I installed a Kenwood DMX7706S Media receiver with 4 6x8 JBL GX speakers and a Kicker CX 360 watt 4 channel amp. Installer put in a special little kit so I can still use the door subs without the thump. Been VERY happy. I am into my music weather at home or on the road. BTW I also installed a backup camera hooked to the Kenwood. Love it!
