Turning Creative Inspire P5800 into a car sub

Hello the speakers died completely so I went ahead and tried and add my findings here in case anyone try to do the same and land on this thread through internet search.

I removed the circuits and the back ports from the woofer cabin and closed with adhesive vinyl all but one hole to get the cable through.

I connected the subwoofer to the coaxial outputs of the pioneer but nothing happened. I tried a lot of combinations in the options about this in the settings but nothing changed, the subwoofer didn't got any power no matter what I tried.

I though that maybe this specific speaker need something special that was on that board, but then I tested it on the coaxial out of a mini hifi I have at home and it worked.

So without knowing what was the problem I decided to take the harder path and find the outputs from the main connection of the car stereo which I wanted to avoid since it have like 10 cables in 1.

This did the trick, it works like a charm. The only problem is that the speaker is not really protected (the subwoofers that are intended for car use have a metal grill over the speaker to protect it when you load the car for example).
