Does exactly wht it claims, same exact thing as a DD, which is a very good and expensive brand but this one is less than half their price. It sounds very deep, amazing, cery loud with the right amp, cheap ones will make its limit alot less than it could be. If you have never owned a sub or a very loud one i would recommend just getting one of these and do it all right or take it somewhere it will be done right and your ears will ring. Makes my windows flew( not at full power) break it in right and upgrade and door speakers that are not atleast 50 watt rms, or add tweeters. Looks a hell of alot sexier in person, huge as hell. If you are looking for subs to break windows this is not it thoue, it will moke them for sure but not break them, 2 would, ir the hdc levels probably. Box built 4.5 cubic ft, tuned 33-35 herts. You will not find another sub this amazing for the price, as loud if not louder than any memphis mojo or crossfire ive heard. Subs this loud and good are priced atleast $1000 so take this deal guys, everyones been impressed with my single 15' and im sure your neighbors will know who you are after jamming this one around, turns heads, and dynomat is a good idea unless you want your trunk to rattle like a snake. BUY THESE SUBS GUYS, dont go anywhere else or believe anyone saying to do otherwise. These are awesome. Thanks!(:

Rating Awesome sub!!
 
I've owned a lot of subs in my 22 years of driving, everything from old school Soundstream SPL, Kicker, PPI, JL Audio, Diamond Audio TDX,Rockford Fosgate, Sundown... You name it I've banged it. These are THE BEST I've owned!!! I have 2 of these in a 5 cubic ft box tuned to 30hz running off a RE Audio 5000.1 in a four door f150 with the back seats removed to fit my box, amps and extra battery and they have my truck flexing like crazy. You can hear me coming a few blocks away and they're not even broke in yet. They hit low and clear. I can't believe these subs are under 200$ and are easy to rebuild if you damage them. Now I have to decide if I want to wall off the back seat area and add 2 more of these monsters. Sure I may go deaf but it'll be fun doing it. LoL. I'd recommend these subs to anyone that wants major bass without breaking the bank.

I just recently got this 15, and I am very impressed by it. This thing is very very efficient! I have this in a custom box at 4 cubes tuned to 34hz and it sounds great. The most supposing thing is that I am only putting 500 watts to it right now till I get a q1200. I can't wait till I can hear it at full power. Get this thing and you will not be disappointed, it's well worth the cheap $170 they are asking.

Rating I love it.
 
This is probably one of the most amazing subs I've ever had. It isn't the highest model or the most competitive sub on the market but this thing sure packs a mean punch. I use to have a complete Rockford fosgate system and anyone who knows anything about car audio knows they have good products. Well this hds315 blows my p3 out the water. The dms rating on this one was the peak on the other. I paid a little over 200 for the rf 15 and got half the power of this monster. I love this sub. The only down side is that it needs so much air space. I have a custom built 2.65cu box and it's way too small for this monstrosity of a sub. But when your an all out basshead box size don't matter. I'd recommend this sub and have recommended it to many people so far. I'm pretty known in my town for my system and this sub just blew me over the top. I'll probably be adding a few more of these to my system. Don't even think twice about buying this. Just get it.

First off im 17 and went from having 2 dual 12"s "the Walmart special" to having this beast of a sub. Im running a Pioneer Gm Digital series 2400 watt amp wired to 4 ohms so about 500 rms to break in, in a 5 cubic ft ported box. This sub bangs! Shakes my bones and makes my ears itch and tingle. I plan on running it at 1200watts rms at 1 ohm i know it will be amazing. Highly recommended you will be impressed.

I have a single HDS315 running off a Sundown SAZ1500 at 1ohm. Now I opted for one of the Soundqubed Atrend enclosures to hold me over until I can get a custom built. Not too bad. I think in a custom enclosure I can pull more out of this sub. But for right now I gave it 4 stars.

Rating Very Impressed! ..With only one!
 
First off, I'm 17 and this is my second build and I must say I am very glad I chose Sound Qubed. I just got this massive sub hooked up and installed last night and I am already very impressed. It's in a 2.75 cu. ft. box (net) that's tuned to 32 Hz. This thing pounds out all the low notes! I'm running it off of a HiFonics 1100 watt amp at 1 Ohm. That amp is only temporary until I break it in, then I plan to upgrade it to the 1500 watt version;) I haven't even turned it up past half way on the bass knob and it already starts to thump. I am very pleased and will deff be buying from these guys again!

As a long time customer of Audioque, Ive owned the entire line of HDC3's so I figured Id save some money, and try something else out. The HDS3 is a very good subwoofer for the price. I might just trust SQ with my business, as quality is still the same, and I was able to save some money lol.

Rating From Kicker to SoundQubed!!!!
 
I went from 15" cvr kickers and got these HDS3's 15" model of course, and the side by side comparison is just funny. I literally have DOUBLE EVERYTHING that the CVR's had. I'm talking excursion room, tightness, not the weight so much (not a bad thing) but the spider wires were double in the SQ sub, and tone... just taping the cone of the subs with them in the box and its clear, that the SQ'd sub is deeper just in the thud it makes. The surround is so much beefier, and the sound qubed sub just looks.... legit. It literally makes these kickers look like a joke. What was I think buying kicker in the first place.

Ordered the hds to replace my hdc3 after the motor shifted, kinda just wanted to experiment since I only had a Q1200d on my hdc3 so I knew I was under powering the hdc3, installed the hds300 today and on my Q1200d (on low volume for break in) already sounds better, deeper, and louder on 1200rms than my hdc3,the price and being half the size of my hdc3 made me skeptical but boy was I wrong, dnt hesitate to buy it, 1200rms and down go hds300 wouldve given 5 stars but ive only had it a few hours

LOVED these subs till one came apart. Not sure how or why. This is the second soundqubed item I have had go bad. They did stand behind the 1st one, but being from Canada shipping killed me. I just cant justify sending this sub back for warranty. I had 2 12's on a fosgate t1500bdcp, worked fine for the first few weeks. Then the rattle started. I have given up and went back to my sundown.
