I've owned my Levorg for less than a month and decided something had to be done about the stock speakers cos they were actually painful at moderate volumes on the ear. I upgraded speakers and and also 5 ch amp, installed today. Considering a sub in the near future. Went with Pioneer TS series, more than good enough for me. Stock HU still, not looking to change it. Want to maintain stock.
Only issue is now I have a light electrical hiss at mute or sound turned off (not static). This was not there with the stock setup. I brought this up when I picked up the car, but they said it had to do with the poor electronics of the stock head unit. I'm a little disappointed. It is slightly annoying as anytime you are driving the car without sound there is a slight hiss emanating from the speakers in the background. Not distracting, but not exactly what u want after an upgrade! And this was an experienced car Audio shop who have done the set up very nicely.
Has anyone else who has done speaker and amp upgrades but left the HU as it is experienced the same? Any advise? It's bugging me a little.
