I have a 2.0L 4 cyl. Standard 626 and I Recently just drove from Ottawa, Ontario To Barrie, Ontario (roughly 5 hours) I never had battery issues with it before. The battery is completely dead and I had no problem starting it two days ago so its only really been sitting for 36 hours roughly. I am not sure what it could be. Nothing comes on, not the dome light, trunk lights, door lights, dash lights when you turn the key. Just nothing happens. The only thing I can think of that would drain my battery  is my radio because when I been driving every time my radio is on and I hit the brakes the speakers crack or go out and then come back on when the brakes are tapped/held again(Not usually in any order, could be 1 tap could be ten taps). Anyways When I arrived in Barrie On the 2nd I noticed that when I held my brakes my radio complete went dead there was nothing coming from the radio all the speakers went dead and usually the only speakers that went out were the rear ones (The radio is completely stock as well). I am probably going to charge my battery tomorrow after I disconnect the radio and hopefully that will make things good for the time being.. Anyone have any ideas what else I can do or try?
