14.4vTech

rember one thing, EQ's (little known fact) are only made (its main goal) to cut levels not boost, turning its gain down and not boosting your 400khz and up freqs. will and probaly would have removed most of your noise before doing anything else. one important thing to do most techs in my idustry dont get or understand is case grounding all componets. that means running a wire from case screw of the reciver to case screw of your amps, computers, eq's etc

agreed - grounding is as important as the power input, but people just seem to cheese it a lot.

btw, what industry are you in? only thing that came to mind when i thought of 14.4v was my cordless torque drill...

do you mean grounding all the equipment (eq, amps etc..) together and THEN grounding it to the car? or only grounding the equipment without grounding that to the car?

Oh and your cars system is supposed to charge at 14.4 volts, unseen number for the most



Ground all your componets the way they are supposed to be grounded, then run a wire from the head unit case to the next coments case and from that case to the next it creates more of a stable common ground, all your componets ground to their case.

ground the shields of the rca cables on the back of the radio to the radio.cut a little of the cover off of the left and right channel rca to exspose the shield of left and right channel,take another piece of wire and wrap around both rca grounds and tape up.take other end of the piece of wire u used and put under a cover screw on radio,now it should have no noise.mike
