I'm new to this site and i'm not too familiar with car audio. I'm 16 years old and i recently purchased a 1995 chevy beretta. I bought it from my boss and he took the back seats out and put a box in it with 4 15's. he gave me a planet audio 2250 mono block amp for the subs, thats it for the subs. the reason im here is because i dont know what highs and mids to buy. I was thinking of buying a pair 6x9's and getting a pair of tweeters, but i was also thinking of buying everything seperate ( Tweeters, midrange speakers, etc.). I understand this system isn't a "Rookie's" system thats why im being real careful of what I buy. Please someone give some advice ASAP! thanks in advance.
