Before you Begin

before starting work on your vehicle!
• Insure that your bass and treble settings are set to their default middle positions before
installing your new speaker upgrade. Once you’ve installed your Stage 1, you can reset the
bass and treble settings to taste. Keep in mind that we generally recommend keeping them both
very close to center as large adjustments introduce distortion into the audio signal and will lower
performance of your system.
• Perform the installation one door at a time. Since there are many small parts that you’ll remove
when completing the project, limiting the work you’re doing to one door will prevent you from
interchangeable.
