Okay, here's the deal. I like punk music, so as you can understand I really am not that interested in having a very powerful audio system. I don't want to have to buy an amp. Right now my CD player says it can output 4 x 45 watts. I'm assuming the speakers I have now are not 45 watts, cause they sound really wimpy. What type of speakers would you recomend I replace the stock speakers with? I just want better sound really. Any suggestions?
