first of all to the people saying why not let him go rear fill.. simply put, because i am his FRIEND. my system gets DAMMN loud without rear fill, sounds very nice, and oh yea, i dont sit in the bacc.//content.invisioncic.com/y282845/emoticons/rolleyes.gif.c1fef805e9d1464d377451cd5bc18bfb.gif second, if he wants to go rear fill, i am going to stress to him to just go coaxials in the bacc because he is thinking if he gets hexes in the front hes going to get them in the bacc... and i really think thats a DAMMN waste cuz then he could spend that 600 on a BOMB *** rainbow set or something like that.. or iridiums or something. third, the reason im asking about the "internet brands" is because in the past year of being a member on this board, i am well under the impression that they can perform just as great as the major name brands but at a fraction of the price.. correct me if im wrong... you guys love your hexes yea.. and im sure he would too. im just trying to get him a better deal and something that he could love MORE like 3.5max6spd mentioned above.... something i wish i could be doing if i got something better than infinity perfects. (don't get me wrong, i've tweaked them to sound optimal)
