    Should I upgrade my battery?

    I've heard yes and I've heard no, probably both from this site. But I was wondering if anyone could run the math on it for me.
    I'm running a carputer off my stock battery and alternator and stock wiring between them as well. I now have an air ride suspension that I want to hook up to the carputer with the Fusion Brain and I'm wondering if the strain of that on the battery/alternator will be too much. I know you need some information from the kit to run the numbers but what information? I can get you whatever you need. I've also got a 120 watt 4 channel speaker amp and a 325 watt bridged subwoofer amp. And as my signature states, a M1-ATX with 4 USB ports used....Wi-Fi receiver, bluetooth wireless keypad, touchscreen and GPS receiver. I'm hoping I haven't left out anything people are going to tell me to search for.

    figure out the total used wattage.., divide by 12 (volts), that will give you the total amperage..

    make sure your alternator can handle the amperage used by ur system (well, make sure that if your system uses say 20 amps, that ur alternator puts out more than that, so that ur battery gets charged) and u should be fine

    Ya the alternator is 70 amps and the compressor for the air ride is 18 amps. I'm getting there.
