HEAD UNIT TROUBLE AGAIN!!!!!!

[littleC18]

when i turn my music up about past volume 30 it starts making this wierd crackling noise from all the speakers that are connected to the head unit. at first i though it was just the tweeters but its not, its on every speaker.

So i turned it up futher and the crackling eventually goes up beyond the music volume and there becomes no music playing at all.

Its a Pioneer DEH-7000ub
I wish i had never bought it now. it just keeps going wrong. £200 down the drain.

I've checked all connections. everything seems fine. i even put one of my brand new speakers in and it was doing it. I started right after i just tried a new JL audio sub that i got. I dont recall it crackling before and it deffinatly wasnt doing it this morning.

Anyone got any ideas?
Anyone want to trade headunits?
Anyone want to fix mine for me?

sorted it. had two bare bits of speakerwire in my back doors cuz im fitting some speakers and they were touching each other, i just seperated and wrapped some tape around them and it sorted it!
