Good size for a Honda civic with 4 door ds18 speakers and 12” subwoofer.
Let customers speak for us
from 3657 reviewsIve got a set of $300 6.5’s in my front doors and decided to put these in my rear doors and wow at how much better these perform and sound.
Will absolutely buy again.

at the beginig I get the 6.5inch but because of the look, design and quality I changed my mind to 8 inch and more quantity. Recomended 100%

Excelente battery

Great quality for the money!

I have many different kinds of speakers trying to find the best ones to fit me and I found them DS18. You cannot go wrong with these. 10 out of 10 recommend these to anyone wanting to upgrade Their sound system!

This amp took the already crazy loud ds18 pros an made them even louder not that they needed a amp but man they sure do get down.

It’s supper Awesome it definitely ups your speakers compared to stock unit it really improves the quality of the sound would definitely recommend this is your sign to get it!

These sound amazing with the 4in towers super loud

This fit perfect and sounds great. =The only problem I have is that is doesnt have a place for tweeters.

Been using for 3 years now. Great amp

I replaced my old and very poorly tweeter from my Markbass P210 Combo with this amazing 1" Neodymium Driver And Horn Kit 160 Watts 1.5" Polyimide 8-Ohm Vc.
I took my time to study whether this project was going to work. In order for this new driver horn to fit my bass cabinet, I had to enlarge the existing hole and when placed, I ultimately ended up using one screw because of the new position of the tweeter horn driver.
Guys, this tweeter Amazing...Highly recommended!!
Perfect sound if you are using a Fender passive J Bass or active... A MUST HAVE!!

Absolute great sound. Huge treble volume from this speaker. Love it

Este amplificador para coches es excelente, produce un Sonido muy nítido muy profesional 100% Feliz

Sounds great price is awesome!

I install these with hertz or precision power 6x9 cut kits in saddlebags. Great power handling, crystal clear sound, amazing volume, awesome tone. I'd put them up against the best from the other big names in motorcycle audio, and they always win!
