I went out for an enormous meal with people from work today. I think it's affected my sleep pattern, so I keep popping around and managed to end up surfing through really old articles.
This thread is a PERFECT example of how NOT to install car audio. Right from the first couple of messages Chris was pointed to the problems (some of them) but didn't do the rest of the required leg work to fix it/them.
He's got power and ground issues to both his amplifier and empeg. Grounds are not made to struts or other vertical spot-welded or bolted parts of the car. Grounds are not made through screws or bolts. You ground direct to bare metal on the pan (that's the bottom) of the car. The bolt only serves to hold the ground connection.
Never use a ground wire that is thinner than your power wire. Always use power wire that is of sufficient gauge for the current being drawn. Do keep the ground wire short from the amp (wherever the amp is mounted). If possible, ground all head units (including the empeg) to a good ground spot near the mounting location and not the lead on the factory radio harness (most factory grounds are crap).
DO *always* go through the basics of car audio: http://www.eatel.net/~amptech/elecdisc/caraudio.htm
And if installing something like the empeg, always DO try it at home with the included AC adapter before starting to freak out about the sky falling with your car installation.
Anyone ever hear from this guy Chris after his last post calling it quits?
