LEDs with subs.

I did this in my 5th ave. I made a quick circuit using a bridge rectifier, Zener diode, a few resistors, and LED's. Worked perfect for years. I had the port facing into my interior and wanted a glow to match custom LED lighting. Voltage from the amp output is what drove the circuit wired in parallel with the subs but the input impedance was high enough to not affect the amp.

About $10 in parts. I can find the schematic if someone is interested. Just quote this post.

Yes please!!

I put two led's in the port. they strobe with the music, since they get their voltage from the amp. I used a Zener diode in parallel with a led and a 120 ohm .5W resistor. finally, another 120 ohm .5W resistor is in series with this combination so the current is controlled when the Zener opens and the sub still gets almost all of the power.*I can draw this up later. The voltage rating for the Zener diode and the LED resistor determines the drive current for the LED. You first choose the LED you want to use, then the voltage drop and drive current rating determine the Zener diode rating and the resistor size.

Nifty! Thanks! I think I am going to use the, Music Interface » Buy Now at StreetGlow, seems simpler. Going to get my 12v LEDs through that site too, seems a bit more then most sites but nothing but great reviews so I don't mind the extra dinero.
