Running an AVIC x930-BT through a Shelby kicker 4.1 amp in my Mustang. The problem I'm experiencing is with fade. While my front speakers are beautifully amplified, I can hardly hear my rears at all.. (need a fade setting of 6-8/15 for any sound) and even faded they don't have the amplification that the fronts do. The instillation was all plug and play (this system has 2 door woofers and a trunk self-amplified woofer as well).
Anyone else having amplified or non discrepencies between front and rear with their HU output? Thanks to all that reply, enjoying the unit otherwise!
