A:AnswerI bought these speakers and got speaker harnesses and just unbolted the speakers and plugged them in myself. It was very easy and I’m not very handy! I would recommend doing it yourself if you have the extra time! It didn’t take long at all and I only needed the tools that came with my Jeep and a screwdriver!
A:AnswerThere is no MSDS documentation for JBL GX628. Material Safety Data Sheet is for portable speakers that contain lithium-ion batteries. If you have more questions, please reach out to our Customer Support. http://bit.ly/30JI2G4
A:AnswerMost of our car audio speakers will work well with factory system amplifiers. Our JBL GX602 can handle up to 180 watts or 2-60 watts. We'd like to know more information about how you're planning you're set up. Please reach out to our Customer Support. We're here to help. https://support.jbl.com/us/en/
A:AnswerThey come with brackets in the box so if those don’t fit I’d recommend going into your nearest Bestbuy so they can see what harness or adapters you may need.
