The standard sound system on a 2021 Jeep Grand Cherokee L features six basic speakers, with higher trim levels offering nine or nineteen speakers. To upgrade the sound system on your Grand Cherokee, you’ll need to replace its speakers, subwoofer, and amplifier.
Ever since it was first introduced in 1992, the Jeep Grand Cherokee SUV has been an icon of rugged durability combined with stylish luxury—and the 2021 Grand Cherokee L is no exception. Like many Jeeps, however, the stock stereo system in the base trim level of the 2021 Grand Cherokee leaves a lot to be desired. 
If you have a higher trim level, your Grand Cherokee might have come with an upgraded sound system. If you have one of the lower trim levels, though, you’ll need to upgrade its system yourself in order to enjoy high-end audio quality.

What kind of sound system does a 2021 Jeep Grand Cherokee have?

The sound system in your Jeep Grand Cherokee L depends on its
trim level and package
. Here’s what each trim comes with:  
  • 2021 Jeep Grand Cherokee L Laredo: Standard 6-speaker system
  • 2021 Jeep Grand Cherokee L Altitude: Standard 6-speaker system
  • 2021 Jeep Grand Cherokee L Limited: Alpine Premium Audio System 
  • 2021 Jeep Grand Cherokee L Overland: Alpine Premium Audio System with the option for an upgrade to the McIntosh MX950 Entertainment System
  • 2021 Jeep Grand Cherokee L Summit: Harman Kardon Premium System with the option for an upgrade to the McIntosh MX950 Entertainment System
Each of these sound systems offers its own unique audio experience. Which one you have will greatly impact the sound quality that you’ll enjoy while driving your Grand Cherokee. Let’s take a closer look at each of the available sound systems and what they offer. 
Standard System
  • 6 speakers 
Alpine Premium Audio System
  • 9 speakers
  • Subwoofer
  • 506-watt amplifier
  • 19 high-efficiency GreenEdge speakers
  • Logic 7 multi-channel surround-sound
  • Active noise cancelation
  • Subwoofer
  • 825-watt amplifier
  • 19 Custom-designed speakers 
  • LD/HP Speaker design to reduce distortion
  • McIntosh Power Guard for improved high-volume clarity 
  • 10-inch subwoofer
  • 950-watt, 17-Channel amplifier 
If you have a McIntosh or a Harman Kardon sound system, you may not want to alter it with any aftermarket upgrades—those systems are already fairly high-end. If, on the other hand, you have a standard or an Alpine system, upgrading your stereo equipment could provide a significant sound quality improvement. 
If you’re not sure which system you have, check the logo on the speaker that’s located on the driver’s side door. It should have either a McIntosh logo, a Harman Kardon logo, or an Alpine logo. If there’s no logo at all, that means you have the standard stock system.

How to upgrade a 2021 Jeep Grand Cherokee sound system

Regardless of which trim level you have (or even what model), upgrading the sound system in any car involves replacing the same three components: the speakers, amplifier, and subwoofer.

Start with speaker upgrades

First, you’ll want to purchase new speakers for your Jeep Grand Cherokee. The speakers are the front line of your sound system and have a dramatic impact on its overall quality. 
Of course, you won’t want to install the new speakers yourself (unless you happen to have extensive experience working on automotive electronics). You’ll need to hire a professional technician to do the actual installation. Your main responsibility will be picking out exactly which aftermarket speakers to use. That’s not an easy task since there are so many options. 
To make things simpler for you, we’ve picked out a few recommendations from the most popular speaker upgrades for the 2021 Jeep Grand Cherokee L. Take a look! 

Pump up the bass with a subwoofer

Next, you’ll want to upgrade your Jeep’s subwoofer to boost the bass tones and get your floorboards shaking! For the 2021 Jeep Grand Cherokee L, you’ll want a high-end aftermarket subwoofer, such as the
Audiofrog GS690

Boost the power with an amplifier

Lastly, you’ll want to replace the amplifier—which is the most crucial component in the entire system. The amplifier determines the power level of the audio signal that’s sent to your speakers—meaning it’s the part that most directly determines the overall audio quality. 
The stock amplifier in the 2021 Jeep Grand Cherokee L (even the base trim) it’s actually fairly impressive. You shouldn’t necessarily need to swap out the stock amplifier in order to achieve top-tier sound quality. Of course, you could always invest in the
JL Audio Monoblock Class D Subwoofer Amplifier
($399.99) if you really want to push your sound system to the next level.
