I got new speakers for Christmas and I can't get them to fit in my car. The 4x6's fit perfectly in the dash but the 6x9's have magnets that are a lot bigger than the stock speakers (yeah, I'm pretty sure my old speakers were the 22 year old stock ones). They're hitting this piece of metal that goes to that roller thing that pulls out over the cargo area. So my questions are, what is that roller thing called?, how do I remove it?, and should I just throw it out or try to modify it so that I can keep it and still use the new speakers?
