I'm a '14 WRX Base Hatchback. I would like to find a way to upgrade my sound system. I'm a music fan but not really a full-on audiophile. I don't need anything overly powerful, but i would like a little better quality and frequency range. I figure the first step is to go to a head-unit with more power and then upgrade speakers. Is just any head-unit with Bluetooth going to interact with my steering wheel buttons? Is this my best route to my goals or is there something simpler and less expensive?
I'm better with mechanical than electronics, so any other options in my budget area would be nice. I have been told there is a way to hook up some sort of inline amplifier with the stock system. I would like to spend less than $500, but definitely less than 1000.
Thanks for your advice!
