What battery should I get?


Recommended Posts

I’m doing 2 Skar VXF 15’s, 8 Skar fsx65 door speakers, and 4 Skar VX35-ST tweeters. I have a Skar rp4500 and 2 Skar rp150.4ab amps to power everything. At RMS my wattage will be 4800. I have a Mechman 400 amp alt, big 3, stock size battery under the hood, and a xs d3400 for the trunk. So let’s say I’m running 5000 rms just to be safe. Would I be fine if I just got another d3400 or would I need something bigger?

I would say 2 of those d3400's and that 400 amp alt should do you well. If not.... you'd be very, very close. 

Here's a video that can help with choosing electrical upgrades. Granted, it's not the absolute, 100% rule. It's more of a guideline. And it doesn't work when choosing lithium because the discharge and charge rates are so different.
