the 16v already comes with a cheap set of componants as standard. the mid/bass is in the door and the tweeter on the dash. For the companants you have bought, there will be one input into the crossover and two coming out-one being he bass/mid which goes in the door and the tweeter on the dash. As they are a cheap standard wiring so all that happens is the same wire goes to both and it is just split along the cable. To cut a long story short, they are both the same as the tweeter has a capacitor on it! Mine work fine!
