Love it!

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

Wow it crushed my expectation

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

WOW!,,

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!!!

Great sound!!

Sub installed perfectly under passenger seat and has huge sound for a small package!! Love it!!

Finally, plug and play!

The easiest speaker installation you'll find! If you're looking for plug-and-play, these are the ones to get. What an improvement for my Willys! Also, doesn't hurt that their customer service is superb, shipping was fast, and their returns are free!

SELECT 6x9" 3-Way Coaxial Speaker 240 Watts 4-Ohm

Exactly what I was looking for

Was looking for a high excursion woofer with a low tuned box. Type of stuff you have to usually build yourself, but DS18 understood the assignment and with 32mm of XMAX travel in this 29hz box, you’ll get some deep lows without having to push over 1000watts RMS. Similar cone of a JL W series the quality is definitely there. Fits and sounds great in my Tesla Model Y. Box is excellent quality too I love the texture, I put some hook and loop patches on the bottom and it doesn’t slide around at all in the car. Side note I’m using a JP13 to push it and it’s taking that extra power like a champ.
