Top 7 Reasons Rockford Fosgate R165X3 is an Excellent Choice

Appealing Aesthetic Design

The model has a flat-black and sleek design with its glossy dome tweeters. They look clean, chic, and attractive unlike other brands and models that don’t quite fit the bill.

Great Sound Experience

Since it’s a 3-way speaker, it has midrange drivers, woofers, and tweeters, promoting a better sound experience overall. The old R165 was just a 2-way speaker, and it definitely didn’t sound this clear.

Highly Durable

The speakers are surrounded with steel frame to protect it from unwanted hard hits. There’s also some rubber around it to further promote protection and secure the item’s longevity. The product is also made with an elastic polypropylene material. And the speakers’ tweeters are designed with Titanium and Mylar materials to make them stand the test of time.

Fantastic Crossovers

With these fantastic crossovers, Rockford Fosgate R165X3 Car Speakers can play sounds of any frequency without a lot of distortion, making it way better than the previous models. Technically, crossovers are the component that produces certain frequencies to the drivers. When gotten right, the drivers get to generate sound of better quality. The crossovers of R165X3 are designed with high-quality materials that generate high-quality music all the time.

Safe Speakers

R165X3 has many superior quality grilles to promote safety. They’re installed on the front end of the speakers. The back end also inhibits foreign objects to hamper their performance.  It’s good to know how they have paid attention to detail on this sought-after model.

Lightweight & Low Impedance

Since it’s lightweight, installation becomes a breeze and portability is not a problem. In terms of impedance level, it has low impedance which makes installation of multiple extra amplifiers possible. Thus, expect to enjoy even more enhanced music from coaxial speakers.


These speakers aren’t the cheapest available, but it definitely falls on the affordable and budget-friendly range. If you take a look at all its features, you would understand why many people choose it—it’s not that pricey given its amazing inclusions.
