Power Inputs came off board MTX 1501d

i've been having a problem with my subs just clicking off. i thought "hey maybe that screw holding the GND wire is loose again...". no big deal. so i check it. good. so i then check the fuse holder. good. battery. good. so i start over. as i wiggle the power wires i see the whole shit moving.. so immediately pull the fuse. that was yesterday.

today at lunch... pull that amp and take it apart. when i get it open, i was able to just pick up the power input off of the board.

i should be able to just solder it back on, correct? it didn't get a chance to fck anything else up because the amp still worked, it'd just click of over a bump or something. it was mounted on the back of my box along with the 404 so i don't think that's the reason. the 404 is working fine.

me wires come out at a weird angle and maybe they had some stress on it. that combined with the vibration from the sub might be why this happened. this ever happen with anyone else? i thought it was crazy that all the solder just broke.

19min bump before i head out. i'll try and take some pics. i'm gonna solder it back on. it should be fine me thinks.

pics first, yes soldering will do the job, as thats the way it was previously, just try to make it as strong as possible.

1st off, i'm a n00b at soldering //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

...so i got it all cleaned up and now i'm trying to re-solder it. i CAN NOT get the solder to go into the gap between the board and the piece. also i cant make it stick. when it dries or whatever it just falls off...

wtf how do i do this?

oh, and no pics ftl. sorry //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

wat you should do is practice on something thats not important till you get to where you can control it better thats about all i can tell you other than make sure its very very clean

using flux? or resin core solder?

resin core

 

[edzy 10+ year member]

well, either the part is not clean, the iron is too hot and burning off the flux. Use a sand paper to clean the parts, using the pump will remove the solder, but not clean it. It needs to be clean metal for the new solder to stick.

im guessing the connections just broke off?

on the 20.1 if you break the power connection the amp is fuxed.....

but for real all was good. it would come on and still beat. hit a bump and *clicky* nothing //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

turn HU off/on and bumpage continues

dont try to make a connection with the solder itself. the component leg must be inserted into the hole in the board.

LOL... you have to have an extremely hot iron (over 1000 degrees) like we have here at dB-r for that soldering.... What we do, is drill a hole through the PCB and the power connector, tap it, put a bolt in it (short bolt, fine thread is best) and then solder over it with our torch, which is over 2000 degrees at the tip of the flame... You have to be "careful" at how you do it or you will "fux" up the board bad...

 

[dB-r 10+ year member]

No a IA 20.1 is not "fuxed" if you break off the power connector, it can be fixed...

this iron and this solder.

 

[dB-r 10+ year member]

LOL, no you need a good iron like 50-60 watt like Hakko 936 or something at least that good and regular leaded solder... leadfree solder sux...
