Good luck.
I have solder for general plumbing stuff "safe flo lead free solder" and water soluble flux

should work right? or do i have to go on an adventure into homedepot right now, mask gloves, hand sanitizer

Plumbing solder would turn that board into a unusable junk. Make sure you have a good quality soldering iron with a fine tip made for soldering electrical PCB boards. Don't forget the solder wick or solder sucker. Amazon has all this stuff.

Anyone else here old enough to remember (and miss) going to Radio Shack, where the counter guys would do stuff like this for you, just because they were that geeky!

Silver bearing rosin core solder is very different than Silver Solder. Silver bearing rosin core solder is electrical solder with a very small amount of silver that melts at electrical solder temperatures with a regular soldering iron. Silver Solder is actually silver brazing and you need a torch to melt it. Steel gets a dull red before silver solder melts (800F or above depending on the alloy). Silver solder is sometimes call hard solder and they use it in high pressure home A/C systems to braze the copper line connections together. Silver solder comes in various amounts of silver and some of it is as hi as 40% to 70% depending on the application. It is quite expensive compared to silver bearing rosin core solder which is usually a mixture of several metals including lead, tin, some other metals and just a touch of silver.

You are fine to use silver bearing rosin core solder for your repair as long it is sold for electrical use.

I hope the iron you purchased has a finer tip. That sized tip is something I might use to splice larger wires together in a Jeep but would never get it near a precision solder job on a PCB board.

Update, the solder iron didnt come with other tips as i hoped but i was able to make do. Didnt touch the board with it at all. Got the old capacitor out and replaced with the new one. Super simple job trimmed and rtv-ed in place. Reassembled and plugged back into the jeep.

I started off low, radio started playing, then slowly cranked it. The volume went up all the way to 46, instead of cutting out at 30ish. 46 sounds a bit raspy but 40 was plenty loud with 1 speaker. I owe some people some beers!!

im working on making 2 small speaker boxes to wedge behind the roll bar, since i have 4 good speakers now

Very nice; congrats.

I'm by no means an expert, but I did a lot of stereo installs in jeeps at the shop I worked at, and on my own/ family rigs. There are so many subtle tips/ tricks to getting good sound out of a stereo system, and there is a HUGE difference to be had in quality components. Are your current speakers in the dash?

That said, don't be afraid to play around a bit with angle, box size, treble/ bass, etc.

You might find that less total sound but richer sounds better, or vice versa. And don't rule out a small amp and a speaker box or subsystem. Even a 'cheap' one can make a world of difference.

HTH and happy Jeepin'

That was the original plan, but now since I have an extra set of 5.25 speakers, I figured save money and use those.

I hooked all the speakers up, reinstalled the radio, dash and foam pad. Everything is almost put back together.

The rear speakers sounded a bit hollow (the new rockford fosgate) which I'm thinking is because theres no enclosure yet for them. But otherwise they all sounded great.

You could install the smaller speakers in the larger 6x9 enclosure by using a simple blockoff plate/board. Stuff the enclosure with that cotton type speaker stuffing and you would be good to go. You could watch for a set of 6x9s later. Can you send your extra 5.25 speakers back for a refund or are the extra speakers the old ones? Medium quality 6 x 9s will probably seound a lot better than the 5.25s.

6x9's are one of the best all-around speakers , IMHO. Especially a quality pair of 3 ways, but even a very good 2 way.
