  • Sundown FTW again!
This sub is awesome it was in my car for a while , but my amp wasn’t powerful enough so lol , I literally am re doing myself system , second battery and a new 2,000 watt amp just for the U-15 ! You need power to make this sub move , it barely moves on 1486 watts ! Super stiff suspension! Well built and well worth it!! ... show more

  • Amazing build quality, and power handling
This 15 is right at home in a 3.5 tuned to 30hz. Upgraded to this from a rockford t1, and its the best sub ive owned.running on a taraamp 3k ,the sound quality and build is unmatched.

Have it in a 4cu ft box at 29hz in a 96 kenworth semi hits hard and has much better sound quality then expected

  • More power ,more, more
I'm currently running this sub with an X18 V2 D2. It added the punch back that the X doesn't cover. These 2 series compliment each other well. I'm using Hifonics Brutus 3000 watt amps with each sub having its own amp. The coils are wired parallel for 1 ohm . Be careful with these subs as they love more and more power. They can handle much higher than rated rms power with ease without audible distortion. This is good and bad at the same time as you can cook the voice coils without knowing it's at that point . These subs are tough and for the price are worth it all day long. ... show more
