I am looking to replace my speakers in the door of my 08 tahoe. I will have a amp going to them I think it's around 75x4. If any one could provide me with a list of option that would be great. Crutchfield said I should either go with Polk or JL. Not really trying to spend JL money right now. And the sub that will be in the truck will either be cvt12 or JL 10w3.
