Need advice on factory monsoon
I want to change out my head unit. I have a nice alpine cda-9815 that I will be putting in. The thing about the head unit is that I want to be able to use my steering wheel controls and be able to control the factory 12 disc in the trunk. I found the swi-x for the controls but was wondering if I needed to buy something for the 12 disc. Next question is, what speakers would the new deck be powering? Thanks
