no, like i think its hooked up to the power cause i can keep it on for a really long time, its just when it get's turned up louder it turns off, i've kept it on just with the headlights for about 2 hrs before so its getting power. And when the cars on the low bass shuts it off at a certain volume, but, it doesnt alwayz shut it off. like i can listen to a song and when the low bass hits it shuts off and i turn it down like 4 notches and its fine then i can turn it up and sometimes it will stay on, then sometimes it will just shut off again. i usually listen to it at about 28/35 (volume) and if it shuts off at 28 i turn it down to about 25 and it will work. and then i can turn it back up and sometimes it will stay on. Never does the same thing. so it's kinda various if it wants to stay on then it will, but if not my HU and Amp shut off then turn on like 2 seconds later. and when low bass hits my Cap drops to about 12.22. But, im gonna try to take my ground out of its spot now and then and re-ground it in a better, shorter spot. but what do u think bout all that stuff?
