Description

Skar Audio introduces the SDR-3X8D2 triple 8-inch loaded vented subwoofer enclosure for those seeking extreme bass output in their car audio system but who are limited by space in their vehicle. Featuring three of the Skar Audio SDR-8 700 Watt dual 2-ohm subwoofers, this 2, 100 Watt max power loaded enclosure was engineered to get loud and low. Achieve head turning levels of bass output with this loaded enclosure and let size and space limitations be a thing of the past. The three dual 2-ohm subwoofers come pre-loaded and wired up inside of this custom triple 8" ported enclosure with a final impedance load of 1. 33-ohms to a single speaker terminal cup located on the backside of the enclosure. This competition grade ported enclosure was designed for ultra responsive, low end frequency response, with all three drivers utilizing a single large shared chamber that shares two advanced slot ports located on opposites sides of the rear of the enclosure. We engineer our products to not only sound great, but to stand the test of time - which is why we construct this enclosure out of only the finest grade medium density fiberboard (MDF). Furthermore, the craftsmanship and build quality of this enclosure are world class and exemplified top to bottom. One such example of this being a double front baffle for enhanced strength that also doubles as a design enhancement allowing the subwoofers to be mounted with a flush finish. Finally, the loaded enclosure is finished in a premium black carpeting that features the Skar Audio logo centered across the top surface of the box. Peak Power: 2, 100 Watts, RMS Power: 1, 050 Watts.

  • Awesome subs for the price!!!
Size: Triple 8" D2 Loaded Enclosure
I have had a lot of different subs in my life time and these triple 8s are pretty good for the price especially if space is a concern. I'm in korea and i had a super small car something similar to a Chevy Sonic hatch and it fit in the rear with plenty of space to spare. sounded amazing too! Only complaint is that the box is tuned kinda high around 50 htz, and I am use to making my own around 32 htz but who cares it was loud and cheap ... show more

  • Big sound from such small speakers
Size: Triple 8" D2 Loaded Enclosure
Got a little first gen scion xb for a commuter car for work. I like my music. I'm old school.. punch, Kicker, bazooka. I went with these 8s bc I have limited space in the back of that little car. But I have to say, these 8s hit HARD. I didn't expect it. Hits harder than my two cvr 10's in my truck. I never expected this much thump from 8s. Amazed me for sure. Still letting them break in, but even at just half gain, it's almost too much for my old ass. ... show more

  • A lot of bass
Size: Triple 8" D2 Loaded Enclosure
I see quite a few ppl saying these don't handle what they are rated for, these ppl don't know much about car audio it seems. These are rated for 2100 watts MAX/Peak power, they are 1050w RMS. And they handle that just fine. My 900w Kenwood amp powers them easily. They have great sound, and a beautiful look. The bass does drop off a bit after 30hz or so. So anyone looking for serious deep digital/electronic bass will want something else. Also, they claim to be rated at 1.33ohm, but when I checked them right out of the box, they were at 1.6ohm. This matters if your amp is dynamic based on the ohm received. Lower means more power from your amp. But now that they've had their break in period, they might be lower. Last thing. I expected the logo to be cheap paint or a sticker. Nope. It's embroidered on! It's not coming off for anything. Really does look nice.. All-in-all, I recommend these to anyone who listens to Rock, Metal, or Country music. These excel at this. Edit: Replaced my 900w Kenwood as I had to crank the gain all the way up to move these. Replaced it with the Skar SKv2-1500.1D. Gave it a week to settle and break in. The 2 were made for each other. Subs never sounded so good! Keep in mind, these aren't a 1ohm load. So any watts rated for 1ohm on your amp will be less. But still more than a 2ohm load. ... show more

  • Excellent sub box!
Size: Triple 8" D2 Loaded Enclosure
This thing actually improves over time. It is not 15s, but this box hits really good for 3 8s. I am driving it with a lanzaar 1000 watt mono lock and I believe they were made for each other. Some rap and hip hop stuff causes it to drop out at really high volume but can be adjusted with a pre amp. Highly recomnend. Kick with classic rock/metal. You can really feel this box. Excellent!!! UPDATE - This box is now hooked to a five channel soundstream with jvc head unit. Preamp no longer needed. Box still sounds awesome and turns heads. Sound quality is just amazing. ... show more

  • This thing fits in the smallest of cars and hits like a much bigger setup
Size: Triple 8" D2 Loaded Enclosure
I’ve only had one other set of subs when I was 16 they sounded great but I got a truck and well you can’t fit two 15s in a crew cab truck so they were sold I have a small fiesta st now with about the size of a glove box for a trunk and these subs fit so perfectly out the box it’s insane they hit harder than my old setup and if you pair them with a 1000 watt amp it’s too much bass like sound quality is insane I can’t be any happier with this product and I’ll also say the box is all of 100 pounds or that’s what it feels like very heavy,strong product ... show more

  • Quality
Size: Triple 8" D2 Loaded Enclosure
These speakers are for someone who is looking for lots of bass and amazing sound. Note that subs there self are not responsible for sound. You cannot expect for subs to sound good without knowing how to tune your amp. These Triple 8’s are quick to install. And preform good a high power. I personally have had know issues with these around a year of ownership. ... show more
