I pulled the amp out of the car and wanted to know which components might need to be reflowed. Mac sub mentioned this to me in a previous post. The amp responds to temperature conditions and bumps in the road. Also, do you have a special way of soldering the components or dismantling the amp for easy access to the components?

Thank for your help

Heat up the solder & add a bit of new solder at the same. It's not an exact science, but the bigger the soldered joint then the more likely it is that there's an air pocket or just corosion inside the joint. You'll know when you find one as you'll hear air escaping (like a small fart) when you heat it up.
Extracting the PCB is easy, just a few screws which are all obvious.

I flowed about 50% of the components on the power board and also both flex strips and the main connector. Unloaded current draw at 12v is around 350mA. During fault the current would drop to 280mA,hense the amp turn off during regular operation in the car. Thanks for all your help!!!

You wouldn't believe how many amps I've saved from the scrap heap doing just that!
