I still have an old school Alpine head unit with an Alpine amp for my Memphis sub and an Alpine amp for my JBL component door speakers and Memphis rears The rear soeakers are more for "fill" and actuallly over power the front which affects the imaging. Since I have made the stereo upgrades I rarely listen to it lol. I prefer the sound of my engine and exhaust lol. Good luck making your decision and let us know what you decide
