when i turn off my car completely my infinty basslink sub stays on ( its always done this it said it would in the owners manual) but it puts out a huge ass basswave that vibraes the hell out of my car. it only happens when everything is plugge in...when i take away power or ground (obv) it stops and when i take away the lead to the rear speakers signals it turns off. i disconnected and reconnected averything and it stopped, until i closed my trunk then it did it again and stops when i open my trunk. i closed my trunk opened my hood and pulled the fuse for my power wire a and put it back in closed the hood and all was fixed. im not sure what i did to fix this but usually when i tured the accesory on and off it would stop the feedback. anyhelp is apprecitated
