i ordered an lightning audio capacitor distrubution block that accepts 1/0ga in, two 4ga out, and two 8ga out. when it arrived in the mail, i could barely fit in 0/1ga but it fit 2ga perfectly fine. as for the 4ga out holes, not even close. biggest size that i could fit were 8ga. and the 8ga holes were basically speaker wire size //content.invisioncic.com/y282845/emoticons/uhoh.gif.c07307dd22ee7e63e22fc8e9c614d1fd.gif
idk if lightning audio overrates their equipment but becareful when choosing lighting audio installation products cause their 4ga can mean 8ga in reality and so on.
