amp problems

[fisher]

hey guys,

update on my cold weather starts noise problem. i messed with the wiring, and found that if i switched the speakers (left->right right->left) the noise moves from the right side speakers to the left (it's a nasty interference noise) but if i switch the rcas it stays put, so i'm guessing i've narrowed the problem the amp itself (rf punch 60ix running fanatic components). i was hoping the problem was the crossovers (mounted in the door panels, was hoping they were just too cold) but it looks as if it's the amp. it goes away when it warms up, but that takes alot of time cuz it's so cold and when i'm out of my truck for 15 minutes it comes back. any ideas or should i just start shopping for a new amp?

thanks in advance,

~erik

take it in to be fixed sounds like it might be a cold solder joint its about all you can do or get a new one

Bingo, you have a cold solder joint somewhere. Simple fix!

not that easy of a fix. http://www.termpro.com/ubb/smile.gif i had the electronics guy here at work resolder all the joints, and now it's more constant (doesn't have to get cold to make the noise, it always makes the noise!). ouch. oh well, i found a replacment amp at a great price.

thanks guys.

How thourough was he when he re-soldered it. Sometimes it takes a fine tooth comb to locate a bad connection. You can't always tell by looking at them. Even loose screws which hold the pc board to the chassis of the amp can cause grounding problems. Heck there could even be a small crack on the board. Sorry Dukk, I know where you were going with that http://www.termpro.com/ubb/smile.gif . Sounds like he re-soldered the broken connection if it's more constant, but it could be a lifted/cracked trace and he un-did it permanently.
I'd love to have a crack at it!

Could also be a condensation problem. Corrosion will tell the tale.<CENTER>

You'd think the tech. would have found that when re-soldering.

By the way, were you two at the same party? It looks like you both got home at the same time.
