Audio
The 4Runner has some decent audio out of the gates, but some audiophiles out there think it’s a bit lackluster. There are hundreds of mods out there to choose from when it comes to audio upgrades for the 5th Gen 4Runner. You can upgrade the door speakers, rear hatch speakers, dash tweeters, head units, and even go as far as sound deadening the entire 4Runner. Whatever audio upgrade you’re looking for, you will find it on Trail4R.com.
