I believe I have the original factory speakers in my doors of my NA and they are horrible. Since my NA is my 'racecar' for autocross and track days (eventually) I don't care about having a kickass stereo set-up in it. I've got an old Sony Xplod head unit that's probably 10 years old but it works. I am looking for the best, cheapest speakers to replace them. Cheap meaning under $50 for the set. I know I'm expecting a lot, but I wasn't sure if there was a cheap option. I guess my questions is 'What is the best set of speakers I can get for $50'
