Overall Electrical System of my Car

[Savackz]

I have a 1999 4runner. Let me start off that it has an 80a alternator and standard battery right now. XFL1522 powered by a skar sk-1500. B2 Audio es6.1 components and trying to be powered by a mtx rt4240. So, overall, I am guessing around 1700 watts. Now, I need some guidance on what to do for electrical. Some say get an agm, some say alternator, some say both. Now, I don't mind getting an agm but I think my alternator would have a hard time charging both of those at the same time (AGM would be a second battery). If I had to, I could get an AGM (2nd or primary) and sell my XFL and get maybe a SA-15 D4, wire it to 2 ohms, so my amp would power about 950 watts max. I don't mind that at all, but some say I don't have to do that. I already have a box for a 15, so that isn't a problem.

TL;DR - I need guidance on what to do with my electrical. I don't have the money for the new alternator, and I don't really feel like paying for a new battery but if I have to do it, there be it.

I am peaker at 14.4V but my voltage drop goes down to about 13 or sometimes even 12. It'll sometimes stay around 12.8. Then, i turn the gain knob down until the voltmeter go above 14 just for safety.

Thanks in advance! I appreciate all of the input.

If you are dropping to battery voltage a battery will only keep you at that voltage.

To get the most out of stock electrical, upgrade power and ground wires with the big 3 and make sure all connections are made to BARE METAL. I don't know why people are too lazy to sand paint off for good grounds.

80 amps isn't a lot for alternator, but I don't think a HO would be worth it for the power you're running. Connections and wire are most important for you right now.

Maybe you should find another hobby. Either spend the money to do it or get out pretty simple. Not sure why you came on here asking for advice then stating you don't want to spend the money to do what you need to do.

I'll make sure to check my grounds tomorrow. And I am getting a 100AH agm from a buddy and mostly neglo, it's because I'm going to college and need to save for that rather than spending so much on this.

It does get you once you start upgrading. I've spent more than $6k.. haha

Yeah. I realized that now. This is my first system so. I'm learning
