Customer Ratings & Reviews

Fit my 2000 Chevy Tahoe!

Battery replaced my dead battery and is being used for my stereo system. Fits my 2000 Chevy Tahoe stock battery mounting plate under my hood, a perfect fit I should say. Easy install. Don't need to charge the battery as it is already rated over 12 volts. Good battery!

great price and specs

The d3400 can be bought for a competitive price bit out performs the competition

It fits perfect in my 02 jeep wrangler. Top of the line product.

I was having winter start-up issues and I have 2,500w system that needed the extra long amps. Chicago -14* mornings are not an issue any more. I have a Tsunami 2 farad capacitor to assist and consistently power my Alpine SWR 12D2 subwoofer. I still have the slightest flicker in my headlights when I'm really pushing the bass but, the sound quality is solid and clear without a stagger. If you are serious about your subwoofer, you will have an XS battery. I replaced a 6 year old Red Top Optima with great results so far. I have to purchase long posts to attack my battery but I don't care. This is a professional product.

Great Products!

Great Products, awesome service/ shipping and deivery turn around. I would recommend these products to any friend.

great value

Awesome battery!!!You cann't go wrong if you bought this battery,That all I've to say guys.

We'll alright

This battery is the shiznit no dimming and can bang with the car off

Great Battey!

This Battery definably a great product for system over 3500 watts amps!! I am using it as a secondary battery to power my NVX XPLD3K and it keep the power flowing smooth and doesn't drop below 12.9V. This battery has a Great Designed case, heavy duty built and delivers the power. What can you say; XS Power!!

Best overall xs power battery

This is my overall best recommended xs power battery for the right price for a highend audio battery to juice up your system. I have 2 in the back of my exployer with d6500 up front on stock alt running 5k system and my voltage never goes under 12.9v

Awesome!

This battery is a huge upgrade over the stinger brand. My subs hit harder, sound cleaner, and I get a higher score on the meter. I will always go with XS Power from now on!

Bang for your buck

Very heavy duty. I have one of these in the back of my navi with a 300 amp alt giving it power. I rest at 14.6 all day and with music doesn't drop below 12.5. XS Power knows what they're doing.

best deal period

Own two. Flawless performance. Great starter battery. Great high end stereo options. BEST brand out there.

Great value

I am using this battery as a secondary in the backseat of my truck and a xs d975 under the hood. They are powering a 2400 watt bass anp and a 250.4 mids amp. Does great my voltage is steady and never goes down when I her on it. And I have a stock alt by the way

The best!!!!

So far, great improvement hope stay like this but look very strong battery and easy to install

solid battery

fits my 2012 impala perfectly. must get something to post though as nothing comes with it

XS is the best!

I trust XS Power for all my car audio needs. Very powerful. Fast shipping as always from Sonic.

Weighs a ton!

Very please with this battery

Very pleased and if you wanted the reserved power you need this battery stacks up with what you need I plan on buying more for my build!

Amazing

Replaced the factory battery in my Impala to help run my 2400 watt amp

Love XS Power products!!

To say I like this battery would be an understatement. I used it as an upgrade battery under the hood of my 2007 Ford F-150 even though its no t the same size as the stock, it still fits well in the same place, I'm using it to power a Rockford Fosgate T-1500bdcp and it does an extremely well job of powering the amp and my truck. Very fast shipping also. I love dealing with Sonic Electronix.

more power

got this few months ago when I ordred it I asked if it came charged he said yes why have I been getting clipping checked battery ohh its reading 11 on meter so make sure its fully charged when you get it cant tell yet how well it works putting in 300 volt alternator this week hopefully this takes care of all my power problems otherwise getting headphones for the car

Awesome Battery Very Durable

100% Beast

Had this battery for a few months to replace my tsunami 10 farad cap and I love this thing. It is strong enough to handle my Hifonics BRZ 2100 and my NVX JAD800.4 with no lights dimming at 75% volume. It is a little on the expensive side but you get what you pay for. If you are looking for a good strong battery, look no further.

