What kind of Audio System Should I get for my car.?

It depends on what music you listen to country and rock are good with 10's, some counrty, rap/hip hop are good with 12's and if you listen to low bass rap or whatever songs is good for 15's and up and how many really depends on what you want if you want to be loud get two or more and if you think you have enough room in the car, or if your just lookin for some bass so the system sounds better just get one in a bigish ported box and hell that will slam hard too.

Check out this website they have everything for a very very cheap price!! http://www.sonicelectronix.com/

My advise to you is to get what you really want if your starting from the ground up right now since its winter in most places this is the best time to do your homework and start piecing up the perfect sound if you do this wright you can get a great system for around that much: Right now the MB Quartz are the best speakers in the world their studio speakers, I know their 6x9's come in components which is incredible to give you prologic sound to your car without adding a sub! Just don't go into stores asking for them, they will charge you about 500-800 a pair order them online for about 150 a pair... Be careful their are "Fakes" out their real MB Quartz are made in Germany! This is were i bought mine from: http://www.sonicelectronix.com/m41-mb-qu%E2%80%A6 and if you don't believe me check out their frequency response compared to all the other speakers you will be shocked! This is also the cheapest place to buy your head unit also and their certified by BBB i bought my whole system from them and cost me under 1000 and people ask me all the time what the heck do you have in your car they think i have 10's lol
