Hello,I recently hooked up 2 GS Redline 15's and a Lanzar VHC900 Amp.Everything was fine for about two weeks but now I notice whenever I turn on the car(or just the batt.) I get a very annoying high pitch noise from my highs.Now when I am driving, the noise gets louder as I accelerate.It does not even go away when I turn the HU off.Any suggestions?

Also I have noticed when I does this my bass cuts out and is not as loud.

If all was well and then it suddenly started, your amp may have taken a dump. Lanzar is famous for this. Also check ALL the ground connections and make sure nothing has come loose.
