Heres the setup i want to achieve

2x10 Alpine type x subwoofers
2sets of Alpine Type x Pro 6 1/2
2sets of Alpine Type x Pro 5 1/4
2xPDX1.1000 or PDX M12
2xPDX1.100 or PDX F4

The headunit is a Pioneer Z110bt

This system will be going into a Mazda 3 hatchback 06

Custom doors will be molded aswell as the trunk space.

All together thats about 2800 Watts RMS

Question is what size alternator should i get for my new Kinetix 2400 or 2x1400? Is a 170Amp HO at 14.4 enough?

Thanks
