hmmmm thanks for the replys.... yeah its just i dont remember seeing any lines on the tweeter wires on my set of K2P..they indacate on the tweet itself..but i know the normal code is the wire with the line on it is negative...no i dont have a IASCA disc...no they are not ebay focals lol.....And actually iam very suprised of the sound though..Never Tryed any comps in the pollyglass line...But wanted a shallow mount mid in this install.... I figured they would be nowere close 2 my set of K2P in a previous install..Especially in the midbass output and clarity at high levels....But i must say very impressed, but I put alot of work into the doors Deadning and sealing.. running off a Focal 2.150
