I recently bought kicker 40CSS684 6X8 component speakers to replace the factory for my 2017 Explorer. I need an adapter kit to mount the new 6X8 woofers. Kicker said it was a straight replacement but that's not the case. I have been checking all over the internet but can't find a 6X8 speaker adapter kit. I contacted Metra and their tech told me to use their Metra 82-5606 speaker kit which is a 6X9. Has anyone use this to mount 6X8 speakers or suggestion for me to use?
