hello, my friends and i are puttin in my system this week and i had one of my friends build a box that can hold 2 12" subwoofers in it. My question is he didn't put terminal caps for the wires on the other side he just said to drill 2 holes and run it like that. My other friend said i should get terminal caps to hook the wires up to and run it w/ terminal caps. I was wondering if terminal caps made a difference or if i can just run it without them?? Thanx and please respond as quickly as possible!!!
