  • Big speakers sound quality good at first, poor sound after couple of days use
Worked brilliant for first couple of days now sound quality very poor. Have contacted seller for replacement as it is a very good item hoping I just had a faulty pair

  • Worth every dime.
The media could not be loaded. I have 4 of these for about 4 1/2 years. You can’t beat the sound and toughness of these bad mfs. And I give them absolute hell.

  • Great subs
The media could not be loaded. They sound great in my Honda Civic coupe . I have them hooked up to a 1500 watt sundown amp.

  • Meh
I went from JL W3's to these. Not impressed. The JL's were way overpowered from my amp but did amazing. I figured wiring these down to 2 ohms would make a difference. Nope and they can't handle the power. I've never heard a sub squeak when given it's rated power and I've been into car audio since the early 90's. While they are impressive subs, they can't handle true power. Stick with JL. There's a reason for the price difference. Glad I didn't pay that much for them and lesson learned. ... show more

  • Sound good but let down on them
Sounded amazing when they worked but both coils blew after 6 months of regular use

  • Sundown fan...
Just received two of these bad boys... Not even broke in and these sundowns bang.... Deep clean bass... They get low and punch..... I would recommend these subs for everyday usage.... They will shock you.... 2400 orion cobalt wired down tell these subs nothing... They can take some punishment... Sundown subs are all I'm rocking with moving forward... ... show more
