What is it with people and bass lol, Honestly i have had 2 set ups in my car and i love both of them equally
Alpine CDE9886 headunit (direct ipod, usb, mp3,tuner, optional bluetooth)
Alpine Type R 6.5inch Splits front
Alpine Type R 6.5inch Coaxials
Alpine MRP F600 4 channel amp 4x100watts rms
Also using same headunit but replace speakers with Focal polyglass splits and coax's
went from focals to alpine as they were cheaper but still gave the same result and found them crystal clear and no need for a sub of any description
The alpine system cost me a total of $1000, i was able to fit it all myself and i did work for JB HI FI in car audio, its a real impressive system for the money outlayed
