Ok, i bridged my amp ther other day, and it was all fine, then it stopped working the other day, so i took the wires out and messed around a bit.. and the way it works now is both + to the - on one side, and both - to the - on the other... instead of -s to the -s on one side, and +s to +s on the other channel... anyone know what this is?

when you bridge some amps it internally connects the + of one channel to the - of the other. this causes 2x the voltage and thus 2x the current to be supplied to the speakers. the way you're connecting it will work but only supply one channels power to the speakers. if it works like this but not hooked up like normal, you probably blew the other channel. Try hooking it up non bridged and see if both channels work.
based on what your other thread said, when you replied to me, here is my diagnosis:
you have an amp with multiple channels that is bridgeable. You then have either got a dual 4 or 1 single 4 ohm subs, and you wired it(them) down to 2ohms. 99.99% of the time a bridgeable multi-channel amp is only stable down to 4-ohms. You are asking far too much from that amp and it is going into protect mode. As far as I can see, from the information provided, that is the issue you are having.
On the other hand....you have other fingers.

Ok, so if i wired it back up normally, not bridged, do you think everything would be fine? and im pretty sure they are single 4 ohm subs, and the amp is 2 channel, rockford fosgate punch 100.2 ... my friend does alot of car audio stuff, and he said that it would take the amp to a 2 ohm load, and i would get a 300% gain on it... could that be pulling too much? would it just be fine wired normal? thanks again to all..

you're friend does a lot of car audio....the wrong way apparently.... wiring to 2 ohms would not give you a 300% increase in power. the amp is only stable to 4 ohms when bridged. period..
what subs are they again?

Well... his exact words were 300% "gain" .... so idk if that makes a difference.. but yea... lol, anyway, the subs are 12" MTX road thunder 2s
"Hondas are like tampons, every pussy has one!!!"
you are trying to bridge a pair of 4 ohm single coil subs to a 2 channel amp(im pretty sure those subs also come in 8 ohm single coils also, if im thinking correctly, but 4 is far more common), which means, your wiring could go 2 ways.... 2 ohms, which would put your amp into protect mode or turn it off as it is doing now, or 8 ohms which would just make them uber quiet by giving them half the power the amp can put out.
either run each sub off each channel, or bridge it up to 8 ohms, and in both cases not give them much power... or save some cash and upgrade all your old stuff
any pics of that amp by any chance?

No, I think you blew one channel. By hooking it up normally you can check to see if it's blown or not.
if the + of one channel is connected internally to the - of the other one, the way you have it hooked up now is the same as running both speakers off of one channel. You're not using the other one at and it probably won't work with it unbridged either.
