I'm considering upgrading my speakers in my 02 WRX since I can barely hear it with the windows open driving over 60mph. It definitely doesn't have the clairity and power behind it that I'm looking for.
My question is:
Can I just upgrade the speakers without changing the head unit? Can I put an amp(s) on the factory wrx headunit? I'm hoping to keep the stock head unit because I like the 6-disc in dash, but I'm doubting it has the power I'm looking for. I'd be happy with something with sound comparable to the Bose 50w x 4 system in my old maxima.
