Audio you can pick anything from low to high ,, but you need to decide what kind of sound you are looking for. Also, you need to look at what kind of music you primarily listen to. For a decent front speaker and rear speaker it will cost you about 100 to 200 dollars. A dash kit will run about $200. Head units that are single DIN are 100-400. Double DIN head units with navigation and touch screens are 250-1500. Amplifiers are 150-400 for decent quality 1,2,4,5 channel amps. Subs are 45-300 for decent/good ones and boxes are 60-80 depending on 1 or 2 sub holes. Also install accessories ie speaker wire, amp wiring kits, and wiring harnesses.
To get a budget setup for just speaker replacement that will be cheap. But sound might not improve much. To overhaul and swap HeadUnit, Speakers, Amps, and Sub that will be about $1200. To get a good sounding system look about 1600-1800+
Give a bit more info on your music and what you want to do with your system. Then we can make some suggestions on products. What kind of music you listen to. Do you like sound quality or just want volume. Do you like warm vocals or higher sharp vocals. More midbass punch or more low end rumble. Do you listen to Pandora, iPod, cell phone or CDs. Do you need back up camera. Do you need audio-in input. Do you need navigation or do you plan to only do music with the head unit. Etc. Sent from AutoGuide.com Free App
