-- [ From: human * EMC.Ver #2.5.02 ] -- >Ah yes , I know we have a galvanized body car, but I don't know that there is (are) a special grounding point(s) in the car, especially in the trunk where the power amp. be grounded. Ben, to minimize noise you should practice what is known as "star grounding. " Every component of your system should be grounded to one common point - and the line level interconnects should be "directional" meaning their sheild conductor must only be connected at one end. Otherwise you get what are known as "ground loops" which can generate noise problems due to the small resistance between different ground points. The cars grounding points are usually recognizable by the fact that several brown wires go to them. They might have o-ring connectors, sometimes there is a nifty multi-male thing screwed down with a bunch of brown wires going to it. BTW anytime you put a screw through the sheet metal you will contact the bare steel. On my coupe I ran everything to the bolts holding the shift lever housing down. Including the power amp grounds - I used some 6 Ga wire, one for each side. I mounted a spare multi-male thing to attach the lower current component grounds to the same bolt. -- "I am a time lord...I walk in eternity" (like lost email) Huw Powell HUMAN Speakers http://www.thebook.com/human-speakers
