Hello All,

I'm completely new to car stereo but I know I want to install a whole new system in my 2001 Coupe. I found the HU I want, Pioneer AVH-P4100DVD. I see my Mach460 system has 8 speakers. All of the component systems I find have 4 speakers. Do I need to install a component system in the front and in the back? Like two sets of Alpine Premier Components? Then do I need to get two 4 channel amps to power them? I also see 3 Way Component systems like the Focal 165 VR3. What should I do?

Thanks,
Giezr
