I want to build a system for my 1975 Chevy C10. I want he cd player to have an aux in and be kinda high in the watts. My truck is real loud. I just want two rear speaker and some tweeters for now. I will want to install a sub later on. I just need to know what I should buy. E Bay works great for me. I don't want expensive. Something that sounds good and will last. I'm looking at for the player and the speakers and tweeters for right now at about 120 bucks. Any help will be great. Thanks
