hello
there is probably a simple explanation to this question but i haven't a clue so... when i am driving playing music, it will randomly go quieter for a while then back to what it was and keep repeating that process. is one of my connections bad? it's only just started doing this, has been fine for atleast 5-6 months. if it means, anything it's not a cd, does it on all cds i play and i have a pioneer deh-p7750mp
cheers for any help
