My friend gave me an Infinity 1230 watt 12" subwoofer. He said that it had a bad wire connection between the input and the cone of the speaker...... Can this be fixed easily??? What do you reccomend???
It can be fixed, but not real easy. You need at least a 25 watt soldering iron, and some solder of course. Let the iron heat all the way up. Then "tin" each half of the broken leads. Now on the side that goes to the voice coil, you want to be VERY CAREFUL AND NOT OVER HEAT IT!!!!!! Once both leads are tinned with solder, using forceps and some help from a buddy, hold the 2 leads next to each other and solder them together without any additional solder. Then you are done. I have done this myself several times over the years and had pretty good results from it. If the tensile lead (the wire you are refering to) is broken at the cone, it might be next to impossible to do this, in that case it would be best just to see how much it would be to have the speaker reconed at the factory, then it would be a brand new one for little money
I personally do not know much about car audio at all... I can see where the wire is just barely still together and that is right before it gets to the end of the wire where is it connected to the bracket right next to the cone..... As you can probably tell by the way i talk i do not know much about what i am saying but i appreciate the help ... I think my brother can help me because he has always been into electronics and is now a sattelite dish installer.....
If the tensile lead is broken next to the terminal that connects the wires to the speaker, it should be an easy fix! Any one who has a decent chlue on how to solder wires should be able to help you out.........
actually from my experience, soldering these wires back together will only cause them to fall apart again a few days later. the only way i have been successful on fixing these connections is to cut them from the terminals and crimp splicing the speaker wires directly to the tinsel leads. solder is not elastic enough to handle the constant movement of the tinsel leads. it will eventually break from all the movement.
You are right ducttape....... I should have made it more clear on the soldering technique, when soldering the tensile leads back together, be sure and only solder at a localized area, NOT the entire lead! I have made many repairs on speakers using this method and most all performed for a long time after the repair. However, with todays new high excurion speakers this may not be a reliable fix. Most of the ones I repaierd had an xmax of only 10 mm or so, that was years ago!
