Hi, I have blue 12 volt led tubes on my boat, with just a positive and negative wire, and i want them to pulse to music coming from my radio. I can't find a good way to do this cause i want it a certain way, so if anyone can help me it would be appreciated.

I want to have blue only plusing to music
No mics, i want it to be hard wired like an aux or rca plug
12v

all i can find is rf rgb audio controllers with a aux plug, which i bought, it works but for rgb so it looks stupid trying to power just blue lights

i also have seen this:

but my only question is could that power as many led's as i have and is there a way i can add a sensitivity adjustment to it?

Try connecting the strings across the speakers.

If the output is under 200W (into 1 Ohm), 12V LED strings will be fine.

Isn't that what you want - ie, they pulse to the music?
