Have 4 of these on a taramp 8k clamped seeing roughly 1900 a piece, and they take it like a champ. Get stinky at times but still badass subs. Meters a 155.2. Can't beat it for the price.

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.

Heard two of these on a q2200. With the right box and power, you'll be cringing and reaching for the door handle. Stupid loud, especially for the price. When I mean stupid loud, I mean stupid loud, insane. It's one of those wtf moments when you initially hear it. Highly recommend.

I got this sub to replace a Rockford Fosgate 15" P2 and this sub isn't even broken in and it blows the RF out of the water!! Only running about 1100 watts to it and getting tons of window flex with the lows tuned at 36 Hz! Amazing deal for the price and the quality of the product! Definitely satisfied!!

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.

Rating Sound qube return policy sucks!
 
Hi. After being talked into sound qube by a buddy I ordered a hds300 15. Sound real good at first. It 2400 max. I have a brutus 1200 on it only up 15% to break in. I have 2 children and barley play them loud. But yet for some reason the coil came unglued and the come stiffed up. I call the sound qube rep or what ever he is and he was just rude and tells me the warrenty probally won't cover it and to pay 30$ dollars to ship it back and have to pay to have it fixed. Almost as much as a new speaker cost. Anybody else would have just swapped it out. Good thing they only sent one sticker. It would be hard to peel off more than 1. I hope when I get enough money to ship it back they are more of a help than they were on the phone

Rating im impressed every time i get in my truck.
 
I have two of these HDS315 subs in my single cab f150. In a box that is 5.8 cubic feet before displacement, tuned to 33 Hz. I started these subs at around 300 watts each to give them time to break in and even so. These sounded better and louder than my old 15s at full power. Now I just adjusted the gains to get around 900 watts per sub and wow. I never thought I would turn down my bass but these things slam. I set my head unit for bass to -2 and these still turn heads. I cannot believe the performance out of a 170$ sub

My friend pointed me towards soundqubed because i'm a penny pincher kind of guy, but let me tell you, this is no cheap stuff, in a tiny, temporary, 1 cubic foot ported box, this thing flexes my windows with the lows, paired with a q1-1200, you CANT go wrong. This setup slams harder than my friends 2 JL 12s on a JL 1000 watt. I honestly can't say enough about this company, the products are quality, the customer service is on point, and not to mention the prices!! Soundqubed will be getting the rest of my money when it comes to car audio when i upgrade to an HDC3.15 and a 2200. Don't even hesitate buying this or the 12, you won't be dissappointed.
