    • 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

    • 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

    • 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

Speaker Size: 10.0 Inches Impedance: 4.0 Ohms
put 4 of these into a 2002 ford ranger extended cab, along with a full interior audio system. the box dimensions i used were 25x25x14”. the box was strapped to the back wall of the truck for seat clearance. powering these subs are 2 Rockville RVA-m3 amplifiers. 2 sets of 2 subs are wired at 1 ohm to two different box wire connectors with all 4 subs firing the same direction. this thing hits HARD and DEEP. it sounds very balanced with a good tune, eq, and low pass settings. i’d 100% recommend these ... show more

    • Good stuff
Speaker Size: 8.0 Inches Impedance: 4.0 Ohms
Compliance curve is sweet. Excursion is good. Fit and finish is excellent. Needs break in. QTS is off. I'm finding a lot of woofers with QTS in the .9 range like this one. Fs is right on. Times have changed and you've just got to tune lower than fs, lose efficiency and roll with it for sq. Or tune high for output. Or go sealed because it's under damped. This is all a byproduct of stronger suspensions in modern subwoofers. This is to protect it from high power and low frequency over excursion. Pretty flexible. Good value. ... show more
