2-Ohm vs 4-Ohm Speakers

2-Ohm vs 4-Ohm Speakers

It’s well known that factory car audio systems aren’t satisfactory in the long run. Even speakers in luxury vehicles may not provide the right amount of oomph for your drive. Some manufacturers don’t make it easy to directly replace your OEM (Original Equipment Manufacturer) without having to overhaul the entire setup. 

NVX’s mission is to create a line of products that fill the space between those short-lived, off-the-lot systems and bank-breaking merchandise. For new audio enthusiasts, it can be difficult to know where to start shopping for a car audio upgrade. 

Factory stereos, also known as OEM, only produce a slight amount of power. You can expect roughly 20 volts per head unit. Depending on if the system comes amplified or not, not a lot of power will be flowing through your speakers.

Replacing your car speakers can be easy, but a quick search for car speakers reveals a plethora of 4-Ohm systems. While the most common impedance for a car speaker, their resistance means less power is flowing to the unit. If your goal is a simple swap to better speakers for a factory system, 4-Ohms and higher impedance won’t fix the initial problem.

NVX developed a solution for this exact dilemma. 

Say your current OEM system has 2-Ohm speakers that draw 100W – when these are replaced with 4-Ohm speakers, that power drops to 50W. The lower the impedance, the greater flow of energy that can run from the car stereo into the speakers.

A higher impedance speaker is useful for energy efficiency, to drive the equipment using less power. In theory, this means additional speakers can be added to the amplifier and head unit. In practice, the sound system could not be drawing enough energy to run the speakers at their full potential.

The “standard” 4-Ohm is not a worse speaker. The desire for a 2-Ohm system allows more power to flow from your head unit, or an amplifier. This means better volume, better quality and the oomph you want out of your car audio. 

The NVX V-series 2-Ohm speakers were developed as a response to this issue. The NVX VSP65 and NVX VSP69 are the audiophile's solution to an easy switch from a subpar OEM to a high fidelity sound system without costing you undue time and money. 


These NVX sets are comprised of 2-Ohm 6.5” or 6x9” component speakers, 1” Dome Tweeters, and two adjustable crossovers were developed as a direct solution to an aftermarket installation. A 2-Ohm component system like this, with two midwoofers and the two tweeters, allows for a more robust frequency range – better highs and clearer mid-range. 6.5” and 6.9” speakers can produce bass as low as 70Hz. 

The kit comes with two adjustable crossovers to divide and send the signals to the correct channels – keeping the speakers from working overtime on frequencies they’re not meant to produce. Each crossover comes with 0dB to - 3dB switch to take the edge off any extreme highs. 

The NVX VSP65 and NVX VSP69 are not just a quick fix for OEM replacement. The V-series are constructed with the same high quality materials we’ve come to expect from NVX, making them a choice quality replacement system for any level of audiophile. 

The midwoofer cones are made with polypropylene – popular due to their low distortion and its inability to absorb moisture. Silk, known for its strength, is utilized in the tweeters for high power handling while maintaining sound fidelity. 

Consider 2-Ohm speakers for your car audio – open up the possibilities with a system that delivers.
