#1 Skar Audio Single 18″ Loaded SDR – Best 18-Inch Subwoofer for Bass

Skar Audio Single 18" Loaded SDR – Best 18-Inch Subwoofer for BassWe have a WINNER!

Who would’ve thought that a 600 Watt RMS sub could do so much damage?

Brace yourself, this sub is bigger than a regular mini fridge and you will need some help to load it into your vehicle. It’s plug-and-play as it can be. The installation is brain-dead simple you can’t mess it up.

When I first unboxed it I could tell that this was a quality product from the looks and more from the smell of it.

PRO TIP: Load the entire box in the car and only then unbox it. This saves you a lot of time.

The sound quality is excellent and it bumps and vibrates the environment.

This is why this car seat got top of my list:

  • Low Watt Monster: The bass is simply insane that coming out of this woofer, damn and all you need is 600 Watts RMS
  • Plug and Play Beast: You don’t need anything special you just hook up the right wires and you are ready to terrorize some eardrums
  • Head Turner: No matter where you’re going this sub will turn heads because the bass can’t be concealed because it shakes everyone around

A few drawbacks I’ve found:

This is a big and heavy monster; it’s a two people job to get it in the car or you risk injuring yourself and even throwing out your back.

There were a few complaints of sub blowouts and from the looks of it this happens either by powering it with the wrong (cheap amp) or the RMS wattage was wrong.

All in all this 18″ Skar sub does a banging job. Best of all it won’t cost you an arm and a leg. It’s a great banger without the need to upgrade your entire electrical system.

Well the secret is out and the stampede is on its way. If you want to secure your 18″ sub you have to do it right now or risk waiting weeks for the next shipment.

If you want something cheaper, then check out #2 on my list.

  • Produces a lot of bass at low wattage which means no refurbishing the electrical system
  • Attention grabber this is a loud and hard hitting sub so it will turn heads wherever you go
  • Super easy installation it’s as plug & play as it can get
  • This is a heavy sub 2 people are needed to load it in the trunk
  • They can blow if a cheap or wrong amp is used


#2 Skar Audio EVL-18 D2 – Loudest 18-Inch Subwoofer

Skar Audio EVL-18 D2 - Loudest 18-Inch SubwooferHoly smokes what do we have here?

It’s an 18″ sub that’s the loudest I’ve ever heard. Brace yourself it’s rated at 1,250 Watts RMS.

Here’s a Secret: It’s underrated. I’ve managed to successfully hit 1,500 Watts RMS with it and it’s still alive and tearing the universe apart.

Some people say that there’s no break-in period. Listen to me instead. From my experience this sub was getting better and better during this period so ease this monster in.

The bass is loud and hits super hard. Probably it can even crack the pavement and shake the house foundations.

It’s an awesome quality product and it won’t make your pocket bleed either.

This is why it’s a must-buy:

  • It Cracks the Pavement: Oh boy the bass coming out of this sub is out of this world, it’s deep and solid so it will crack something nearby
  • Shakes the Building’s Foundations: Is that an earthquake? Nope it’s just the loudest 18″ sub warming up
  • This Baby is Underrated: Yes they advertise it as 1,250 Watts RMS, but it can do more you can easily go to 1,500 Watts RMS if you need to.

Here are a few drawbacks to consider:

Guys this is not a joke this, don’t try to put this sub alone in the car because you risk throwing out your back or worse.

A few people mentioned that the dusk caps came loose from all that insane bass, well that’s an easy fix to carry out

Skar Audio knows perfectly how to get great performance out of subs without sacrificing a few months’ rent money. I mean there didn’t cut any corners and still have an amazing product at an unbeatable price.

Although it’s a big sub people are on to it. The last time I checked, there were only a few left in stock, and you need to move fast if you want one because you might need a few weeks for the next shipment to arrive.

  • Have you felt a bass so powerful that could crack the pavement? This is what you’re getting
  • It’s underrated at 1,250 Watts RMS it can handle more and it gets even louder
  • I hope your house is insured because it will shake the foundations
  • Potentially you can throw your back out it’s that heavy
  • Way too powerful it can blow the dust caps off


#3 Sundown Audio X-18 v3 D2 Subwoofer – Best Sundown 18-Inch Subwoofer

Sundown Audio X-18 v3 D2 Subwoofer – Best Sundown 18-Inch SubwooferOh please have mercy on my eardrums. This subwoofer made by Sundown Audio is a beast. There’s no better way to describe it.

It’s a hell of an investment and it’s worth it and then some. It’s rated at 2,000 Watts RMS and this is a highly conservative number. The beast can handle more power making it even scarier.

When you get it out of the box it will blow you away and it’s not even moving. The looks are top-notch and very tough.

By far it’s the most reliable and dynamic woofer that I’ve tested.

Plus I did a personal test and see if Kicker or Sundown is the best. I wanted to be a fair fight so I got 4 x 15″ Kicker against this lonely 18″ Sundown sub. It wasn’t even a competition Sundown has blown Kicker away.

This is why it’s a must-buy:

  • It’s Brutal: This sub will shake everything and everybody around you that’s how powerful it is
  • Kicker Killer: This single sub has taken out 4 X 15″ Kickers; it was a shocking result; that’s how good Sundown Audio is
  • Underrated: That 2,000 Watts RMS is quite conservative I’ve pushed it further and this beast was taking it like a champ and wanted evermore

Here are a few drawbacks to consider:

It’s heavy as hell it was pure joy watching 2 delivery guys getting it to my garage and then I had to ask a buddy of mine to help install it in the car because it’s that heavy.

Sundown Audio is known for two things, their high prices and their insane bass so you have to put a serious budget aside if you want to enjoy this sub.

All in all this sub is so worth it. I know it costs a pretty penny but it will run for a very long time, and you will enjoy some head-turning bass no matter where you go.

However, the stocks were running low, so you will have to move fast and buy it, or you will be forced to wait weeks on end for the next shipment.

  • So powerful bass that is shakes everything and everybody around
  • Not even 4 X 15” Kickers could outdo this single Sundown Audio
  • It’s underrated at 2,000 Watts RMS it can handle more and it gets even louder
  • This beast is heavy, it took 2 delivery guys to get it to my porch
  • You need a serious budget because it’s expensive

Btw this is the perfect 18″ sub for DJs because it’s portable and it’s a regular workhorse. A friend of mine who’s a DJ has been banging with this sub for a few years every week for 4-5 days 5 hours each. There weren’t any hiccups or issues.

If you mess a bit with this sub you will be able to shake the house. All I can say is that the price can’t be beaten.

  • Exception from the Rule: You get what you pay for and this is not true; This Rockville is a real gem that delivers big-time without the need of a second mortgage

Here are a few drawbacks to consider:

The packaging could be a lot better than this, if the delivery man has a bad day, then you will be returning it because it can break easily.

There were a few complaints that this sub is blowing in most cases this is user error because a DJ friend of mine is banging all week and almost all night without issues.

OMG it’s a steal of a deal. No wonder people are buying it like no tomorrow. You need to move fast if you want to get one because soon the stock will be empty and the next shipment is weeks from now.

  • The bass is merciless it will massage even your internal organs
  • Bass on a the budget and it reaches the lows perfectly
  • Steal of a deal, you won’t find this type of quality at super low price
