Jessica Posted April 26, 2017 Report Share Posted April 26, 2017 if i have learned anything from car audio its that your current draw vs your expected current demands are not the same. my current draw has always been highest near crossover overlap and then at some point near tuning. im running 2 1500's at .5 each and have a single 1/.0 with a 350a fuse and no issues. take that as you will. results may vary. 160amp alt and 2 g34 batts. drop to mid 11's sometimes, i never back off the volume. Rest in peace, walled 87 accord build log 03' Corolla build with AA Mayhem inside. My super random youtube channel and terrible camera work.

I have a 280a US alt right now, 1 run of pos/neg to back and a single xp3000 currently on a scv4000 and I can easily drop to 10-11v.

Jessica Posted April 26, 2017 Report Share Posted April 26, 2017 im an idiot but ive never lost an amp. i would never encourage someone to run expensive equipment on crap electrical. but music is a weird animal and everyone has a different experience. i will tell you that 99% of people will tell you to plan for the worse and expect the best. i just turn the volume up.
