  • Awesome speakers!
Size: Dual 12" D4 Loaded Enclosure
Really impressed at the quality and sound of these! They hit pretty hard and can absolutely shake your car. For the price you can't go wrong!! Delivery was on time and no problems at all. Highly recommend these subs. They are hands down the best bang for your buck!!!! UPDATE: After break in running these speakers they kick some serious a$$! I'm really impressed with how hard they hit and quality of them. I highly recommend these!!!! I may end up buying more sets for my other vehicles that's how good they are! Update: going on almost 6 months of use and these things just absolutely pound!!! I'm blown away by how good they are! Hands down these are the best bang for your buck!! I don't recommend many items but these subs, I highly recommend!! I am truly impressed with these subs!! Update: I've been running these now for over a year and these still pound hard! There is no distortion or any issues and are still shaking the crap out of my car! I'm impressed and 100% sold on these! Hands down one of the best sounding speakers I've had in the past 30 years! ... show more

  • Rearview mirror wont work anymore.
Size: Dual 12" D4 Loaded Enclosure
Going into this, i seen alot of negetive reviews online about skar subs. So i was very hesitant. I took a chance on their amps, and ive yet to be let down, so i decided to take a chance on their subs. Its been over a week, and im far from disappointed. They sound good, and they slap harder then will smith at the academy awards ceremony. Definetly get more bang for your buck with this. If your thinking about it, just go for it. ... show more

  • best subs for your money
Size: Dual 12" D4 Loaded Enclosure
very amazing! they fit in my car PERFECTLY! (09 vibe) and they bump hard even while breaking them in still! they dont use up too much power either as i still have yet to get any sort of dimming lights (paired with a skar 1200w amp). these are very possibly the best subs you can get for the value!!

  • Badass speakers
Size: Dual 12" D4 Loaded Enclosure
WoW where do I start these speakers are awesome big bass man. My whole SUV rattles feeling the bass in your chest had them for a couple months and they still hitting hard hooked it up to a 1200 skar amp..

  • So far so good (returning customer)
Size: Dual 12" D4 Loaded Enclosure
This is my second Skar subs and they are nothing but great. I previously bought a SDR 12inch single bundle, which came with the 800w amp and wiring kit. After 6 months, bass becomes an addiction so I spring for a dual 12 system same speakers. I am running it off of the previous 800w amp I have, and plan to upgrade it in the near future. But even the subs being underpowered by 400w the sound is insane compared to just the single alone. Fills the space better, and much better. Remeber 2 week break in period, don’t crank them max 24/7 or they will either smoke/break/tear etc goes for every sub. The car I have it setup in is an Audi TT, with is essentially a smaller Nissan 350z with the hatch back open in the cabin. Absolutely overkill for the car and I love it. ... show more

It's a great buy for the money. I'd say just add a very high quality line pass filter to get the full effect. The ups shipping is the only reason I didn't give it 5 stars

  • Best “bang” for you buck
Size: Dual 12" D4 Loaded Enclosure
The media could not be loaded. Me personally i don’t understand the skar hate, from what I’ve heard from all my skar products it’s pretty solid. As for the sdr2x12 i put them in my 2010 Honda civic running them off an rp1500.1 and they do really good, i recommend putting in a second battery and a big 3 upgrade if you want these and no voltage drop. ... show more
