Feels really solid. Made a night and day difference. Fit great under the seat of my obs.
Wow thing is amazing!! Perfect for my 22 Tacoma extra cab. Surpassed my expectations and some!! I need seat risers to make it fit under seat too much electronics there
Shit thumps for a little thing!! Installed behind my seat in 22 Tacoma xtra cab truck cause it wouldn’t fit under seat. Almost glad because it hits so hard I wouldn’t want it under my seat. Maybee under my chicks seat!! Lol
Very pleasantly surprised!
Purchased on a whim for a JK Wrangler base stereo with an aftermarket head unit. Easy to wire.
Will need to build brackets for under the passenger seat, BUT, so far, this thing is surpassing any expectations I had for such a small, compact unit! It actually shakes the mirrors! More than was expected at this price point for sure!!!
Sub installed perfectly under passenger seat and has huge sound for a small package!! Love it!!
Let customers speak for us
from 3684 reviewsWhat can I say about a fuse holder. It’s mounted don’t worry. In photo it’s not mounted

I put DS18s in one of my jeeps and I love it. I will be upgrading my other two jeeps with the same brand DS18. 10 out of 10 recommend if you’re reading this review get some we like it loud!

With amp i can tell a difference in my 8s . They hit hard with the power that comes out of this amp

These speakers in my opinion out perform higher priced tower speaker from ds18 and other major brands!!!

Love the way it fits, looks and sounds, ds18 products all the way,love the enclosed and padding fender pods, dual 8” on each pod is extremely ideal, because all other products are dual 6.5” only

IXS Shallow-Mount 12" Fiber Glass Subwoofer 800 Watts Rms SVC 4-Ohm

the only issue I had was I couldn't find a radio on (Blue/white stripe) anywhere ut i was able to pick up a Acc/Run on terminal from my relay pack under the hood... and it Rocks !! I used the stock 25W jeep head and NVX dash and roll bar kit and this DS18 SQBASS Underseat Subwoofer im still tweaking the gain/boost/filter for the jeep but its close !!!

Great value sub

This sound bar with the recommended AMP is definitely a big upgrade from factory. It’s super loud. We also had dash speaker/AMP upgrade and mounded the Sub box to the cargo door with 10” Subs/AMP. This sound system is so loud now you have no problem hearing it with the top, windows open, running 80 mph down the road. This was a Mother’s Day gift and my wife loves it.

The power cell solved an ongoing issue I was having. My vehicle has electronic everything. Specifically my power steering, it’s electronic. I would steer and then my radio would cut out. With this power cell installed it hasn’t happened once! My subs sound more powerful than before as well. Over all this was a great upgrade to my ride. Thank you DS18.

I was skeptical ordering these because I thought to myself how much difference a tweeter will produce, so I figured why not. Glad I made this purchase. They are MUCH louder than the factory tweeters, no longer have the volume at 35 to drown out wind noise to hear my music. And they are completely plug and play to the factory harness; these took me no less than 5 minutes to install tops! Huge upgrade at a great price point. Switching all my speakers now to DS18.

These pods fit so nice and look so good. I had dual 6” and I wanted to get dual 8”. I was going to get custom Dual 8” pods but was going to spend three times as much. This was perfect for what I personally wanted with my setup. They fit perfectly into the wheel well without having to modify it. It has a harness that is labeled for easy installation and hardware to bolt the pod down. It uses digital LED lights but I am not using that. This was a surprise and it is a great deal.
