Current set up is:
Car: g35 Sedan Base model. (no Bose)
6.5 speakers are all alpine.(4)
My question to all of you is, at semi higher volume, i get distortion. Do you think it's due to me not having an amplifier on the speakers, or have the stock headunit? i can't replace the headunit because it's all integrated into the ac controls and such. I'm quite unhappy with the sound quality. I was thinking of replacing the 6.5's again with maybe something different to see if that would fix it. However, i'm not sure that will solve the issue. any input is appreciated.
