I am going to take two 10inch sub-woofers, a 400watt amp, and a new car battery and put them into my couch (love seat). I am going to split the RCA cables from my DVD player and run them to my surround sound and amp. Im pretty sure this will work, I just wanted any advise or pointers? How do you think it will sound and should I do anything special to the couch or subs?
