Have you ever wished that your Jeep Wrangler had better sound quality? Maybe your speakers don’t sing as well as you’d like, or your underwhelmed by the quality of the bass. This guide will show you how to install a stereo and speaker system to your Jeep Wrangler. Stereo upgrades are entirely modular. If you just want to upgrade the speakers, then that’s fine, but if you want to push more out of those speakers, you’re going to need to install an amplifier.

Step 2 – Replacing the front speakers

To access the front speakers, you’ll need to remove the side panels, glove box, and the lower dash panels. These can all be pried off. For the glove box, you’ll need to squeeze on the sides and then pull it out. On the driver’s side, you’ll need to unbolt and remove the instrument panel in order to get the speaker box out. The speaker boxes are fastened by two bolts on the side and one bolt on the back. Getting the speaker boxes out can be tricky because you need to rotate them downwards to get them out. Once the speaker boxes are out, you can remove the speakers by undoing the three screws on the front and unplugging the connector. Do the same thing in reverse to install your new speakers.

Step 3 – Replacing the tweeters

After dealing with the front speakers, the rest of your speakers are going to seem easy. The tweeters are easily pried out of their housings at the top of the dash. Disconnect the small speaker and install your new ones.

Step 4 – Replacing the sound bar speakers

The rear speakers on your sound bar are also super simple to replace. Just remove the three screws holding the speakers to the sound bar. Be careful so that the speaker does not fall when you remove the last screw. Then unplug the connector. Plug your new speaker in and fasten it to the sound bar.

Step 5 – Installing an aftermarket amplifier

To round off the stereo system, you’ll need an aftermarket amplifier. If you have the Infinity sound system factory installed, then you already have an amplifier installed below the driver’s side dash. If you’re installing a new amplifier, you’ll need to get more creative. Typically, aftermarket amplifiers are installed in the trunk.

You’ll likely need to fabricate your own bracket or modify one to mount the amplifier. The hardest part of this step is the wiring. You’ll need to directly power your amplifier from the battery. Make sure you have an inline fuse installed to your power wire. Route wires along the sides of the interior. You can pry off the clips holding down the corner side panels and pull up the carpet enough to move your wires through to the trunk. Don’t power your amp just yet. You’ll need to ground it first. Find a point where you can reach the chassis, clean the metal of any paint or rust, then drill a bolt down to the chassis. Hook up your ground to the chassis bolt. Next, you’ll need to hook up your amplifier to the rest of the system. Route your speaker wires and head unit wires to the amplifier on the opposite side from your power wire. Plug in your wires and your power. Turn on the amplifier as well as the stereo to test and adjust to your liking.

Pro Tip

You can also easily add a subwoofer into the mix, but this will cost you some space.
