does anyone know how id go about syncing my leds to flash to the beat of the music?

I believe the proper way would be to get a sound module, they usually can be gotten fairly inexpensively for a cathode kit, I'm sure they have led kits as well. I've also seen people hook lights up inline with speaker wires coming off of an amp and having mixed results.

Whatever the results, sooner or latter a blown audio output is certain. You can't possibly match the ohm impedance to do this safely. There are alot of LED controllers out there like this one @ http://www.oznium.com/cathode-music



Just google LED Controllers if you want more.

What if i have multicolored leds??

They would all blink at the same time and rate. If you already have a "Kit" that comes with a Controller that doesn't have music beat mode, your not going to be able to add it. What you have is what you have. There'* no "magical interface" to accommodate a prewired, preprogrammed kit.

they also go for like 5 bucks on ebay including neon tubes
i had them back in my "rice" days lol

Well girls like them, therefore i like them. Theyre happy, they like to make me happy, so idc if its ricey haha. Ya idk ill just go buy new LEDs lol
