Rockford Fosgate R168X2

Rockford Fosgate R168X2

The Rockford Fosgate R168X2 speakers come as a pair of 2-way full-range coaxial ones with clean all-black design. They look minimalistic and don’t stand out from your car’s interior. The R168X2 provide 4-Ohm impedance and 110W (55W RMS) max power handling which meet the CEA-2031 industry standards. That is why we placed them among the top-rated 6×8 car speakers.

Each speaker is equipped with a half-inch silk dome flush mounted tweeter. It creates a refined and warm sound which is especially suitable for jazz songs. The integrated concealed high-pass crossover serves for tweeter’s protection and optimizes speaker’s frequency response from 51Hz to 20kHz. It’s hidden inside the stamped steel basket which creates a cleaner look and contributes to easier installation. The cone is made of vacuum-formed polypropylene and prevents crossover from the need of extra wiring and ensures a mighty sound with quick transitions. Generally, all drivers are efficient and work great in providing genuine stereo audio.

These 6×8 door speakers feature a rubber surround. It helps the cone move linearly and also allows for better excursion.

They feature a lower-than-average sensitivity rating of 87dB and shallow mounting depth (2.54 inches). The kit includes all the necessary hardware for mounting so you won’t have to buy anything separately. The speakers have spade terminals, so installation won’t be an issue. However, they may require some tweaking to create clearance.

Pros

  • They are verified by Klippel certification program.
  • The R168X2 are marked as marine ones, so they are weather-resistant, and accidental ingress of water can’t damage them; they also can be mounted on water transport.
  • The speakers produce an excellent sound even without an amplifier.

Cons

  • Some distortion and clipping are heard at particularly high volumes.
  • The bass is a little short for such genres as rock and hip-hop.

They have black-on-black design and look simple. The FlexFit basket frame that uses slots instead of holes allow you to slightly adjust the speakers for a better fit.

The speakers have 0.75-inch PEI dome tweeter which contributes to an accurate frequency reproduction. The integrated concealed crossover is located inside the basket which simplifies the installation process. The high-strength mineral-filled injection-molded polypropylene cone is sturdy and lightweight at the same time. The light weight eliminates cone flex for improved sound quality.

Thanks to butyl rubber surround, they are not prone to rotting and can withstand hours of high-volume jams. The P1683 speakers have wide (65Hz – 24kHz) frequency response which ensures decent quality regardless of the genre of music. In general, they are able to provide great full-range sound but definitely require an amplifier.

The Rockford Fosgate P1683 use the Vertical Attach Surround technology that increases the speaker’s effective radiating cone area up to 25% by eliminating large flat surface area.
These 6 x 8 speakers from Rockford Fosgate feature a mounting depth of 2.32 inches. The kit includes everything you may need for easy and quick installation: mounting hardware and OEM adapter plate which has the “break-away” tabs that can be detached to fit all sizes.

The balanced dome tweeter creates strong frontward sound. It features a sound field enhancer design which works to create a wider sound field by developing the tweeter’s shape.

These speakers also feature an acoustic sound harmonizer. It provides smooth, natural sound by controlling woofer’s sound waves, so only certain frequencies can pass through the holes of tweeter’s panel.

The yoke and plate are designed to work as a heat-releasing mechanism since they are painted in black. Thanks to that, the heat efficiently releases inside the magnetic circuit to keep the voice coil cool. This significantly contributes to an increased service term, so they are among the best 6×8 car speakers in terms of durability and can withstand some heavy usage.

Buyer’s Guide

The Reasons to Choose 6×8 Speakers

6×8 speakers are not just the most prevalent size of speakers for cars. They also can offer a number of great characteristics. For example, they are lightweight and usually come with almost everything to make the sound as great as possible. Most of them include woofers for low frequencies and decent bass reproduction, tweeters for high frequencies, as well as midrange drivers.

In terms of power handling, the 6×8 speakers may vary from 140W to 300W (and even more in some cases) which is enough for many. The frequency response usually varies from 40Hz to 20kHz and more.

What to Look for in 6×8 Speakers?

When you need speakers of a certain size, you may face some limitations. This way, when making your choice, look for a product that uses space more efficiently, being more responsive, and creating more accurate sound.

Bass response

Before choosing 6 x 8 speakers, you should decide on how much bass do you need, as it may be a problem in a limited space car. If you consider bass to be very important, it’s better to look for some 2.1 setup for your car. It must contain special speaker dedicated for low frequencies.

Amplification requirements

Your setup largely depends on the speaker’s amplification powers. You need to know the number of channels available, and on which power and impedance they work. There are also some amplifiers with universal channels that can give you more opportunities.

Component vs coaxial

Component and coaxial speakers have their advantages and disadvantages. Let’s take a closer look at them so you could decide for yourself which ones are better.

Component speakers are a set of driver systems. They may come with separate woofer and tweeter. They require the installation of a separate crossover for correct direction of sound frequencies to drivers. Such speakers are able to ensure dynamic sound, but it’s not so easy to install them as they must be installed separately.

Coaxial speakers have the drivers built into one unit. Accordingly, woofer and tweeter aren’t separated and come as a part of one speaker, creating a 2-way driver system. They also frequently come as 3-way driver systems which have such three drivers as woofer, midrange driver, and tweeter. They have two substantial advantages: easy installation and full-range sound provided by one unit. However, they are not the greatest solution for dynamic sound.

Power and sensitivity

You should pay special attention to power and sensitivity ratings to avoid the risk of burning out your new speakers. This way, you should be aware of the max amount of power that a speaker you are going to obtain is able to handle it. In case you have to connect your new speakers to an external amplifier than ensure that they and the amp don’t differ too much in terms of their output power (it’s usually given as watts RMS). Additionally, if you connect them to an amp, it’s necessary to select the speakers with low sensitivity rating (marked in dB). However, if you don’t intend to connect them to an external amplifier, you shouldn’t worry too much about the sensitivity rating.
