensure proper venting, you need quite a lot of space, so these subwoofers are sizable. Make sure you have enough room in your car to install them!

Overall, I was pleasantly surprised by the KICKER 43C154. Despite the seemingly poorer specs, it performs almost as well as some of the strongest competitors on this list.

It boasts better sound quality than expected, strong bass, and a great listening experience.

Pros:

  • Good spec combination for surprising performance
  • Great heat management with suitable venting
  • Stable steel basket

Cons:

  • Wiring is not included with the subwoofer
  • Large size

Best 15 Inch Competition Subwoofer Overall

Skar Audio Evl 15 D2

I might be biased, but Skar Audio EVL-15 D2 is my favorite. It’s the exact 15-inch competition subwoofer that I have in my car, and I wouldn’t change it for the world.

I’ve been using it for almost a year now, and its performance is unmatched. I wish I had something like this back in high school, as it would’ve been my ticket to the popular kids’ group.

Anyhow, let’s get started with the design first. This EVL is sleek and elegant. Even if you knew nothing about subwoofers, you’d know it’s the real deal just based on its appearance.

It’s obviously made using high-quality materials that cannot but catch your eye. The entire sub is pitch black, with only the white Skar’s logo standing out. This minimalistic design is what first drew me to the brand.

The Skar Audio EVL-15 D2 features dual 2-ohm subwoofers with a peak power of no less than 2,500 watts! Its astonishing RMS of 1,250 and sensitivity of 86.2 dB ensure extremely responsive, deep bass that can simulate a minor earthquake.

High and low tones are crystal clear, satisfying even the staunchest of critics. Every audiophile needs a sub like this in their car.

Whether you’re playing techno, dubstep, rap, or even classical, every tune will be nothing short of perfect as the sub boasts a frequency response range of 20 Hz – 250 Hz.

The sub can handle the most extreme of music lovers for extended periods without showing a sign of trouble. It’ll provide consistent and continuously powerful output regardless of how you use it.

For efficient bass reproduction, you need a sub with an appropriately large surface area and excellent surround. Unsurprisingly, the EVL has both.

The foam surround is of excellent quality, making the sub capable of producing exceptionally low notes like they were nothing.

The Skar Audio EVL-15 D2 is unmatched. It’s my absolute favorite subwoofer, better than any other I owned. Over the past year, I’ve been challenging it constantly, and it’s delivered nothing but perfect performance.

Rockford Fosgate P3D2-15: Check Price On Amazon

Rockford Fosgate P3d2 15

Last, but certainly not least, is the Rockford Fosgate P3D2-15. This powerful subwoofer packs quite a punch. I thoroughly enjoyed testing it and pushing it to its limits, and it never disappointed me.

The P3D2-15 was carefully designed to produce high-quality sound. Every spec and feature works to improve the overall listening experience, and if you’re a drum and bass lover, you might want to look into this sub.

The first thing you’ll notice is the beautiful anodized aluminum cone that’s resilient and can hold its ground in the most extreme of conditions.

Although the cone is already quite sizable, the oversized rubber surround increases the surface area even further. In turn, the bigger surface area handles stronger, deeper bass with ease.

Aluminum wasn’t the cone material of choice simply due to its elegant, futuristic design.

The material actually acts to improve heat dispersion. Aluminum handles high temperatures relatively well, and it serves to direct the heat away from the more sensitive parts of the sub, such as the voice coils.

The Rockford Fosgate P3D2-15 is a 2-ohm DVC that boasts peak power handling of 1,200 w and RMS of 600 w. Paired with a frequency response of 22 Hz, the sub delivers a pounding bass experience and excellent sound clarity.

It has a protective PVC magnet cover that ensures superior performance, and its overall build seems pretty reliable.

The P3D2-15 can handle high and low notes with ease, and it will deliver consistent performance over long periods of time, even if you enjoy more intense music.

Pros:

  • Durable and reliable
  • Excellent heat resistance due to the aluminum cone
  • Handles low and high notes with ease

Cons:

  • Deep bass at high volume can distort the sound
  • Needs an amplifier for top performance
  • Expensive

Advantages/Disadvantages of 15-Inch Subwoofers

15-inch competition subwoofers can either be absolutely incredible for you or a bad investment – there’s no in-between. Like any accessory or device, they’re simply not made for everyone.

They have their unique pros and cons, and depending on your specific needs and preferences – you might not enjoy them as much as others.

So, let’s first get into the 15-inch subwoofer advantages. If you enjoy deep bass while you’re listening to music in your car, larger subwoofers can be an excellent choice.

Their larger surface area gives them better capabilities and enables them to produce much deeper sounds, ensuring you can enjoy bass and lower frequencies to the fullest.

15-inch subwoofers aren’t simply loud. They’re powerful, delivering strong notes and making you feel the music in your bones.

They’ll have your chest pounding and your entire car vibrating. As mentioned earlier, they’re the only type of subwoofer that can actually make your car feel like a concert venue.

However, there are several disadvantages. Larger, more powerful competition subwoofers can handle boomy, resonant bass with ease, but the overall sound quality could be diminished.

Smaller 10- or 12-inch subs typically tend to provide much clearer sounds, rendering higher notes much more clearly.

There’s also the issue of space. 15-inch subwoofers are a hefty piece of equipment, taking up quite a lot of space regardless of where you install them.

If you have a smaller car, you’ll likely have a lot of difficulties during the installation process.

Although there are a few disadvantages, I generally enjoy larger, 15-inch competition subwoofers as they genuinely make you feel the music you’re listening to.

With this in mind, I know they aren’t for everyone. So, consider your options carefully, and get a sub that suits your style and preferences.
