HELP!! Subs are going "POP"

[smile661]

I just installed a new subwoofer setup. Previously i had 1 MTX TT65 12" and a pioneer GM-5400T amp. I had NO problems with this setup whatsoever. Last night i replaced that with 2 Pioneer TS-SW2501 S4 subs(10" shallow) and a Pioneer GM-D8500M. The subs are rated at 4ohm, i hooked them up parralel to the amp, the amp is rated at 600watts rms at 2ohms and each sub is rated at 300watts rms. My problem is that whenever i change the song, or source or even turn my Head Unit off the subs "pop" and sometimes after they pop they dont work for a couple seconds. I checked my amp ground wire and it is good. I then grounded my HU, then grounded the RCA shields on the HU and that didnt seem to have any effect. I need some advice, i am absolutely clueless rightnow to what may be causing this.

I have checked my connections and they are good, like there isnt a speaker wire touching ground or anything.

you tried grounding your rca cables to the hu case? or a ground loop isolator that will atleast tell you if its a loop or not.

I grounded them to my HU case, and my HU case is grounded. I checked the continuity of it to ensure that it was grounded. I only did this because i had seen it somewhere and it was supposed to fix the problem, which it didnt.
