I have a full SSV works in my 2016 base. It has kick panel and head rest speakers with SSV amp and ntb3 controller. It is all the black plug and play plugs. Looking to install an aftermarket head unit. Can I cut the leads from these speakers and splice into my new head unit. The speakers have a black plug with a red and white wire coming out. Just wanting to see if I can splice into head unit or do I have to replace the speakers.
