90 century limited rear deck speakers

[Wazaam]

well my right rear deck speaker went out last week so i tried to replace it. the old speaker had a recieving plug that hooked up to a light blue/yellow wire and a dark blue/yellow wire that had a plug on aswell. i have no earthly idea which one is + or - the left side has a brown/yellow wire and a striped brown/yellow wire, i was goin to replace those too. the new speakers i bought have a red and black + - reciever for bare wires. ive thus cut off the plugs on both wire sets and tried to put them on the same way they were on the old ones. ive now zapped my battery to oblivion and need help

I have never heard of a car radio speaker wire with enough juice to fry a battery. Have you checked your fuses? Is this thing hooked to an amp? If it got your battery your can probally guess that the alternator brushes are singed off too. First check the fuses and most if not all speakers can give a rats ass about the polarity. But if yours is like one I have never seen there are two thing I would try. First pull the radio from the dash: sometimes the wires are labled and other times there will be a map legend of the wires on the radio itself. If that doesn't pan out then after removing the speaker wires you fixed and taping each off, each by themselves, get a testing light (looks like a screw driver with a bulb at the handel end and an aligator clip suspended by a wire), replace your fuses, fix the alternator, battery, and what ever else has been fried and test each speaker wire for juice while the radio is on. Good luck.

ok i figured why my battery went dead was one of the wires was cracked and was touching the bracket on the speaker. now my new problem is with the speaker that was messed up in the first place.

the right speaker wasnt dead but it was fuzzy and not so great. new speakers same problem. better speakers so i dont mind the whole issue but id still like to fix the problem... my first assumtion was faulty wires seeing as less sparks come from those wires when brisked against the above said brackets. if all else fails ill just rip it all out and do it myself instead of the way my grandfather did it(cheaply).

It might be the radio itself. Try hooking up the speakers (new and old , one at a time) to the left speaker wires and see if it/they still crackel. If it does then you know the problem. If it doesn't pull the radio from the dash and test the speakers again at the back of the radio on the same right rear speaker wires. If the new speakers both still crackel it's a bad reciever if they don't then it's in the wiring under the carpet to the speakers. If it turns out to be the radio, you have a few options, you can hook the rear speaker wire to the right front or one of the good three channels left of your choice and tape off the back right wires. Or get a new reciever.
