Need to find out which is the proper speaker wires for hook up yellow to tweeter or sub? And striped one is positive or negative?

Yellow is positive, yellow/black is negative.

The four speakers are split into two groups left and right. You connect the positive terminal on the upper left speaker to the positive terminal on on the bottom left speaker. Then repeat process connecting negative to negative on the same two left speakers. Then connect one wire from the upper left positive to the positive connector on the jack that is marked 4ohm LEFT on the plate attached to the rear of the speaker cab. The do the same connecting a wire from the negative terminal to the negative terminal on the same left jack. Now repeat the process on the right side in exactly the same way this time connecting to the 4ohm RIGHT jack. The switch that is in-between the two jacks can be set for either channel or for both together for stereo at 8 ohms HOPE THIS HELPS

Sub outs needs an active speaker.

An active speaker have a built in amplifier and preamplifier.

For a passive speaker it needs an amplifier.

Peavey color indicates that Blue is Negative And Yellow Is Positive, so Yellow goes to + Speaker Terminal.

black and red will goto 1 speaker. and blue/yellow to the other. typically red and yellow are + and black and blue are -. the crossover board might tell you which is which where they solder to it. but i'm pretty sure the black/red goto woofer. try hooking up both to woofer and listen to it. 1 way is going to sound horribly wrong lol. that will mean you hooked up the tweeter leads to the woofer. but DO NOT HOOK UP WOOFER LEADS TO TWEETER. thats why i say to do it on woofer.

Usually the colors you will find are red and black pair and yellow and white... USUALLY the red/blk pair go to the tweeter horn with red going to the + lead of the horn drivers. Usually the yellow/white pair go to the woofer with the white going to the + lead of the woofer in Peavey speakers... HOWEVER you never know if someone has rewired the cabinet so going by colors is NOT the best way to go... This should have the "soundgard" circuit in it and the lead that goes throught the lamp and resistor that is NOT connected to the inout jack is the TWEETER + lead. The pair that connects to the inout jack DIRECTELY is the woofer leads and the TIP connection of a 1/4 inch jack is the + woofer lead. Verifying these connections is the best method.

"terribly owful " is not a descripption we can really understand. You need to describe whether the probllem is with the bass or treble speaker... lows/highs... The only suggestion we can give is to open the unit. You will need a LONG phillips screwdriver and remove all the screws in wells around the edges from the back and then gently separate the shell. Inspect for loose wiring. You don
t mention if you are using this as bi-amped or not which we need to know. This unit has the soundguard protection of the tweeter which consists of an automotive type lamp and a polyfuse. I would open the unit and see if there is a problem with the connections or possiblly a socket problem with the lamp as that would disturb the tweeter level. If you are bi-ampong this, then verify that swapping the speakers the problem is the speaker and NOT the cable or amp... Also verify the switch on the back of the speaker is properly set.

Way to find out: The minus speaker leads go to ground at the amp and therefore are electricaally connected together... just use an ohmmeter to find which two wires are tied together and connect those to the minus leads of the speakers.

The positive and negative jacks are for selecting correct phasing.

If you did as you say, one speaker cone would move out and the other would go back. This is NOT what you want. Connect minuses and plusses when paralleling.

Do make sure you go no lower than the spec impedance of the speakers... If you have two 8 ohm speakers in parallel that is 4 ohms which is MINIMUM impedance allowed by a lot of powered mixers.
