[QUOTE="DRBOOM, post: 8670550, member: 676005"] The four gauge power wiring should be more than adequate. I would also suggest to use a multimeter to get a reading of your battery condition as well as I don't know where you are and that cold weather also plays a toll on the battery regardless of their age mate. In theory, the car only needs 2 volts to start so if you are experiencing this issue, use a multimeter to probe on the terminals and let somebody start your car and if the voltage drops significantly, then it could be your battery issue here as 400 watts is not enough juice to cause this issue for you. Another factor we do not know is how often you drive your car as that can also be an issue if you don't drive it too often. I have a stock battery with 1200watts RMS system being run off a stock battery. I do drive daily , so my battery is kept charged by the alternator , like 200km / 124.2 miles per week and I travel to my remote work which is 400km / (248.5miles ) away every 6 weeks. :fro: [/QUOTE]
