Snoopy what's ya TA login?
I'm b-chi. Been on there oodles. Try not to take offense mate, not in the Ta spirit.
How are people going to learn if people aren't willing to help. It's very difficult to fault find over an internet forum.
Don't mean to offend anyone with this next comment. But there are a lot of people on this forum (and others I'm sure), who aren't into audio as much as say you and I, or don't have masses of experience, or have even been told diff info by a shop/installer so think that's right. Who wants to be proven wrong? Last comments aren't relating to this thread.
On another point. Were you on the M40/A34 junction last weekend LEN. Saw a blue 5 dr with gold rims.
Following on from tobz point. Try a different HU to see if it still happens.
