Hi all,

After many posts about my audio quality and the bass that comes out of my new jvc cs-j620x is terrible, many of you suggested to go for a new aftermarket headunit.

So here I am, I am going to buy a pioneer FH-X731BT.
This particular HU has 6 jacks in the back except from the regular universal plugs.

After I saw the specs the 2 jacks on top are for middles, the 2 jacks in middle are for highs and the last 2 for sub.

But I have never done this kind of swap in the past and I don't know how to use these jacks. There are 2 jacks for each output(look picture below). So I assume the one is negative and the other the positive? Or in every jack I plug only one speaker?
If it's positive-negative, how I am gonna plug 2 speakers ? In parallel?
But the HU has built in settings that I can tune each speaker alone. Meaning Front left front right etc.

If it's in parallel connection how the stereo will know which speaker in particular I want to tune?

I hope you understand what I am saying.

Also anyone who has the wiring diagram?

Those are the preouts for connecting an amp. Not used if wiring speakers direct to HU.

Are you sure? Because I think they are for directly plug speakers. At least that's what I heard in a video
