What the hell are these little wires for??? (93 lx)

The adapter kit i got dosn't match up with the wires in my car. one plug does and thats the one with the power, acc. and ground wires, the other plug which is the same shape and has 8 wires also is far diffrent than the other one that came out of the back of the OEM deck. the one that came out of there, that one has 9 very small guage wires(prob. 22ga.), one of which has no insulation around it and they all go into a smaller more square shaped connecter.

i have the ground, acc. and 12v. wires hooked up and the radio comes on and there is power in the output wires.

Now, i know the car has 6 speakers so why are there only 8 wires? and why is it that when i try to hook the radio wires up to the the little ones i assumed were going to the speakers nothing happens?

i really only plan on using the four speakers, and not the ones in the dash so im not worried about them. the other plug that came with the kit looks like it would fit up farther kinda behind where the radio goes and it looks like the wires that come out of that are the same color and patter as the ones going into the speakers when i take them out.

So my main question is where the hell do i put the other plug and what the hell are those little wires for?

how do i bypass it then? can i use the harness i have now?

so where is the amp? because i think im going to take the wires that come out and hook them up instead of buying something else. if the allcome out of the amp then i should be able to just take them out and hook them up and not have to run new ones right?
