Hi all, so I have a 15' kicker sub and 1000 watt panasonic amp. Now everything was working properly having no issues what so ever but in the last week for some reason the sub will not work at all from the moment I turn the car on but after roughly 30 minutes or so the sub will start pumping out the beats and be working without a problem. However once the car is turned off, it's a matter of rinse and repeat. The amp does have power to it and the led shows that it does, but still nothing happens with the sub until 30 minutes in. Now as you can see that is obviously a great annoyance unless I'm planning a trip larger then that time frame. So my question to you all is, have any of you experienced this before hand at all, and if so, how did you rectify it?
