It's a 600 watt sub, so you'll want something that won't over or under power it. The ED NINe.2x amp produces 600w at 4ohms, so if you have a D2 voicecoil configuration, it would be the perfect combo. If you look on ED's website, it's the amp that they recommend using with this sub. I had these two running together...great combo.
Hmmm, and I just happen to have one of these for sale! //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
