Hey guys I have never used 8's ported. I am going to build a box for 2 RE RE 8's off an alpine pdx2.150 amp. I am thinking about ported and the website says .5 at 35hz. Should I go any bigger or any smaller than this. I also would like to know about how much port area I need say like a 4" aeroport or whatever the case may be.
