  • I love these subwoofers. There are better subs out there but these have great sound.

  • This sub is exceptional for delivering strong mid to low frequency bass. It hits hard and is perfect for me when I listen to Rap, Hip Hop, Dub Step etc.
  • When the sub is playing quietly, you get very strong distortion at low frequencies.

Kicker L7R (45L7R152) 15-Inch (38cm) Subwoofer, Dual Voice Coil, 2-Ohm
  • The UniPlate™ pole piece and backplate were designed to manage heat. They wick it away from the internal components of the subwoofer and dissipate it into the surrounding atmosphere.
  • I installed this speaker with my 750 watt kicker amp and wow this speakers bang the crap out of my car it's soooooo freaking loud!
  • This subs is the best of the best I really recommend this subs to everyone you are not gonna be disappointed of this subs.
  • The construction does not look sturdy, which is alarming. Constantly something falls out of him.
  • After a while, it started to get hot, so you have to turn it off after a while and blow it to cool.

Kicker L7R (45L7R152) 15-Inch (38cm) Subwoofer, Dual Voice Coil, 2-Ohm
  • I love these speakers! Just hooked my system up and it pounds! Shakes my whole vehicle.
  • Connected to an 1800w Kenwood amp pushing 4 Ohms and it jiggles the cartilage in my nose.
  • Just make sure you got it hooked up to a good quality amp, and fuse everything and it will show a real sound. Connects to all Kicker amplifiers.
  • Only other suggestion I would have for Kicker would have been to use screw down terminals instead of the spring loaded terminals.
  • The connectors for connection the inconveniently located, cables are constantly confused and you need to pull one through the entire subwoofer.
