Which battery setup?

[wafsman 10+ year member]

I am needing to upgrade my battery, but would like to know which setup is better since they cost roughly the same amount. First I will be running an American Pro VS-1407 and a Sundown SAE-1200Dv2. I plan to upgrade my starting battery. So would it be better for the car and the stereo to run a Duralast Gold up front and a Kinetik HC800 in the back OR to run only a Kinetik HC1800?

You also have to account for what the car needs.

How do I choose the correct Kinetik Power Cell for my application?

"Kinetik makes choosing a Kinetik Power Cell simple. We made our model numbers equal to the wattage needed for your vehicle. For peak performance and the maximum lifespan of all electrical equipment in your car, simply add up the total wattage needed including all amplifiers, lights, winches, video and all other electronics and make sure the model numbers add up the same amount. Allow from 800 to 1200 watts to run the vehicle depending on the electrical requirements if you are replacing the under hood battery also. For example; a car with a stock 90 amp alternator can use up to 1200 watts to run the factory equipment already in the vehicle (90 amps x 13.6 volts = 1224 watts). Remember, there is a reason the factory put that size alternator in the vehicle in the first place and it was not so you could have extra power to run your aftermarket equipment! You must add power if you increase the demand. If you add a 1000 watt amp and a 200 watt 4 channel amplifier and allow 1200 watts to run the car then make sure the Kinetik model numbers add up to 2400. 1200+1000+200=2400. Assuming you are replacing the starting battery with a Kinetik Power Cell, install the size that best fits the space (for example an 1800) and add the rest of the 2400 needed to the rear near the amplifier (a 600). In this car a KHC1800 and a KHC600 add up to 2400 watts total and the car should have plenty of power assuming everything else is working properly."
