Summary: This sub is great honestly, very well built, except for the way the positive/negative terminals were. They were just wires instead of being connectors which made it harder for me to install in my sub box as they are short and took more time with stripping and what not.
Summary: I have this single sub wired in parallel in a ported box 1.8cu with a Planet Audio 4000 watt amp. I had to turn the gain almost all the way down to make the bass not overpower. When I push this thing a little bit it flexes my Jeep, the mirrors rattle so hard you can't see.
