Hi All, I am planning on building a subwoofer out of the 4 cu ft in the near future. I'm wondering what recommendations people have for the configuration. I have settled on the Stereo Integrity 18" woofer, but what would be the best way to drive it? would the Bash 500W plate amp be a good fit? Does a plate amp even fit on the back of the sub with the way the internal bracing of the box is setup?
