This covers the first 30 minutes of troubleshooting an existing install. This will also cover any troubleshooting that you would like me to assist you with over the phone or private messenger. 
This is my minimum charge.
If you would prefer FREE troubleshooting then please join my private group and ask your question to the group,  I will try to check in as often as possible and help for free in the group, on my own time schedule. www.Facebook.com/groups/CarAudioInstall*when you purchase this troubleshooting you will need to select in store pickup to avoid paying for shipping costs on the website. Thank you!
