i had the sub hooked up via speaker wire to my old htib system. yesterday, i bought a new jvc dvd player with an rca out for the subwoofer. got it home and unhooked the speaker wire and plugged in the rca cable and got no sound. i would turn the sub off then turn it back on and get sound for about 3 seconds. the sub would then click and the power light would stay on, but no sound. i tried hooking it back up to the old system and its doing the same thing. anyone had this problem or know a fix? thanks in advance for any help.
