My question is, everytime I turn off the power to the radio, my sub does a one last 'bumb'(the noise kind of sound like a burp, the noise has nothing to do with the song that was just playing, and it is the same noise everytime)... I don't what this could be, I have check my remote wire and everything looks fine, any idea's? Thanks

 

not an expert but i would try swapping out the amp and see if it still happens.

 

my (06 tsx w/ nav) also does this. I am using mercman's cable and alpine pdx amps

 

are you using stock unit? Where is the remote coming from.

 

mercmans cable has a remote lead

 

Yes, I am using my stock Head Unit. I spliced into the stock wiring harness that feed the stock amp.... So I am using the stock remote wire, for the stock amp.
