Wiring diagrams. I'm not sure if all models come with the kick plate amp.
I wanted base but since i got a 16 they upgraded me to sync 3 which is apparently the shaker system without the sub.
As for Alpines, great choice. I used to punish my alpine subs and never blew. The doors however i ran too hard.
I had my doors around 120w a piece if not more, and it was supposed to be 100/110. Subs i had wired in series on a monoblock 2400, which i kept between 1200-1400.
Not a comp build by any means but it was a loud '12 focus.
