2011 Mazda 3 S Grand Touring Hatchback 2.5L
So this car was wired for subs prior to me buying it and I’m currently trying to get the battery back to stock
Couple questions about what I have going on here. First, is that fat wire coming from the negative terminal the ground? It looks like it’s just going to the engine bay with some custom mount. Second. What is the taped wire that’s near the fuse box? I vaguely remember the person I bought it from saying that’s the ground but then what’s the fat one? The taped one says kicker on it so it isn’t anything factory
In the trunk, I have two wires, one blue, one black that both look the same gauge. Haven’t followed them so not really sure how to handle them yet but I’m guessing one may be another ground for the amp?Have no clue what the other could be so let me know what you think
I attached a picture of the battery but let me know if you need any additional info
Thanks for the help!!
