Good stuff

We love DS18!!!! Hits hard and is definitely loud

Very clear and loud. These went on a 2021 Tacoma replacing the factory jbl tweeters

Awesome amp , awesome control , looks amazing

Speakers were fine. Sounds great. Shipping with USPS was awful. The package was lost for over a week, and then finally found after I filed a complaint. Don’t guess that DS18 could do anything about that, but it definitely can’t be allowed to become a problem that’s ongoing. Y’all may have to consider alternate ways to ship. Again, very pleased with your product—exactly what my son wanted.

I Have it running to my epicenter from my amp, sounds great!

Comes with everything in picture and very good quality!!

Easy install with the 12in u connect with aftermarket harness adapter. Speakers are clear and very loud. Very happy

Very crispy and clear sound! The tweeters sound great just an over all phenomenal product!

Funciona como quería

Perfect 👌

Puts out amazing power

Bought these to install in my 24 road glide after the update Harley just did they sound amazing but I did need to purchase some spacers so the fits properly I ordered 1/4 spacers for 6.5 inch speakers and the fit in the road glide perfectly the magnet wasn’t hitting the speaker pod after that

Really good power and 0 dimming on lights since installation and the battery itself looks amazing. I like that it can be laid on its side if needed.
