Let customers speak for us
from 3479 reviewsSpeakers 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!

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.

DS18 BB5.6UF/100V-10PK 5.6uF 100V Non-Polarized Bass Blocking Capacitor

I needed to upgrade one of my amps to have more rms to the new set of door speakers I am running. There powering ds18 neo series. And the way I needed it mounted under the seat there was no way a normal amp would fit. For a small foot print pumping out over 200 rms in a reasonable price this met the needs. Haven't had to worry about clipping with this amp like the other one from another vendor.

I love the Infinite INFINITE 35 AH battery installed it on my 2013 Can Am Maverick 1000r and it has enough cracking power to start it every time see how it does when i add accessories

I love how there loud and everything but I had one go out on me
