sound bar questions (for pros or anyone else)

like the title sez I have questions bout my soundbar. I have pretty much rebuilt the original soundbar. It had 4" pioneers in it and I put 6.5" JBL Gtos in it. I did it right I bought mdf speaker rings mounted those to the soundbar, glassed it, body filled it, used dynamat tape in the speaker cavities, and stuffed it will poylfil, mounted the speakers up and went to install it.

Heres my questions:

does anyone have any idea which of the speaker wires are positive and negative?? One is blue with a white stripe, one is blue with a brown stripe and the other colors I cant recall right now.

I did temporarily wire it up and put the soundbar back in but it has almost no bass output. I mean the 4x6 pioneers have more bass. Im guessing they are not getting enough power from the pioneer head unit, but I thought id have more output than I do. Ive messed around with the stereo and I just cant get any bass out of those speakers. I was really counting on the 6.5's as I wasn't really wanting to spend the money or the space installing subs. I suppose having them wired to the plug wrong could have a effect on it as they would be out of phase or just wired backwards which leads me to the 1st question posted above.

Ive messed with stereos for a long time and this is the first time Ive ran into something like this. Any help is appreciated.

If it's the original Soundbar

A is positive & B is negative as marked on harness end, I used a AA battery to determine this.

Worst case scenario look at the cones when wired to see if they fire in or out

Okay dudes and dudettes. I have installed my sound bar back into my jeep and connected all the wires. Now I've got popping noises in my speakers. Now for the rub it only does it on certain songs that have a heavy bass beat I.e. The Band song the weight. That song does it really bad and little Texas kick a little. Usually I wouldn't even name songs as it would mostly be irrelevant, but its relevant here because those two songs are two that it does it the worst. I took an old speaker out with me to test polarity and it seems the polarity is correct. I've wired it two different times and two different ways.

Its worth mentioning that the wires in the soundbar were already pretty worn so I stripped all the soundbar wiring out and wired t with brand new wiring. I soldered the connections at the speakers and made sure those connections were solid and when I went to wire it to the original jeep wiring I used crimp caps and insulated with black electrical tape. I also cut the original plugs off: I know I know bad move on my part.

Any ideason what's going on????

sounds like a grounding issue with either you amp or head unit, also where you drawing your power from? and before the last post i was gonna say you did all that work to the speakers and didnt rewire.

ROFL no I rewired them, boy that woulda sucked wouldn't it. Its just the head unit powering them right now. I think I fixed it though. The factory plug had four wires coming into it. I assumed positive and negative and positive and negative, so I hooked two positives and two negatives up to each speaker. If that is clear as mud, I'll try to clarify. Two 6.5 speakers each with pos and negative, so I took the two positive 6.5 inch speaker wires and wired them to what I thought were two positive factory wires capped them off and did the same with all the negatives. But this evening I went out and tried something else. I just used two of the factory wires. 1 pos and 1 neg. That fixed the popping issue but now I don't have left and right balance. Oh well at least for now the speakers aren't popping on every bass note.

BTW when I put the balance in the middle it sounds like both speakers are wired backwards or something, out of phase or somwething .
