What do i need do stop my headlight dimming? Superbank? agm? bigger alternator?

[Wesseat]

My headlights constantly flicker with the bass when I have the volume over three-quarters of the way up. I have and 08 Jeep Wrangler daily driver and a sound quality setup.

My electrical system consist of a JS alternator rated at 300 amps although it only load tests 250, Big 3 kit, and xs power d 3400 agm under the hood. I'm running a kicker class d 1800 watt monoblock at a 1 ohm load and a focal class ab 280 watt 4 channel at a 4 ohm load.



So do you think I should add a superBank or an AGM?


Or maybe even both? I'm getting conflicting answers from everyone.


If the super bank or AGM or both are your recommended solution, how do I wire it and do I need fuses on both?


I have a drawing I will include that shows how I was planning to wire in a super bank. If i need both I will place the AGM right beside the super Bank and run a separate strand of 1/0 to a smd distribution block.

If you have an alt putting out 250 with an XS power battery running 1800 watts and your getting light dim then I think you might have a bigger problem.
I'm running the same wattage with my stock alt(150) and an agm and I don't have any dim.
Does it have halogen lights?

Halogens yes

Here is a video of the dimming

You have all the preventive measures taken care of, so I think your battery may be on it's way out. Not long ago I had the same issue. Shuriken crapped out and on it's way out, it killed the Odyssey starting battery. Now I have 1 conventional battery, and no dimming. I am currently at 2400 watts rms total system power.

The whole system is new.. I did have the battery load tested to make sure and it checked good.

It shiped direct from xs power a couple months ago

Even while revving you have dimming issues. So if all is new, I would definitely re-check the big3. Seems like the grounds are lacking.

I will check those out tonight when i get home and let you know

I know all of them are good except i have not double checked the one from the battery to the frame. We did run an extra cable to the body on the jeep when i was troubleshooting and that didnt improve the dimming.

You need more conductivity between the battery and the amp. If you relocate your current battery next to the amp, I bet it will solve your problem.

@Kickstand what are his bigger problems? That sounds like a vague way to say you don't know what the problem is if your guess doesn't help.

@1aespinoza will probably agree with me after he reads my post as usual.

That isnt really possible without redoing everything. There is only 13 ft of 1/0 premium ofc between the battery and the monoblock and it is pulling 175 amps.. I thought 1/0 was overkill? Actually i thought everything i done was overkill.. Why im so disappointed to be having trouble.

That is weird. I'm running the same amp and no dimming at all. All on factory alt, with agm up front and rear. What model is your kicker amp? The new version that is one ohm stable?

 

[Levelup1]

One more thing, how did you set your gain?
