Frequently Asked Questions (FAQ)


NVX aims for a guaranteed fit across various makes and models. This 5.25" rear door 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.
Yes, it could work with the factory Bose 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. 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.
No wire cutting is needed. This bundle includes plug-and-play wiring adapters that snap directly into your vehicle's original factory harness clips for a fully reversible install.
NSP525 is not built to be water-resistant and may destroy the speakers' circuitry. We highly recommend adding silicone baffles with drip roofs to fully protect the speakers from running water..
Not at all. The speakers in this kit are designed with high sensitivity. They require very little wattage to get loud, making them the absolute perfect drop-in upgrade for low-power factory Sierra radios.
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 door speakers. However, NVX is also offering a 6.5" rear door speaker replacement kit for 2007-2013 GMC Sierra (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.
