Frequently Asked Questions (FAQ)


NVX aims for a guaranteed fit across various makes and models. This 6.5" front door speaker replacement package ensures a simple and hassle-free plug-and-play installation with no modifications required.
Yes. NVX's NSP65 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.
No, this package is intended for 1990-1997 Mazda MX-5 Miata and these don’t have factory Bose audio systems. Even if you install NSP68 in a Mazda vehicle with Bose, its 4-ohm impedance would generate low power relative to Bose’s 1-ohm/2-ohm rating.
1990-1997 Mazda MX-5 Miata already uses 6.5" factory front door speakers. If you wish to use 6.5" speakers, then the NSP65 is the best entry-level option for your vehicle.
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.
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. There's also no need for extra hardware as the speakers already fit factory openings.
This specific package is only intended to replace factory front door speakers. However, NVX also offers a 3.5" rear headrest speaker replacement package for the 1990-1997 Mazda MX-5 Miata (Sold separately).

Great budget speaker

The following review is for NSP65, which is a part of the bundle you are viewing.

I put these in the front doors and some NVX 6x9s in the rear deck on a Cobalt to replace blown factory speakers. They were just running off the (extremely weak) factory GM radio.
I was very, very impressed with their performance for a budget speaker. The tweeters were bright without being too harsh, and the bass response was unreal for the tiny amount of power they were getting from the headunit. Now, they didn't slam like subs or anything, but it was solid bass.
I think it was

Great cheap speakers

The following review is for NSP65, which is a part of the bundle you are viewing.

I just installed these and I'm quite impressed. Clean highs that aren't overpowering, decent mids and much better bass than my stock speakers without distorting. I don't have them amped, I'm just running them off a JVC headunit but they still sound phenomenal with very little distortion at high volumes. I'll definitely be trying out other products from nvx.

great sound

The following review is for NSP65, which is a part of the bundle you are viewing.

Installed these in front and rear door of my hummer h3 to replace the crap factory ones. They sound awesome. Have them running off of stock deck no amp. Put out plenty of bass and clear and crisp highs

NVX 6.5" coax speakers

The following review is for NSP65, which is a part of the bundle you are viewing.

For the price, you are not going to get a better replacement or entry level speaker. Good sound though they do not come with speaker grills/covers so consider that, should you need them for your specific application.

Awesome Entry Level Option!

The following review is for NSP65, which is a part of the bundle you are viewing.

I put a set of these in my access doors in my Frontier a few months ago and love them. I have the 6x9 version in the front doors and am powering them with a MTX 4 channel at 55x4. The mids and highs are crystal clear and smooth. I prefer the silk tweeter on these to other options that have a more shrill or harsh sound to them. Can't speak to the way they sound on deck power or the bass response as they are running on a high pass crossover through the amp. I highly recommend them and the combo pack with a set of these and a set of the 6x9's is what I did. Phenomenal package deal for the value of these speakers.
