Installed a new headunit in a 98 328i with the HK system, but bypassed all of the wiring except the amp remote turn-on and certain speaker wires. Can anyone point out or explain which source would be suitable for powering the HU. The HU is a Clarion ProAudio which does not have a built in amplifier and only has pre-outs. Also, where should I ground the HU near the dash location???
