when my door opens my stereo will stay on but when i close it the stereo goes off.. how do i reverse the trigger? my door trigger stops making ground. so how would i reverse that signal without making another door trigger (actually drilling and making a new trigger itself)?

Use a Relay... Search the12volt.com for relays. Here's a link...

Convert a Negative Output to a Positive Output

If you have a switch or an alarm or keyless entry that has a negative output that you wish to use to switch a device that requires 12V+ such as a horn, dome light, parking lights, head lights, hatch release, etc., wire a relay as shown below to convert the negative output (trigger) to a positive output.

Here's the same configuration showing a negative output from an alarm or remote keyless entry used to activate a trunk release solenoid that requires 12V+ to release the trunk.
