Default Stereo - speaker wiring problem

Had a new fusion system installed. 4 speakers - two in bow and two in Ttop.

The front two in particular, which face each other, have sounded "odd" to me. I was worried they might be out of phase (heard of that) so was doing some research on how to determine if so. Ran across two speaker tests which check left vs right and center.

When I play what the website says is left, only the top speakers play. When I play what is supposed to be right the front speakers play. And when I play center or all, they all play.

I am assuming this could definitely be why I am not happy with how this sounds? I did not do the wiring. Is it as simple as tracing the wires from the fusion wire assembly, which appear labeled, and see if I can find how this is crossed up? If they are not labeled coming from the speaker there may not be a way to tell which is which but suppose I could just switch a left for right and do the test again right?

Yes .
You have the zones wired as Left and Right.
Zone one (or 2) should be front and zone 2 (or 1)should be top.
Easily fixed at the head unit.
You can use a 9 volt DC battery to test speaker locations. Just connect one speaker wire to the negative wire and momentarily flick the other to the positive. The speaker will sound. If someone can watch the suspension cone, they will see it jump forward or backwards. Use this method to check the phase of the speakers.
It doesn't matter which way the cone moves, as long as all do the same.

sounds like idiots wired it. you don't even have zone control which is the best part of the fusion.

the back of the fusion will have zone 1 left, zone 1 right, zone 2 left, zone 2 right.

disconnect all 4 speakers. hook one up at a time to the same stereo wires. (IE just grab zone 1 left, and touch to all 4 speakers one at a time, figure out which speaker wire is which speaker,, label them as you test)

once you have all 4 speaker wires labled at the deck. connect all 4 back to fusion correctly. just pick zone 1 as bow and 2 as T top. but it doesn't matter which is which. and obviously left to left right to right.

once you are done you should be able to turn the zone volume up and down on each zone and also balance left to right. and all 4 should be correct.

also in the mean time. open up the 4 speakers. they will be labeled pos and neg on the speaker posts. the speaker wires will either be labled or have a line down one side. just match pos on speaker to pos on deck. for all 4. so they are all in phase.

if you can, put some wedges or similar under the speakers at the bow (to angle them towatd the stern, not up or down)..... speakers should never directly face each other. for a good explanation as to why, find someone who wins car stereo competitions (no, thats not me).. it has something to do with acoustic standing waves and sounding "muddy"....

Thanks, all good now guys. Installer did a nice job, he did it on the side at night and this was probably done late night, just switched up two wires.

This is only my opinion, but unless it's a yacht/large sportie with multiple areas, the zone control really doesn't mean anything. Maybe I'm missing something, but I've never used my zone control once on my 24 cc

On smaller boats, the zone control is the same as a fade control on a car stereo.
You set up the 2 volume levels or zones for 'surround' sound front and rear balance, then lock them together so that the one volume control, adjusts both sets of speakers, with separate volume levels.
You probably are using your radio like that or you have your 4 speakers wired incorrectly to just one zone.
