Frequently Asked Questions (FAQ)


NVX aims for a guaranteed fit across various makes and models. This 6.5" rear shock tower 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.
Yes, it could work with the factory Bose amplified audio system. However, these speakers could experience a drop in output due to the factory system's low-impedance output. It's best to pair these speakers with an aftermarket stereo and amp.
No drilling required! This speaker replacement kit includes custom Nissan-specific 3-bolt adapter brackets. They align perfectly with your factory holes for a secure, rattle-free installation.
No wire cutting is needed. This bundle includes plug-and-play wiring adapters that snap directly into your Nissan’s original factory harness clips for a fully reversible install.
Not at all. NSP65 is designed with high sensitivity. They require very little wattage to get loud, making them the absolute perfect drop-in upgrade. However, you'll never go wrong with buying an aftermarket stereo.
You don’t need to buy more 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 rear shock pillar speakers. However, NVX is also offering a 6.5" front door speaker replacement kit for 1990-1996 Nissan 300ZX (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.
