major voltage drops

[robertoyoung08 10+ year member]

didnt think a single full range amp of about 200 watts could do this. any help? doing big three this weekend but i shouldnt have to do big three for just a full range, so please help idk why my voltage drops down to 11 with just one amp.

ground on amp?

One of 4 things, most likely #1:

1) poorly grounded amplifier

2) bad battery

3) bad alternator

4) combination of 1-3

battery is brand new. kinetick that i just bought at the end of janurary of this year.

ground. il admit i dont have the best grounds and will redo, but i dont think i ever had the problem this bad until now.

alternator. idk how to find out if its bad? take to autozone or something? but dont u have to pull it out of the for them to check it?
