DS18 ZR8.4D 8" Car Subwoofer with 900 Watts 4-Ohm DVC
Let customers speak for us
from 3693 reviewsRecently installed in a 2014 streetglide, power precision ma400 amp pushing 150w each speaker. These speakers easily handle the power, they sound really good and they can get loud.
Minor and I mean a 1mm minor on fitment. They would dang near be flush when installing. But every bike is different.
Good price compared to other top tier speakers.
Shipping was fast, speakers look good and sound excellent.

Back up camera arrived on time and as described. Works just fine. Recommend this seller

Great sound quality doesn’t and super clear purchased 4 now on my way in purchasing 8 more

The speaker covers are great quality and fit perfectly. The price was the best I could find anywhere.

Love these speakers sound amazing compared to my stock speakers

They are amazing just outstanding better then I could imagine i will definitely be installing more

They are very loud and they are clear

What 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 !!!
