does anybody know who makes a speaker for the opening in the middle of the dashboard. I only have the 3.5" speakers on the left and right sides of the dash board. There is a speaker in the LMC Truck catalog (38-8517) but I want something that can handle more power. I would take off the dash but I have done it before and it is just too much work. Just wanted to see if any of you would know so that I wouldn't have to take it off. I have an 86 k5.
