Redefining “Entry Level”

Don’t just replace your speakers – upgrade them! At NVX, we set out to build an affordable speaker solution for audio enthusiasts on a budget; although priced to compete with other “entry-level” speakers on the market, the N-Series offer sound quality and reliability which blows the competition out of the water. The materials and designs used in the N-Series were carefully selected to provide the best possible performance.

A Simple Installation Process for Every Application

The speaker utilizes an integrated filter network, which makes installing these speakers as simple as connecting the wires and mounting them to the door. N-Series is available in 3-1/2”, 6-1/2”, 4”, and 5-1/4” round models, and 4”x6”, 6”x8”, 6”x9” oval models. So if you’re in the market for a speaker that’s more about thrills than frills, look no further than our N-Series Speakers!

Designed & Engineered for Accuracy & Durability

Our speakers are designed with durability and sound quality in mind without having to break the bank. The polypropylene cone material is strong, yet lightweight for accurate mid and low tones. The Nitrile Butadiene Rubber Surround supports the smooth, linear movement for optimal accuracy. The Stamped Steel Basket Provides a strong, sturdy foundation for a durable and long-lasting speaker. The High-Temperature KSV Voice Coil provides superior current distribution with effective heat dissipation. All these materials combined make for a powerful line of speakers.

The Silk Dome Tweeter Delivers Impeccable Clarity

One of our favorite features in the N-Series Speakers is the amazing tweeters. The rich treble in our speakers are reproduced with stunning warmth and smoothness thanks to the 20mm silk dome tweeters. This material is usually reserved for premium component systems, however we are offering this feature in our pocket-friendly speakers.

Frequently Asked Questions (FAQ)


NVX aims for a guaranteed fit across various makes and models. This 6x8" front speaker replacement package ensures a simple and hassle-free plug-and-play installation with no modifications required.
Yes. NVX's NSP68 speakers are highly efficient, meaning they produce great volume even with the lower power of a factory stereo. However, you'll get noticeable sound upgrades with an aftermarket stereo and amplifier.
You’ll get much cleaner mid-bass punch. While 6x8" speakers can't provide very low frequencies like subwoofers do, the heavy-duty magnets in this kit provide a tighter, fuller low-end that won't bottom out like the worn-out stock drivers.
1999-2002 Mercury Cougar uses 6x8" factory front door speakers. If you wish to use 6.5" speakers like NVX NSP65, you could use 6x8" to 6.5" speaker adapter brackets to create a secure fit.
Yes, NSP525 fits most vehicle applications, including the Mercury Cougar. You get a massive audio boost while maintaining the classic look of your vehicle interior.
You don’t need to buy more screws. Aside from your factory screws, NVX also has supplied you with 8 screws and 8 speed clips to help with your installation.
This specific package is only intended for the front door speakers. However, you can install NSP68 on the factory 6x8" rear openings of your vehicle.

Great upgrade speakers!

The following review is for NSP68, which is a part of the bundle you are viewing.

I installed four of these in my wife's Mercury Mountaineer to replace the factory speakers The sound is much better than the factory set and actually sound as good or better than any other 6x8's I have ever heard. Bass response is pretty good and clean for rock and country music and the tweeter sounds great, nice and crisp as it should be. Overall I am very happy with the sound and performance. I would buy these again without a second thought in the future for factory replacements and even on a small amp. I have these running directly off of a Soundstream VR-650B head unit.

Great for the price

The following review is for NSP68, which is a part of the bundle you are viewing.

I recently installed four of these in my 94 mazda with an Alpine head unit and they sound as good if not better than speakers I've payed double for. The bass response is surprising for only running off my head unit and the highs are nice and crisp. The vocal frequency is where these speakers really stand out. I would by the N series from NVX again and again. simply a great speaker at an absurdly low price.

Absolutely Terrific Value!

The following review is for NSP68, which is a part of the bundle you are viewing.

I installed 4 of these speakers in my '93 T-Bird! You couldn't ask for a better price on these 80 watt speakers. I think the quality is better than the original JVC 70 watt speakers. Well done Sonics, and thanks for the excellent deal on these speakers.

2014 F-150 speaker upgrade

The following review is for NSP68, which is a part of the bundle you are viewing.

I ordered direct replacement speakers from Sonic Electronix for my 2014 F-150, I just wanted something more reliable then the factory speakers, I purchased the NVX-NSP68 install was simple and they sound great. Sonic's website was user friendly and shipping was on time.

Happy with purchase

The following review is for NSP68, which is a part of the bundle you are viewing.

Overall great product for the buck. Much better sound quality over stock speakers. Didn't notice a difference in sound quality between stock and nvx until adding a 300 watt amp to power 4 of these speakers in my 06' ford explorer. I installed a Clarion XC1410Compact 4-channel amplifier — 50 watts RMS x 4, and it woke the speakers up. Sounds great and gets loud. No problems so far. Matched these speakers with two 10inch kicker cvr102 subs 400rms dvc wired at 2ohms with a 600 watt amp. Happy with these speakers, I would buy nvx again.
