I bought it directly from the authorized US dealer from their website, I trust the parts should be OEM quality parts. I agree your harness would definitely come handy in my case. I am pretty confident I got the crossover wired correctly as there are lables on it. And I soldered the connection. However, my wiring fell short, I had to extend it by strip and twist it to other piece and black taped. I don't think that should have any problem.

For the speaker wiring, since there is no label of +/- on it. Could you help clarify something, would be greatly appreciated. I used the larger clip as positive end, and smaller clip as negative, is that correct?

I had to strip it down to bare circuit to get it fit in the door. I used velcro to mount at upper back end corner of the car.

Yes

I've also heard these speakers, and I know that when everything is properly connected, this gear should sound great.

Any suggestion what I can do at this point? Should I bring this to a shop near by?
