Not sure what happened here.

Today I was hooking up some different speakers in my car to see what they sounded like I hooked them up to my MA Hk398 (in my sig) and they sounded fine.

When we went to put my speaker wire back into the terminals, the car was running and I guess the amp was on, when we plugged the positive terminals back in we heard a very loud pop and heard a loud buzzing sound coming from the speakers.

Now, whenever I play music I can hear the music and the bass (sub is wired to a diff. amp) but there is this obnoxiously loud buzzing noise coming from all 4 speakers (all 4 are wired to the MA)

When we take the rcas out, the buzzing stops, and obviously no music plays. So we think it is either the RCAs or a blown amp. Hopefully nothing is wrong with my HU.

What do you guys think? //content.invisioncic.com/y282845/emoticons/wow.gif.23d729408e9177caa2a0ed6a2ba6588e.gif

I've plugged in a speaker to an amp before while the amp was playing without damaging anything.

you most likely blew the amp. maybe a speaker wire was touching the amp chassis or something like that.

It might be your HU grounding through the RCA I have herd that is a problem for pioneer HUs

TTT I want to see if any one can agree that it is most likely the HU grounding out threw the RCA's.

FIxed. It was the HU grounding.