good value

I have a 99 Dodge Caravan, I'm running 4 12's (Hifonic Brutus), 1606 Brutus amp, 800 PowerBass amp [highs]. This batter is the only one in the vehicle and the head ligths barely barely deem. This is a good a**battery

XS Power D3400

These batteries are great!! A good step above an optima yellow top if that helps to compare performance

xs power 3400

10 out of 10 that's all I have to say!! Great product

Inaccurate shipping

It was suppose to ship same day and arrive by next day which would have been a Thursday. In fact they didn't process the order till Friday and I didn't receive my package until the following Tuesday. The "buy it before" timer on their site is false advertisement. The product I received was fine but definitely way too late for what it was needed for. I'll never do business with them again. The battery it's self is amazing and well worth the price.

Works Like a Dream

This battery will last and last charge after charge. It just keeps on going. I would recommend it because it is very reliable and can be charged over and over if needed.

its AMAZING

I've had several POS batteries before, and to be honest the price of the D3400 was the selling point. I was prepared for the worst.

THAT was six months ago, and I have been using it daily for lighting in our camper. I have YET to charge it. WHAT A BATTERY!!!!! looking forward to many more trouble free months.

awesome

Got lots of equipment for my son for Christmas, this was one of them. Works great no light dimming.

My D3400

Wanted to test out XS Power so i bought this bad boy as a secondary and it does wonders now that i have my D3100 as a secondary the D3400 will be my primary supply! Great bang for buck!

d3400

Perfect battery for almost any setup up to 3500 to 4k rms sub amplifiers

Plenty of Power...so much I've got XS Power!

I've got this as my starting/system battery and it works wonders. Of course you want to make sure you have a decent alternator. My stock 120 amp alternator and this XS Power 3400 power my car and stereo great. My system is pushing around 2000 watts...at night I can crank the volume, run the A/C, my amplifer fans, and interior lights and i get NO dimming of the headlights. I also did the Big Three Upgrade prior to installing this battery, which is recommended if u really want maximum power. Great product and I highly suggest you get this battery over any other brand. Thanks Sonic Electronix!

Great power

Need I say more than XS POWER. Great battery love the fact that it fit in the space that I needed. 1 of 3 that I have running a Dc Audio 5.0k.

awesome battery

i did alot of research before going with the d3400 and so far i am very happy with my choice just remember to buy battery terminal posts if you need them for your build they are not included.

XS Power D3400

Awesome battery here. A little on the expensive side but worth every penny. Ive had mine for about 6 months as my starting battery and ive had no problems what so ever. Still holds charge like brand new

SOLID BATTERIES

I'd recommend this battery to anyone.
Holds voltage like no other. Have not had to charge it yet (after 1 year of everyday pounding on a stock alt). It holds 12.6 after days of sitting, and I don't let the alt charge it before i park for more than 1 min and I only do that because i don't want to attract attention in my hood, not because the battery needs it!

Do some research on XS power if you still have any doubts and you'll see they have become the #1 choice among car audio fanatics.

Plan to buy another XSbattery or two for my next build!

great battery

This battery went right into my factory location and bolted right in. Performs great. I drive a Saturn LS1.

this battery is da truth

I love dis battery its a beast n best battery I ever had xspower all Da way

xspower d3400 best car battery ever

This is one of the best car batteries that I've ever owned Hands down my lights would go dim all the time before I had this battery you also notice how much your stereo hits so much harder with the XS Power Battery Its a pricey Item but worth it Xspower also has some the best customer service I ever seen I would buy this battery again I guaranteed it

Xs power battery

I had problems with power on my system in my car. I picked up one of these batteries and problem was solved. Definitely worth the money over anything else other than an alternator. Don't waste your money on a bandaid fix with a capacitor. If you want results this is where it's at.

