Pyle 8″ Dual Voice Coil Sub
Strengths
- Very low cost
- Dual voice coil
- Easy to wire
Trade-offs
- Paper cone distortion
- Weak bass response
- Plastic basket
The Pyle PLPW8D screams “budget,” and that’s both its strength and weakness. It’s one of the cheapest 8-inch subs available, with an 800-watt peak rating and dual 4-ohm voice coils for wiring flexibility. The 60oz magnet sounds impressive on paper, but real-world performance is underwhelming, owners report it distorts early and lacks punch below 40Hz.
The non-pressed paper cone and plastic basket don’t help. It’s fine for casual listening if you’re not pushing power, but it won’t hold up to high volumes or complex basslines. Compared to the Skar or KICKER, it’s a step down in every meaningful way. I’d only recommend this as a temporary fix or for ultra-low-budget builds.

How We Picked These 8 inch subwoofers for truck
Rather than a hands-on lab test, my research focused on a detailed comparison of published specifications and features across numerous 8-inch subwoofers designed for trucks. I weighed owner reviews from major retailers against expert opinions found in car audio publications. My assessment considered the broader landscape of truck audio, drawing on years of experience exploring vehicle modifications and sound systems. This helped me rank options based on real-world applicability and perceived value.
For this category, power handling and enclosure type were the most significant factors. Trucks often have larger cabins and more road noise, demanding subwoofers capable of delivering strong, clear bass at higher volumes. A well-matched enclosure – whether sealed, ported, or under-seat – is critical for optimizing the subwoofer’s performance and fitting the available space. I also prioritized durability, as truck environments can be particularly hard on audio equipment.
Specifications reliably indicate a subwoofer’s potential power output, impedance, and mounting dimensions. However, owner feedback proved invaluable for gauging real-world performance, ease of installation, and long-term reliability. Reputation and brand history also played a role, particularly when considering factors like build quality and customer support.

Choosing The Right 8 inch subwoofers for truck
Finding the right 8-inch subwoofer can dramatically improve your truck’s audio, but there’s more to it than just raw power.
An effective 8-inch subwoofer delivers accurate bass response, fits the available space within a truck cab, and matches the overall power handling capabilities of your existing audio system. Key considerations include enclosure type (sealed vs. ported), power handling (RMS and peak), impedance, and sensitivity. Owners often prioritize sound quality and reliability over sheer loudness.
Understanding Enclosure Types
The enclosure is arguably the biggest single decision. Sealed enclosures generally offer tighter, more accurate bass, ideal if you prefer a refined sound. Ported enclosures, on the other hand, are tuned to a specific frequency, delivering louder bass at that frequency but potentially sacrificing some clarity. For trucks, where cabin space can be irregular and resonance is a concern, a sealed enclosure often proves more predictable. Don’t underestimate the impact of enclosure volume; too small, and the subwoofer will struggle, too large and you lose efficiency.
Decoding Power Handling Specs
RMS power is the continuous power the subwoofer can handle safely; this is the number you should focus on when matching it to an amplifier. Peak power is a short-burst rating and is less indicative of real-world performance. Many factory head units lack sufficient power, so you’ll likely need an external amplifier. When considering a powered subwoofer, look at the amplifier’s RMS output to ensure it aligns with the subwoofer’s rating. If you’re exploring options for your other vehicles, checking out car subwoofers can provide broader context.
- A low RMS rating (under 100W) suggests a subwoofer best suited for modest systems.
- A mid-range RMS rating (100-300W) provides a good balance of power and control for most truck applications.
- Higher RMS ratings (300W+) demand a robust amplifier and are often found in competition-focused setups, and may be overkill for everyday listening.
Prioritizing Fit and Usability
Truck cabins aren’t known for being spacious, so physical dimensions are critical. Under-seat subwoofers, like the Rockville SS8P, are a clever solution for maximizing space, but they generally trade off some bass output for convenience. If you’re willing to sacrifice some cab space, a traditional enclosure offers more flexibility in terms of subwoofer choice and tuning. Remember to measure your intended mounting location carefully and consider how the subwoofer will affect access to other cab features. If you’re searching for more options, you might find some great truck subwoofers to explore.
A subwoofer that sounds fantastic on paper is useless if it doesn’t physically fit your truck. Always double-check dimensions and consider installation complexity before committing to a purchase.

Frequently Asked Questions
What impedance should I match to my amplifier?
A 4-ohm subwoofer is generally the most common and easiest to power, but 2-ohm subwoofers can draw more power from a compatible amplifier(s) for louder output. Check your amplifier’s specifications to confirm the minimum impedance it can handle safely.
Are pre-fabricated enclosures really worth the extra cost?
Yes, pre-fabricated enclosures offer convenience and are often tuned to optimize the subwoofer’s performance, saving you the effort of building one yourself. However, they may not perfectly fit your truck’s specific interior dimensions, so careful measurement is still crucial.
Can I use a factory radio with an 8-inch subwoofer?
Generally, no. Factory radios typically lack the power output needed to drive a subwoofer effectively. You’ll almost always need an external amplifier to get satisfying bass response.
What’s the difference between SVC and DVC subwoofers?
SVC (Single Voice Coil) subwoofers have one voice coil, while DVC (Dual Voice Coil) subwoofers have two. DVC subwoofers offer more wiring flexibility, allowing you to match the impedance to your amplifier more precisely, but aren’t always necessary.
I’m also looking to protect my truck’s interior; do you have recommendations?
Absolutely, investing in truck seat covers is a great way to safeguard your seats from wear and tear, especially if you frequently haul cargo or work in your truck. They also help maintain the resale value of your vehicle.
The Bottom Line
Choosing a subwoofer often comes down to balancing control with convenience. For the strongest all-around performance in a truck, I believe the Pioneer TS-A2000LB strikes the best balance of power, sound quality, and established reliability. It’s a solid choice for those looking to significantly upgrade their audio without getting lost in complicated tuning.
If space is at a premium, or you prefer a simpler installation, the Rockville SS8P is an excellent under-seat option. And for those seeking a pre-fabricated solution, the Goldwood TR8F offers a ready-to-go package. For anyone considering stepping up in size, exploring top 10-inch subwoofer models will open up even more possibilities.
Ultimately, remember that specifications tell only part of the story. The best 8-inch subwoofer for your truck isn’t necessarily the one with the highest power rating. Prioritize a good match between the subwoofer, amplifier, and enclosure, and don’t forget to consider practical factors like cab space and your personal listening preferences – and perhaps explore some truck bed covers to protect your investment.
