I'm looking at getting new component speakers for my 09 silverado ext cab. I will be putting 1 12" sub in it. So i was wondering which component speakers would sound the best in a silverado with 1 12. I'm leaning towards the alpine type-r's or the JL c-2 650's because I have a price range around 300. But I would also like to know what im paying my money for and if anyone can give me some advice I would greatly appreciate it! thanks.
