I have an amplifier attached with the sound card of my pc which further has 4 woofers, it was working fine but today some strange problem has occurred. Out of my four woofers only 2 work at a time..... i checked and double checked all connections, changed wires but still its same... When i remove left woofers, those on the right side work and when i remove the right ones those on the left side work... what may be the problem?
Honestly it sounds like you may be overloading the system. You have enough power to power the woofers? What size is that Amp? What size woofers?
