Awesome Subs!! Poor Box PLEASE READ BEFORE BUYING!!

Subs are amazing, The box isnt good, these speakers have literally ripped this box apart at the seems. I am very impressed with the quality of these subs, they destroy low notes and are breath taking. BUT, recently noticed distortion and could not figure it out. Everything was re-tuned after break in and they sounded great, and all of a sudden it just sounded terrible, so i went to the trunk, only to find the front of the box flapping, Very disappointed in box, the box and subs look great together but the power of these subs just rip it apart... buy subs seperate and build your own box . For the price sonic gave i couldnt pass it up. I would recommend putting additional screws into box before installation if you buy this.

Never a Loose Screw

Easy fix is spray box first with truck bed liner to create strength and let dry or have box reinforced with fiberglass. Never use screws--use something like epoxy glue. Lastly, tune the sub to 30 or below.
