I basically have the same question as the guy above about my gauges dropping when i turn on my stereo. I recently installed a new radio in the car. What would cause this to happen?

Sounds like you spliced into the wrong wire - probably the power wire. When the stereo turns on, it reduces the volts to the gauges.

its hooked up exactly like my last stereo and i had no problems with that one

my suggestion from experience is that the wiring kit on the new stereo could possibly have different or the wrong wiring colors than that of your car or prior sterio... just food for thought though


no yellow is always constant power red is ignition power or memory and black ground then the rest are speakers


besides blue that would be your remote for an amp


im thinkin its a bad gound somewhere but just dont know where to start

You said "red is ignition power or memory" ---- The ignition (switched) power is the yellow wire, not the red. That might be causing the problem.

there is no switched power to my deck it only has a constant power


It has a constant red or orange power to keep radio memory (presets and time) but there is a "remote wire" as Tenspeed said. Its yellow on the radio and it runs off of ignition power and it tells the radio the car is running so it can turn on. If it's always on then the radios power wire is drawing power from the ignition wire and it is staying on all the time because the hot wire is always feeding the remote so it thinks the ignition is on. You got the yellow and red mixed.
