OK guys Im not in this section too often but this is really bugging me and I need some serious help. Im not new to installing stereos in cars so let me explain this and then if someone can answer me then thanx.

Basically, Im installing a head unit in my 93 honda civic DX. Now, if im not mistakin, there should be a total of 12 wires from my car to install to the head unit: 8 are for the 4 speakers, 4 positive and 4 negative, and then the last 4 are for power, ground, ant. and acc. Now for some reason I only have 10 wires. 4 of the 10 are separate from the other 6 so I know these 4 are for the power, ground, ect. The other 6 are speakers, but my front 2 speakers share the same set of wires.

What I mean by this is as follows:
My front left and front right speakers need to be wired thru 2 wires, a positive and negative for each. The wires are gray with a black stripe and blue with a green stripe. The only thing is, both the left and the right speakers have these same wires.

How would I wire up the head unit when both my front speakers share the same 2 wires? Would I just splice the gray and blue wires and connect them to each of the wires off the head unit? Help please....
