Question thump when switching source or tracks?

I have an Alpine CDA-7897 2 PPI amps and an IDMAX. The grounds are good & I believe teh RCA's are too. But when I have the stereo on lowish volume & I switch the source from FM to CD or when I switch tracks on a cd, the sub makes a small "thump".... how can I get rid of this? What is causing it?

I have heard of turn on/off thump but this is while switching tracks or the source..
