Raine's Nissan Frontier Audio Upgrade Guide (Complete ...
The 2018 Nissan Frontier offered standard AM/FM stereo with 6 speakers and USB, . Speaker sizes vary by location, with front doors often 6x9" (2 ohm) and dash corners housing tweeters, supporting aftermarket upgrades with various sizes and power ratings (e.g., 35-100W RMS per speaker). Factory head units were basic, but aftermarket options (like 9" Android screens with CarPlay/Android Auto) are popular upgrades. 
Standard Factory System
  • Head Unit: Basic AM/FM with CD (often optional/trim-dependent).
  • Speakers: 6 speakers standard (locations varied).
  • Connectivity: Standard USB input. 



 Please ask any and all questions before bidding. The system worked perfect in my 2018 Frontier. There is a small repair on one dash tweeter but it works perfectly. A piece of e tape around the bare wire repair would ensure that it could never cause a problem if someone is sloppy with the installation. i would leave it as is. works great.
