Going to cause issues even with an extra battery. Not only that a large extra battery isn't going to be much cheaper than an aftermarket alt anyways so it's moot.If I cant mess with the alt for now (pretty damn hard job)would adding one extra battery and maybe a big 3 if I can get it done be good enough to run a taramps smart 3 or would it pull to much from the alt and cause problems. I want to get the smart 3 but I don’t know if my alr can handle it
Most stock alts aren't rated for much higher than what the car needs to run. That's why on alot of cars you'll actually see voltage drop on as little as 700 watts.
The battery acts as a buffer when your pulling more than what your cars alt can create but if you start trying to pull signficantly more power than what it can handle then the battery isn't going to magically make up the difference (your voltage will tank).
Pay someone to install it then. You can't aim at running higher end wattage and then half ass the electricalIf I cant mess with the alt for now (pretty damn hard job)
