Reply to Skipping Needle from subwoofer

Hey so i'm pretty new to timecode vinyl but i really plan on sticking with it. Im curious to know if theres anything i can do about my needle skiping because of the subwoofer? ive played a few events with these turntables and i keep encountering this problem. is it my cheap needles? i have two stanton t80's and a serato sl1. would getting some fresh new needles help? i put a lot weight on the needle and that helps a bit.
