Hard hitting subs at a solid price.
Speaker Size: 12.0 Inches Impedance: 4.0 Ohms
Bought a set of these Oct 2023 and they’ve been the most reliable subs I’ve ever owned. Started them out on a CT Sounds CT700.1D amp and moved to the 1000w version. They’ve been through 2 boxes now, the punishment of a dirty work truck, a downward facing box, and hit just as hard as they did the first day they were hooked up. Great subs. Buying one for the wife’s 4Runner soon for these very reasons. ... show more

Great quality!!
Speaker Size: 12.0 Inches Impedance: 4.0 Ohms
This is the best built speaker I have ever purchased. Unfortunately, it did not suit my personal needs since I bought it for home theater before checking the theil and small parameters. An absolute great speaker. This is the best you can buy for the money hands down.

k6 dual 4ohm nice woofer !! loud and deep bass
Speaker Size: 10.0 Inches Impedance: 4.0 Ohms
ok ok so I made the wifes ride my test vehicle I am really happy with this woofer. big woofer with a reasonable depth. nice solid speaker. had to modify the box as the woofer diameter is big and used a spacer to make sure it has room to stay cool but the extra time is worth it. the sound quality is good I crossed it over at 80hz and it will shake everything. I did prep the trunk and doors with sound deadening. bought it to upgrade a kicker comp slim, a nice little speaker (vented) but this is a beast! I was surprised at the sound! I put it in a 0.6 sealed box and on 335 watts rms this is hits very hard! low and deep. part of a 5 channel audio pipe amp class a/b setup in a chevy cruze I ohmed mine out as well and each was 4 dead on and when I wired em up parallel 2ohms even I have 1.2k on 2 10's of a good brand but I going to add 2 of these to my want list they are a bargain ... show more

Very Yes
Speaker Size: 12.0 Inches Impedance: 4.0 Ohms
Current setup is a 1st gen Durango with the rear seats folded down and the middle row removed. I've got a box up against the tailgate/hatch, and i just threw a pair of these in there. Certainly an improvement over the previous units, in pretty much every aspect. Im supplying power to them with a boss audio 1500w monobkock, and im certain that this is a limiting factor currently. Even still, my driving soundtrack tends to become the neighborhood Alarm clock. These speakers make the picture frames on your living room wall buzz and vibrate when im rollin through. Soda in my cup holders go flat in record timing. My mirrors are made absolutely useless when I play something like LTE, XLR, or Glacier Pack... and there's still more to be had once I improve my amp game. Also, they arrived sooner than expected. I did have my worries when only 1 box arrived on my porch - luckily it turned out to be a split shipment and speaker 2 arrived the following day ... show more
