Anyone on here ever use the Alpine Type X they have been out for a while look to be one of the best out there. I am probably going to use 2 of the 12" which amp would you run? looking to stick with Alpine there too. and I have a brand new CDA-D857 still in the box I bought about 4 years ago I will be using. I like it because of it being a direct fit. LMK your opinions on this setup so far and any amp recommendations too. Thanks
