I need some input on what subs I need to get for the box I recently purchased. I bought the dual 10" Zenclosure box with the amp rack, and I need some help picking a sub for this box. I am really looking for a LOUD setup. Sound quality is important, but not so much as SPL. Also, maybe some suggestions on a matching amp to go along with the subs. My budget for the subs and amp is from $400 to $500. Thanks in advance.
