Best In The Business

I started using DS18 a couple years ago. Ever since, I’ve stuck with them and recommended them to everyone needing audio. I swear by this company and will continue to do so as every product is beyond my expectations. Whether it’s as small as fuses or wiring or as big as full audio setups, batteries or subs, they’ve always gone above and beyond to help me get where I want to be with sound. Quality is better than most. Many people say “why didn’t you go with JBL, they’ve been around longer.” In return, I’ll tell them they’re overpriced and overrated. DS18 is 100% the way to go for your audio needs!

Hooligan 12 inch subs

Got two of these bad boys in my truck. Ported in from the bed. They sound amazing. Only issue I had were soldering on voice coils broke and it cost my some money on install. But highly recommend these loud *!@ speakers for anyone who wants to annoy the neighbors. Just verify your connections

GEN-X Full-Range Class D 4-Channel Amplifier | 4 x 300W RMS @ 4-Ohm

Speakers sound great in my custom sxs doors but….

Speakers sound great but don’t drop them…. I apparently had slick fingers that day and dropped it. Messed the speaker up unfortunately but still sounds ok lol. Will order another eventually

PRO 6x9" Slim Water-Resistant Mid-Range Loudspeaker | 250W RMS 4-Ohm

Great company

I had an issue with my amp, called customer service and he was able to walk me through the repair/return process. My amp was back to me before I knew it. Very good experience all the way around!!

X 4-Channel Ultra Compact Class D Amplifier 4 x 70 Watts Rms @ 4-ohm

Significantly better than expected

Before putting my system together i watched countless hours of subwoofer reviews and read an obsurd amount of articles. I was on a budget when i went to my local wholesaler who I'd been buying car audio parts from for quite a while. He suggested these zxi12.2d subs. I wasnt sold tho, i went home looked em up and found mixed reviews. The following weekend i went back to store. Dude told me he would give me a deal on 2 of them in a matched ported ported box. I figured I'd give it a try. I hooked these bad boys up to a 2ohm 3k mono amp and was more than pleasantly surprised by how far the lows were hitting, how loud it was for just 2 12"s in a Yukon at that. The power rating seems vastly underrated as others have mentioned, i feel like i put these 2 12s on a 5k or 8k amp to really see them at full potential. Im at 3/4 max power on my amp cant turn it up anymore due to distore from the amp, not clipping on the subs. If anyone has tested these to full clipping and knows the max power they can take constitently in an everyday driver lmk pls. These guys are underrated in the bass head world. Im currently using their zxi 6.5 components on a amp as well for clear and of course loud mids and highs. Thx for the quality products.

ZXI 12" High Excursion Subwoofer Quad Stacked Magnets | 1000W RMS DVC 2-Ohm

Nice clean highs

Easy install. Great sound. Runs with JBL 2"throat and sounds the same. I do remove the phase plug. It is good at distance but not as bright

Great kit.

Kit is perfect. I had way more wire than needed which was great and really aided in being able to tuck everything neatly. Came with everything you’re gonna need to get ur amp goin.
