99 Camry v6 with 2 12's dual subs powered by a 1000w hyfonics amp wired with a 1200 watt wiring kit that includes 6 gauge wire ,Scosche head unit also I wired in a toggle switch to connect/disconnect power to the sub so I don't have to find the setting in the head unit each time ... I've had this system working great every sense I put it in for the past 2 years till I had the car sit for 4-5 months this winter .. The cold weather finished off my factory Toyota battery so when I started driving it again recently i purchased a new battery that is equivalent to the oem battery ,same specs .. Subs worked fine for the first 3 days then the next morning on my way to class the subs quit working so I toggled it off and then back on and they worked for about 20 seconds then quit again ... It will work sometimes for longer or shorter befor they quit again and wont start again till I toggle the amp off and back on ... Haven't changed anything but the battery and it is same as the previous one that worked for the past 2 years .. I thought the amp was cranked up to high so i tried turning the settings in the amp down and it still cuts off ... Also tried a different set of subs and it does the same thing. .. Also I checked the amp when it's working and while it cuts off and the amp is NOT going into safe mode or anything like that .. Power light is constantly lit on amp when the subs are working and after they cut out . Help thanks
