Yet Another Sound Reactive LED Thread!!!! Answered

First of all caution with the diagrams available on the internet I just fried a perfectly good and expensive car amplifier.

 Can someone please drawn me a sound reactive led strip circuit (as simple as possible) that will work on my car RCA or Speaker Outputs. without frying anything, I can't afford more damage.

What went wrong? What circuit did you use? Pilot error?

It's basicly blew all power supply MOSFETS and the PWM IC of the amplifier.

The circuit was the one on the picture.

You would need to verify the base, emitter and collector connections on the TIP 31. I guess anything shorting or wired incorrectly jolts your system with the full 500-600 cold cranking amps of your car battery.

They are solid connections I solder the connections and used heat shrink tubes to protect them.

I'm willing to buy an off the shelf controller, but I don't want react to background sounds only to the sound signal coming from the headunit or amplifier, and turns on using the remote wire from the headunit.
