  • Worth every penny
Size: 12" - Dual 4 Ohm
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. I’m very surprised the coils were not damaged. I’m sure eventually I would have damaged them but the woofer is still clean and hitting hard. For this price you can’t beat the quality, I think it would be hard to even match power of this woofer. ... show more

  • Best 12" sub for the money.
Size: 12" - Dual 4 Ohm
The media could not be loaded. 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. ... show more

Size: 12" - Dual 4 Ohm
These speakers are amazing! They are hefty speakers and can really pound. I have two of these hooked up to a Skar 1200W amp, and they are able to shake the mirror off of my corolla! I have been using them consistently over the past two years and haven't had a single issue with them burning out, breaking, tearing, cracking, or anything. I put basic rail covers over them to protect them from other objects and have them tuned so they aren't clipping, if you have any of those happening any damage is 100% on you. These are part of the reason I have tinnitus, but I will never regret it. You won't feel like you are balling on a budget with these! ... show more

  • Perfect! Does EXACTLY as Advertised!
Size: 12" - Dual 4 Ohm
I got a skar amp as well as 2 of these subs, gotta say they sound great and they can take a beating, both sub came FROM SKAR AUDIO through Amazon so expect the best :) they was BRAND NEW right out of the box, I'm only saying this because I've bought "new" subwoofers on Amazon before and they definitely was not new and didn't come from the manufacturer. Hints why I bought these skar subs here from this link. They came with some nice stickers, but I drive around some sketchy places from time to time, (delivery driver) so I didn't put these on my car, the bass from these subs can get low my box is tuned right at 40hz but with these subs they get down in the 30s no problem, I do listen to Hiphop, Rap, Rock, Metal, Dubstep, and they all produce very well and accurate, better than the Pioneer Champion series I used to have. I have these subs on the Skar 800 amp (for now) these subs are fantastic for the price! ... show more

  • Not what I expected.........Much Much more!
Size: 12" - Dual 4 Ohm
I purchased this because I had 2 twelves prior to this on that didn't work out. I just wanted something to replace sound that I was missing. I wasn't expecting what this 12in woofer puts out! Deep, deep bass from a 750-watt amp! I never actually heard of this brand name before, but I'll remember it forever. I probably need to replace the factory speakers because this amp drowns them out unless you're sitting inside the car. I'm totally impressed with this speaker. If I had 2 of them It'll probably be too much (for me). If/when I replace the factory speakers, I'll be looking into this brand, Definitely! ... show more

  • After Three Years of use, subwoofer caught fire this morning.
Size: 12" - Dual 4 Ohm
Worked fine for years. Didn't blow the doors off, but added the low end I needed. Until it caught fire. All settings have been the same all this time, no clipping, clean signal, great wiring and a trusty Alpine 500 watt amplifier that is still working great. This subwoofer catching fire along with speakers sounding muddled and the crossovers being bad out of the box, I don't think I'll ever purchase a Skar Audio product again. ... show more
