I just got rid of the old stock unit for a sony MP3 player to take it's place. I love it. Now I think I need to ditch the stock speakers for some new ones. Any ideas for decent low price? Are the sony Xplod's any good? I have an Xplod head unit. How about the Xpold amp's and subs? I'm thinking of two 8" subs or 10"s. They'll be in the back shelf with the 6x9's beside em.
