Car & Bike Need advice on buying a head unit for my car

[xxjayxx]

Got everything done, but I think there is a problem in my amp

What problem you are facing..? Recently i have installed ice in my i10, config is as follows (i am not audiophile neither i know much about ICE, all these stuffs were finalized merely on looks or friends/dealers recommendations) :-

HU = Sony WX-GT77UI
Amplifier = Sony XM-GTX6022 (since it was lil cheaper thn others)
Front speakers = JBL GT5 - S265
Rear speakers = JBL GTO948

Total expense = 21k appx.

The rear channel of my amp is giving a hissing sound. Hardly noticeable but its there. Happened a few days ago.
