for the past week not sure whts wrong i read that it could be the battery

are you getting long cranks when you start your car? slow cranking would indicate a low battery, but it may or may not cause the issues you are describing.

You can check your battery connections (make sure they are still tight). Maybe the lead to your amp is faulty and causes the radio to cut out.

that is very weird. I've seen very strange/random things happen with a bad grounding cable though. I'd re-check your stereo install and also be sure to check your grounds.
