They make my hair move...sound really great when tuned. And make people angry at will.
Bought 2. Setup in 1Kw 4 ch stereo setup. 2 ch for l&R subs. 2 ch L&R mids highs. For reference music, aka old people moosak. Placed speakers in a dual L&R ported, single passed enclosure. With separate tuned section for mids tweets. The subs ring sweet and mellow on symphonies and bang Space Wizard like a champ. I wanted stereo! love the nice left right hit you get from independent subs! I cant say enough for the Skar value! I know these are value line, not the hiline powerhouse speakers.. But in a ported enclosure. Tuned, crossed and setup. They SHINE! The speakers at 250 watts each are so fricken loud you need earplugs for anymore power. But sound 100% on point NO distortion, butter FAT! Exactly like they should. Yes I can go 500each...why? No one would stay in car with me! They would hit me in anger and leave lolz! Even at half volume i get the are you serious looks . Me- Hey sorry! I may be old, but I too like it loud. He He, think I built it all for you old farts? P.S Observation on humanity! Volume that hurts for one song, a moment later is too low for a favorite song. Derp!

Best 12" sub for the money.
This Skar audio SDR 12-in D4 wired in parallel to 2 ohms and is 600W RMS and I'm only pushing 350 watts into it and it is so loud it hurts my ears being right behind the driver's seat in my Silverado. It was decently priced and even better when they go on sale. I used to have the IX 12-in D4 wired to 2 ohms as well and this speaker blows the other one out of the water with its deep lows and impressive loudness. Definitely worth giving it a try for a budget subwoofer it performs phenomenally. I can only imagine after the break in period. Definitely worth picking one up or two for that matter depending on your setup configuration. One is definitely plenty for me where I have it located. It shipped really quickly as well and I got it on time with my free shipping Amazon prime. Just remember to break it in respectfully. Skar audio recommends a minimum 24-hour break in. At half to low volume and at half too low power just to break them in properly. I only drive about an hour a day so it won't take me close to 24 days to break mine in but once they're broken you can crank up the wattage and the volume and they will sound amazing. I know my IX12 sounded amazing and over 2 years later still performs well. I put the IX12 in my wife's Kia forte and she loves it and it thumps really hard. My point being is if they're properly broke in they will last as any speaker should if properly broke in and properly powered with clean power.

Worth every penny
This is one solid well made woofer. Of course it has to be in right box, but it hits low and hard. I had a bandpass box custom built for my truck and the place installed the woofer in box and wired to the amp. He had a speaker wire for each coil, so to have a 2ohm load he had to put both positive together and both negatives together ( monoblock amp ) well he hooked only one speaker wire to the amp. So only one coil was playing with a 4ohm load so my amp was pushing 300watts instead of 600watts. Unbelievable how this thing was hitting. I would have never known better but I had a wild hair jump up my ass and purchased the Alpine R series 12in. So I only played the scar on one coil for about 4 weeks. Iโm very surprised the coils were not damaged. Iโm sure eventually I would have damaged them but the woofer is still clean and hitting hard. For this price you canโt beat the quality, I think it would be hard to even match power of this woofer.

Sound quality
Most awesome sound!

Sound Great
Well worth the price as it works on lows and intense bass. Ran prior with Skar RP 1200.1l and it blew the subs running at mid capacity. Amazon and Skar Audio took care of me. Now I am pushing four of these with a Hifonics Brutus 3k at a quarter of power and am supremely satisfied. Will purchase for future vehicles.

Highly reccomend
Despite what some people think about skar audio, they are amazing for the price, bump HARD, and have been totally reliable so far. I haven't had any issues with it at all except for it being a little smelly after having it full tilt for a minute (its just because i am severely underpowering it with an 800 watt amp). The sub looks great, and its got some good power to it

Break in! If u don't know go slowly
I broke it in for three days! It was defective! No problem they are made by machine! Replacement! Totally different sound wow! My first one had a wobble sound to it! The Replacement wow ! My chest feels the bass! My amp is 2000 watts. Amp at min putting out 600 watts. This speaker is 600 watts! Breaking in one day! I moved up from a kicker to this NO comparison at all! I waited till I got the Replacement to rate it! It takes everything kind of music and enchanting it. I'm old 70 h o be 71 soon! It makes mx old self think I'm back as a teenager!

Great home subs
Wired up for 8 ohm as a replacement for a 30 year old THX ultra SW-X1 passive subwoofer(120 litre cab) Not quite as smooth on the upper end as the OEM but has great extension and good beefy sound with tons of SPL available running on my Kenwood Basic M2A power amp. (220 RMS both channels driven@8/0.004%,and 526w dynamic power, per channel) Compared A/B with a Soundstage PS12D4 driver from the same price class(and same cabinet/room/amp) it was hands down to the Skar for low end extension. Definitely buying three more for my other cabinets. Both subs ran @80hz LPF.

Best budget sub in my opinion!
Running it is a ported box on a 1200w taramps amp and this sub hit hard! Will be buying another to run 2 12s

It thumps and bumps
Installed this in a very basic 12" ported enclosure, added a 2nd set of terminals to the box to power the two voice coils independently from two sides of a 4 channel bridgeable amp for a combined total of 300 watts RMS, nowhere near maxing out on power (Also still needs to broken at lower volumes) Even at maybe 20% my available power it is quite loud already, I set it up in my basement, powered the automotive amplifier using an old computer power supply and it already shakes the floor above, very impressed by this budget sub. Can't wait to turn the volume up and really see what it is capable of.
