Frequently Asked Questions (FAQ)


NVX aims for a guaranteed fit across various makes and models. This 5.25" rear deck speaker replacement package ensures a simple and hassle-free plug-and-play installation with no modifications required.
Yes. NVX's NSP525 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 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.
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. The factory vehicle voice warning system is solely connected through the front-left driver's door speaker. Installing this rear deck speaker kit would not affect this feature.
Not at all. NSP525 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 mounting brackets, 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 door speakers. However, NVX is also offering a 6.5" rear deck speaker replacement kit for 1985-1986 Nissan Maxima (Sold separately).

Great Backfill

The following review is for NSP525, which is a part of the bundle you are viewing.

I purchased these to use as backfill in my NVX system and I am pleased to report that they have met my expectations to a T. They are plenty clear, and handle the power I am throwing at them very well. Like most speakers of this size and design they are limited by how much bass they can produce, but for rear fill in a system they are perfect. My kids say this is a huge improvement over the Bose speakers they replaced.

Great bang for the buck

The following review is for NSP525, which is a part of the bundle you are viewing.

So far, NVX hasn't let me down with anything I've tried. While these speakers certainly aren't "audiophile" quality, they are without a doubt better than anything I've ever heard in the same price range. I have them running off of an average power H/U with no amp and they still supply plenty of clear volume.
