It starts everytime but it struggles a lot. Afterward, if i turn the car off it will start fine. It only struggles after it sits for a while. All i have is I/E and springs. I also have a 250 watt amp with 1 12 sub. I was thinking this might be it but i only run the radio when the car is one so it shouldnt run off the battery. Could it just be my battery? Any suggestions would be great thx.

 

could be your alternator going bad, just my .02 cents...

 

Get your battery and alternator checked out a autozone, they do it for free.
Batteries can go after a couple of years so it could just be about time to get a new one.
