Headlights Dimming When Your Bass Hits?? Do This RIGHT NOW! 

Thanks man!

Yo i have the same subs what amp your using ?

@@takeflightleakz8449 Rockford prime R2 500x1 amp for the subs and Rockford prime R2 300x4 for the 4 channel and a sound stream 8x-10.

@@takeflightleakz8449 how about you? What you running?

Thanks man!

Glad it was helpful!

It depends on your existing power supply. If you're in a newer vehicle and running less than 1K watts (especially with a newer, more efficient amplifier like an Alpine, Kicker or JL) then you should be fine.

Big 3 and possible higher amp alternator

As long as you have a high performance battery ... and you've done a Big 3 upgrade, I don't see why not.

Keep in mind the alternator is only throwing out rated output at around 3000ish engine rpm. Not idle rpm which is around 600 to 800 rpm. Its only putting out around a third of its full rated output at idle. Adding an additional battery back by your amps would help to a point but its still more of a band aid type fix. With an alternator that large I would do a big 4 upgrade. Run a 1/0 OFC ground cable directly from the case of the alternator to the negative side of your battery along with your primary engine ground which is usually attached to 1 of the mounting bolts on your starter motor. Also get yourself a wire wheel for a cordless drill and make sure you have nice shiny metal underneath the cable lugs. Any kind of scale etc needs to be removed along with any paint or rust. This is extremely important. Then once you get everything attached tightly take a can of Rust Oleum.spray paint and spray the lugs and panels their to help corrosion out. Also I really hope you didn't use CCA cable copper claded aluminum . You should use OFC Oxygen free copper. OFC is significantly better than CCA. CCA is cheap for a very good reason. Don't use it expeacially on an amp that big. Because you do run the risk of blowing that amp. CCA with get soft with temperature changes causing loose connections down the road it also corrodes insanely fast. You might need to change your battery out with an AGM battery as they can charge and discharge alot faster than a conventional flooded car battery. Also as batteries age the internal resistance inside the battery increases meaning it takes longer for it to absorb current from the alternator. So again it might be time for a new battery. Among other things but thats where I'd start.

Super cap, lithium problem solved

So if i get an amp everything should be fine yes?

I have a 06 hyundai the car has a 130amp alt. Do you think I could run a jp13 amp?

Not stock battery though. You absolutely cannot pull that much without a little bit of reserve power on stock alt.

@@biguzivert to this day I am yet to have issues a bit of light dimming nothing major.

@@riley_400 get a 2nd battery for the subs and you should be fine

@@igamefordays9471 How much agm you got? I get about 1000 watts at 10 volts with no continuous drop. I don’t believe Im getting my full alternator output because by battery is cheapest of the cheap and small with high resistance.

Definitely!

Thanks man! Persian heritage, born and raised in the US of A 💪

So that depends.. What's the year/make/model of your car? What amplifier are you running? Are your headlights dimming, or is your battery dying too? There are a few variables involved when deciding what size alternator to choose. Without getting into the weeds, I'd say a Mechman 250amp alternator will work fine in most cases.

Hey Frank - if we've done a Big 3 upgrade and are still getting lights dimming, we'll try adding a battery. If the problem persists then you're talking about a new alternator.

Getting a Mechman alternator 🔜

Then you've got a parasitic draw somewhere and need to do in-depth testing.

If your lights are dimming then you are losing voltage. Just for a second. That means your batteries can’t discharge fast enough to cover that brief power loss. I would recommend a couple of things. That amp is a class ab? You said 2 channel? If it is swap to a class d. As well change/add batteries to lithium with a high amperage discharge like a headway or a lev60. Then if you still have the issue grab a super capacitor bank. Problem will be gone

@@BassDad my voltage stays between 15.2 (very cold days) and 14.7 (warmer days) it never drops, but I still believe you're correct when you say the battery isn't discharging fast enough. I did buy a 2 farad cap to help, probably won't install until warmer weather. I do hope that'll help, maybe change the 2nd battery (it's agm right now, but underhood battery is a lead acid diehard, Idk if that makes any difference or not) I appreciate your advice sir thank you
