You should try this first you start the car and give accelerate for 3 to 5 times gently then put 1st gear and slowly realize accelerator. and if your battery is stacking then go to the mechanic..
thanks for asking this question for us. well I think For the 2 500 watt speakers you need a 1000 watt stereo amp that would give you 500 watts per speaker/side is best amplifier for you it's very lousy..
thanks for sharing this for us. I'm using a 900 watt rms amp with two 400 watt rms subs. 1000 isn't much more than what I'm using, so you should be fine. I didn't upgrade anything.so you also try to quite less volt..
