I have had all of mine replaced with Hertz mille pro, alpine amps, and custom sub box with an Alpine sub. The H8 is not a good choice as it can only accept 4 inputs. The bit one however can accept 8 so you can keep your chimes, fade control, cross traffic alert etc. The rear speaker input is required to keep some of these alerts. The only speaker I did not change is the center channel. Mine is a vert so I do not have the other two speakers in the rear deck lid either. I am currently using an Alpine PDX-V9 5 channel amp for the whole system and it sounds great but I am going to change it out to a PDX-M12 and a PDX-F6. That being said you could use a stacked configuration with a PDX-V9 and PDX-F6/F4 and you would have 9 channels available on for the sub(500W) and 8 more for everything else. BTW I originally installed the H8 and discovered I had no more cross traffic alert or back up warnings of any kind.
