Let customers speak for us
from 3895 reviewsFantastic product. The sound quality just makes trips in the Jeep never long enough... world of difference.

The install was as easy as any modification that I've ever done to my 4runner. The units are well constructed, look good and are a very noticeable improvement over the stock tweeters. Price was very competitive to other brands that required a bit more work to have installed.

Bought this QUALITY CABLE for INSTALLING ALPINE AMP-ONLY Cable U can find with ANGLED RCA - very HAPPY:)

I bought these speakers to fit in the back doors of my 05 Chevrolet crew cab pickup they work great. They Give me more base which paired perfectly with the DS18s and tweets, I have in the front doors just what it needed.
Thanks DS18
I Like it Loud!

NO more then you pay for these they are the perfect upgrade!

Great service and fast wow thank you for packing it up really appreciate the team at the warehouse and sending my shipment with Care. Can’t wait to do the install on my Slingshot. This is gonna sound super loud thank you Team. Really appreciate you guys.

I have been looking for a 2 ohm speaker for my set up foud this one and l love it sounds really good and takes a ton of power

These evl 12s are where it’s at..build the box to specs like it says..hardest hitting subs I’ve bought to date

sound great look good even though you can’t see them in my truck

Fit & finish is very good bought them for my saddle bags on my 2000 road king installed your amp also combined with these speakers Wow very happy with the sound & performance $ well spent if I choose to add any more speakers I will definitely go with Ds18 in the future TY

Alot of sound for something small love it

Best loudspeakers🔥

I previously purchased a JBL rally bar 36 inch and was highly disappointed so I reached out to Anthony at DS 18 directly. He hooked me up with a set of 8 inch tower speakers 500 W he gave me a matching amp that I needed and a head unit, their customer service, especially Anthony walked me through the whole process of tuning my amp And system. It was so loud that we had to un bridge and just hook it up to 2 Channels Way more than I ever expected to get.the JBL rally bar. I couldn’t even hear the music over the motor running in the background very pleased with the product couldn’t be happier
