Hey all, im tryn to install a leftover woofer i got sittin around into my audio system in my room. im powering the amp with a car battery and then keeping a charger on the battery. im not sure how to get tha amp to turn on though, how do i get a remote wite to the amp? its easy to do in cars, but with no HU i dont really know how. Im runnin the RCAs to the amp from the surrond sound reciever(reciever has a dedicated rca out for subs). Couldnt find the answer when i searched, but im sure its been asked before. Any ideas?