XS FTMFW

I didn't think that a battery would make such a difference in how powerful my system sounds. I have an RE XXX d2 15'' on a 3000.1 amp. my regular acid battery went to junk within the first two weeks of my new sub. Now with this new battery, I also have a small xs battery to help the juice it takes to move the power hungry sub. My voltage is around 15V with the two batteries and drops around to 14 when im around full tilt. Barely dims lights and I am very happy. My roof in my s-10 extended cab flexes on quarter volume, before it needed to be around 70% to start flexing and rattling. I can tell i've got an extra 5 db atlesast just from a battery swap!! It is bigger than a standard battery so be prepared to do some body work. I got lucky and it fit snug. Now i need a high performance alt to take it to the next level for next summer!! XS for life!!

Great Battery!!

Great amount of amps for my system...3k to 1 RMS amp, 2x BL 12's by FI....fits perfect in my battery box....No complaints here!!!

Great battery for the price.

As well customer support from XS is on point. I already recommend XS to any of my friends or strangers who are in the market for an electrical upgrade. Will be purchasing from SE more XS batteries in the near future.

Pretty Good

I Bought this battery back in feburary and i havent had any problems out of it! it use to read 12.8-12.9 volts now it only read 12.5 all the time! but besides that i love it

Voltage problems? Not anymore!!

This battery gave me the juice my amp needs! My amp puts out a little more than 1800 watts rms at 2 ohm.. Before I bought my D3400, my voltage would drop down to the low 12's, but since then it doesn't drop lower then 13.4 on a full charge. If you don't want your pretty new amp you just bought to burn up like a firework then you need this battery. I only gave it a 4 star on "ease of use" because the new battery post's were on the opposite side than my old battery so I have to move around my big three wires.

LOVE IT!!!!!!

I love my XS batteries. Im currently running two of these 3400's in my truck. My sub amp is ran low at .5ohm, so proper electrical is good. Total RMS is around 4200 and voltage is always good. Would definatly recomend this and will continue to run XSpower for a long time.

XS Power FTW

I have one of these under the hood in my S10 and got this one to put in the back to replace the D1200. I know I should have bought the D3100 for the rear but didn't have that much $ at the time. Guess I should have waited and saved up since I still haven't installed it but I'm going to run both the D1200 and D3400 in the rear now. XS batteries are freaking awesome.

xs power the best none better

the best battery ever I have three on two sundown x series 12s sundown 2500 v.2 amp they hit hard sonic & xs power for the win yeaaaah

Awesome

Got this to aide my 2500 watt amp and it does a wonderful job thus far always has the power when you need it. For testing purposes of this battery i was able to run it TWO weeks jamming my system after break in period before it finally lost the power to push them max.. Thats insane. You wont regret putting this monster in your trunk.

top of the line battery

Very strong battery unbelievable power I'm just being honest hands down I'm impressed

Great Product!

I purchased this battery for my 1999 Ford F150 to replace the under the hood battery and I gotta say, it is a great battery. Very worth the price and definitely an upgrade. It starts up faster than ever before and has more than enough power.

Worth every penny

I'm always running my stereo with the truck off for hours and this battery hasn't let me down yet

XS POWER ROCKS!!!!!

SonicElectronix knows quality....Enough said. I ordered the battery for my S-10 as an extra battery for my system. They were the cheapest in product and shipping. The quality of products from Sonic varies. They taylor from beginner to pro, rich to poor and in between. At great prices
I have been a returning customer due to the fact that they always take care of me the customer and to me that matters more than the product I am buying. As far as the battery goes its awesome and has been keeping my amps happy and electrical system steady. I only regret not buying 4 of these instead of one.

Love XS Power.

I bought this for my battery under the hood and I have had no problems with it. Would buy again.

Amazing product from an amazing company

This is a great battery. I replaced my optima red top and have had no problems. Holds a strong voltage and is able to keep up. I just did the big 3 and that made it even more worthwhile. I recommend xs to all my friends and to the serious car audio enthusiasts.

Best Starting Battery For Car Audio

The Xs D3400 is by far the best underhood starting battery in its class (group 34) i ran 1500 rms on just this single battery with close to 0 voltage drop XS is FTW.

