Dafaseles Posted February 27, 2021 Report Posted February 27, 2021 Do it. Plenty of videos on YouTube to show you how boss. It's good for your system and for your vehicle 2011 Chevy Silverado under construction My build log here. Check it out!
1point21gigawatts Posted February 27, 2021 Report Posted February 27, 2021 Agreed. You need a big 3 on that amount of rms. 1500 rms or more is when a big 3 needs to be done, at least. And at 2000 rms or more is when an extra battery should be added with a big 3. Honestly, 1500 rms an extra battery should be added too. But I’m guessing you are probably using a hifonics amp or something like that, so you just need to do a big 3 upgrade with 1/0 ofc. “How can we help you?” “And don’t forget to tell them that the customer isn’t always right.”

Anthony10111 Posted February 27, 2021 Author Report Posted February 27, 2021 I have voltage drop to 12 instead of 14 when I'm stopped, and my gas gauge is funny, and my lights flicker. But my engine to chassis ground strap is broke .. So we will see the results in a couple weeks..
