I have a lanzar vibe286 schannel amplifier, i had it running in bridge mode and it appeared that the speaker wire shorted. As a result one channel works fine while the other makes a continuos thud sound when the RCA jack from the deck is connected to it

Am sorry to say this but you have a bad channel, take the amp to get it fixed since running it like this will burn the other channel,