POWERHOUSE!!!!!!!!!!!

I purcjased this battery through a different dealer earlier this summer, and i will tell you right now that this battery is AMAZING! Nothing wrong with it at all.... except I'd recommend not swapping batteries at 3AM. :P

great product

I love this product. Only reason for the lower stars is it's a good product just expensive as heck, and it is a lot more powerful than a regular battery but for my system I need just a little bit more. Prolly a bigger alternator. I have the audiopipe apcl-18001d and four kicker cvrs. My truck is louder than it's ever been. Thanks sonic electronix and xs power.

Best Battery Ever!

I Installed this for a soundstream Rubicon 2500.1 and it gave it all the power it needed! I would def suggest it to anyone with a 2000-3000 rms system.
XS Power Forever

Best Value!

Used this as a second battery for my 5000w rms amp, no problems whatsoever. Highly recommended.

xs power d3400

good battery plenty of power

This battery is built like a tank. Has plenty of power. Good price also

Excellent

I have a combined 2000 watt system. Light would dim on heavy bass notes. This did solve the problem. Also did the big 3 at the same time. Shopped around for a cheaper battery but for the specs, this was worth every penny.

Powerful

If Your Serious About Your Power Needs, Then XS Is The Go To Name. Forget The Rest And Buy The Best. XS Power 4-Life! Single D3400 On Stock 160 Alt. 1/0 Wiring And Big 3 No Fuses Running 3200Watts RMS And Rests At 14.4v. Now Most Would Say That This System Is Under Powered. But For The Purpose Of This Review Is To Show You Actually How Much Power Reserve These XS Batteries Contain. Amazing Results And Again Forget The Rest Buy XS!!! Trade Mark That Sh*t Bryson Out

Amazing Battery!

A lot of power never had a problem! Easy install!

By Joe on June 17, 2017 Verified purchase

Absolute tank of a battery

These XS batteries are worth every cent. I used to buy used deepcycles for $150 but never again.

This battery stayed installed in my vehicle for ~6 months through winter while I was out of state. When I came back, it was resting at 10v. I was absolutely certain it was done for.

I put it on a 2A charge for 24 hours. I took it off the charger, let it rest, and measured the voltage: 13.0v. This battery is still good as new. You just don't get that kind of quality from other brands.

Better Dynamics from m y amps

This battery would be great as addition or secondary battery in the system. I have a pretty large truck that pulls a lot of power honestly I could do a little better as a standalone Factory replacement battery. My lights still slightly dim.
This battery is an improvement over the Optima Yellow top I had under the hood before this battery has given me a little better dynamic range and stronger power.

By Brock on February 12, 2017 Verified purchase

Great product

Decided to try xs power and so far am very pleased with my decision..it was priced great and free shipping on a heavy batter..you can't beat that..sonic has been great to work with the staff is always friendly and helpful in my choices..was even honest and talked me out of an item I was thinking about..and actually saved me money

By Crovette on November 27, 2016 Verified purchase

It's got power!!

Bought the D3400 to power my sound system (5000 watts rms total) and it's been great! Replaced my stock battery with it and I've noticed a huge difference one the sounds and I paired it with a high out alternator and it's all the power I need now. Would deffinantly recommend if you need power this battery has power!! The only issue is the terminals that I had to buy aren't the best for connecting their slightly small and will be a little loose if you don't watch it.

Good bang for the buck...

Supplies the power I need in the Bassheadlife,well worth the price. And always a good deal and buying experience with Sonicelectronix.com.

Great value

This is a great item and I will most definitely recommend this website to other

XS power

Direct fit into my s-10 blazer, 1000 cranking amps good reserve power, needs side post adapters for drop in extra 25 bucks but worth it

XS power

Simply the best battery for your after market stereo system or high vehicle application period best price point and longevity

Easy install in my tahoe

This is a great choice at a great value from sonic. The accessories made it a breeze to install in my tahoe and I highly recommend that you invest in them.

D3400 FTW!!!!!!
