I need some ideas as to my rear fill. Im gonna be running them off deck power from my 8445. They need to be 5 1/4's. Not looking for anything fancy. My front stage is gonna be Boston Pro 50's. I would like to keep it under $100. Any ideas? Thanks. Ohh yeah, and there is going to be a Tempest in 3.5cu. ft. tuned to 33hz. If that matters.
