XS Power batteries may seem a bit pricey, but they are worth every penny.I have this battery paired with a high output alternator to run a ~6kW rms sound system in my 2017 Jetta. I’ve had absolutely no issues with dimming headlights or anything relating to excessive power draw.

Second XS D3400 in four years. Vehicle has HO alt and overly built electrical, with multiple runs of 1/0. Only supporting one RF T1500 and one RF T600. Every winter the battery struggles, even with an AGM trickle charger connected. Both batteries stopped holding charge and stopped cranking on startup. Very weak compared to other brands. There is only a 3yr warranty and XS only will cover it, if you purchase from an authorized dealer (Amazon is not one). The line for customer service is always busy and they never call you back if you leave a message. I won't be purchasing any future products from XS Power.

Provide all the power I need.

I got tired of replacing my tiny factory battery and opted to upgrade it I order to accommodate my new audio system. It was a pain to find terminals that would fit but anfter many trips to anuto stores I eventually managed to get it to work. It ran like a dream for 4 years. Purchased 5/2020 and it died 6/2024. The only problem is the delivery time needed when the battery dies. You’ll either be left without a car for a week or have to buy another type of battery from the local store.Fortunately for me, I have a battery tender/charger and it manages to pump just enough charge for me to get a single startup. Tedious but worth the wait.

Using a smart bass 3 and two AB xfl 12s. I read so much about how anything over 2k needed alternator upgrade, etc. But I gotta tell you.. I turn the volume up to clip, which on these subs is dang loud. And my voltage stays at 14.7. I thought my volt meter was broken. Then finally it began to dip super hard. To 14.4 lol. So I'm like wow, I think I can run all 4k of my power on stock electrical with just this one battery. Maybe if you run your system nonstop while driving, you will eventually run out of juice. But for me, I only play the music loud maybe a half hour at a time and the rest is probably pulling maybe 500w tops. Just at everyday listening volume. So for me, it's been awesome. It gives me the power when i feel the need for it, voltage stays strong and no dimming unless I really go crazy and even then it is only the trunk lights and dome lights, the headlights aren't really noticeable. This is on stock electrical so I'm even surprised that it does this well. Before this battery, no chance I was doing more. I was on 1200w and it was dimming like crazy. So not only am I on triple that power now, but the dimming is barely there. And the voltage appears to be extremely strong. This battery is really powerful. To hear the power from this setup and know most of it is coming directly from this battery is extremely impressive.
