The Rockford Fosgate R165X3 is a full-range speaker from Rockford. As part of Rockford’s Fosgate series, speaker is well-made and reproduces high-quality sound. Let’s review the Rockford Fosgate R165X3 car speaker.

Rockford Fosgate R165X3 Review

Are you looking for a great 6.5 inches speaker that doesn’t cost you an arm or a leg? The Rockford Fosgate series is exactly what you are looking for. The R165X3 is better than any OEM I’ve heard of, yet still in a favourable price range. You won’t get a spectacular ride, but you’ll enjoy it.

R165X3 specifications:

  • 6.5 size
  • 45 watts RMS
  • 90 watts peak power
  • 4 ohms available (standard)
  • 3-way speaker: midrange woofer, midrange tweeter and standard tweeter.


To start, when installing your speakers, it’s essential to discuss the size of the speakers you want to purchase so that they aren’t too big or too small for your car.

The Rockford, as mentioned, is a 6.5-inch speaker. That said, it’s neither too big nor too small for most cars and will probably be about the same size as the speakers installed in your car.

The midrange has a nominal diameter of 6.5 inches and a mounting depth of 2.15 inches. The tweeter is only half an inch in diameter.


Silk dome for the tweeter and softer highs – To allow great sound at high frequencies, the tweeter of a speaker must be made of a softer material, and silk is one of the softest materials that are very durable.

Because of this, when you play higher frequency songs on Rockford, the sound is clear, loud, and not dark or distorted.

Good build quality

It doesn’t make sense unless a great quality speaker doesn’t last long and delivers consistent performance. For this reason, Rockford offers well-made woofers, midranges and tweeters that are ideal for long-term use.

The woofer’s cone is made from vacuum polypropylene, one of the most suitable and used materials for midrange woofers, as the woofer handles the low end.

In contrast, the tweeter and midrange handle the higher frequencies. This is also one of the most durable materials you can buy while providing a pounding base that will please your ears and heart.

The woofer cone should be flexible and durable as it moves. It provides excellent sound and is unaffected by heat, cold, and sweat, so that you can use it for a long time.


The speaker has an attractive and aesthetic appearance. The R165X3 is a 3-Way speaker with its woofer, midrange driver and tweeter for a better sound experience. The R165X3 has a sensitivity of 91dB and an RMS of 45W.

The maximum power of the speaker is 90W, but as explained here, the maximum power is not as crucial as the RMS. The speaker’s impedance is 4 ohms, which is the standard for car speakers.

Light weighted

This lightweight speaker can be installed in a variety of cars. Its small size makes it suitable for small cars. They are easy to install, and replacing your old stock speakers with these will give you a much better driving experience.

The overall dimensions of the speaker are 8.3 x 16 x 4 inches and weigh just 4.6 pounds.

Rockford Fosgate R165X3 Features

Looking at the specs, the Rockford Fosgate R165X3 looks like a pretty good speaker. Rockford has some great features you need for a car speaker system.

The speaker is sturdy, giving it excellent build quality. A steel frame around the speaker will protect the speaker from hard blows. The rubber around the speaker is in the next row to protect itself and significantly improve its lifespan.

It is made of stretchy polypropylene material. Various long-lasting titanium and mylar materials were used to design the speaker’s tweeter.


There is no extreme bass from these coaxial speakers, but unlike what component speakers can do, you’ll love the audio quality of the R165X3. The speaker has a fantastic crossover which helps the speaker reproduce the sound of all frequencies without significant distortion.

If you continue to listen to the sound, even if you raise the volume, the speaker delivers a clear and clear sound. It stands out that Rockford has done well with their 3-Way speakers.

It is recommended to buy an amplifier to get the most out of these speakers. But even if it doesn’t invest, these speakers will suffice. The magnets are heavy and feel comfortable in hand.

The polished dome tweeter and sleek design in flat black are very attractive. All speakers in the Fosgate series come with a polypropylene vacuum moulded woofer, silk dome tweeter and stamped steel basket frame. If you decide to use the all-out Fosgate mode in your car, it would be a shame to mount the grill over the grill, as it looks a lot worse than the speakers themselves.

On the other hand, The R165X3 lacks good bass. The speakers are great for highs and mids, but you need a subwoofer to get the most out of them. If you don’t have a subwoofer and don’t plan on buying one, you might want to consider buying another speaker with a bit more punch.

These speakers will not satisfy audiophiles. After all, these speakers are at the bottom of the market, so they are budget-friendly. So you can’t expect the most impressive and great sound.

  • Cheap and durable
  • Precise mid and high frequencies
  • Well made sound
  • Easy installation
  • Average size to fit most cars
  • No additional equipment is required
  • All necessary mounting hardware included
  • Lack of average extreme bass or bass boost on small speakers
  • Slight distortion at high volume
  • Not marine certified


The Rockford Fosgate R165X3 is one of the cheapest car speakers. This isn’t the car speaker that can make your trip grand but enjoyable. That’s right! It’s not a lot of pockets, but if you don’t like what your car’s old factory speakers have to offer, it’s worth buying.

The professional car audio speaker offers good sound quality at a very affordable price. The Rockford Fosgate R165X3 speakers can significantly enhance your car driving experience with superior sound quality.
