hey guys , so today i was fixing my audio in my car and turned the car on and off while i was doing it everything was all good. Then when i came back 5-6 hours later i couldnt unlock my car i assumed the key battery died i opened the boot and saw that my amp was on . then i realised battery died. i called my mate to help me out he has a civic eg tried jump starting it, didnt work. topped up the water as it was empty. After that i tried my mum camry left for a good 5-10 mins while trying to turn it on in between still nothing. it just makes a clicking sound now. inside lights turn on , headlights dont work but my high beams work ( i have HIDs if that counts. no idea what the problem is , would it be the battery? alternator? or i need a stronger car to jump start? any input will do. thanks guys
