Thanks for providing this math! Actually my amp is a Power Akoustic 2500W, which was like 90$, I'm assuming it creates 1/5 of the wattage, like you said, (not making any promises). But yes you are spot on with your assessment! Now my goal is to ultimately end up with a battery-less circuit system where the lights to can light by using a converter (possible adjustable for more wattage and voltage).500W into 2 ohms= 32V RMS or 45V peak. Of course the 12V string of LEDs burn out.
Maybe your amplifier produces 500 Whats which might be only 100 Watts. Then the peak voltage in to 2 ohms= 20V that will also burn out the LEDs.
I think his idea is actually pretty sufficient. I'm looking to narrow down my options but still test what available options I have, you know? I want to veer more in the path of battery-less circuitry for this setup, if I can't, I'll be more than happy to work with the microphone aspect.Don't drive the LEDs from the subwoofer.
What you need is a separate 12V supply to power the LEDs.
I like the idea @Yaakov provided of using a microphone to detect the sound wave from the speaker. You will need a microphone preamp and signal conditioning circuit to filter the desired frequency and modulate the LED brightness.
In this case, I would need a 12v mic preamp? or something smaller?Don't drive the LEDs from the subwoofer.

You can buy me a pint of beer if ever you are this side at the Atlantic.Do you mind emailing me? It's my username @gmail.com. I'd like to give you $10 for helping! Also, what circuit website that makes these would be able to create this for me? Also how many 12v DC Amps does can this circuit handle?
I don't plan on piecing everything together, which means there is no complete circuit build. He think he asked more for specifications regarding if I was to set up the circuit like I have. Think of a regular subwoofer setup with an amp. I would connect the LEDs to the subwoofer input from the amplifier to then light up the LEDs. No series resistor, no crossover. I'm trying to light 2x LED Halo Rings that require 12v, .21 amps each. Which I'm assuming total requires 12v and .42 amps for the entire LED setup.Perhaps the TS could provide (as has already been asked) a CIRCUIT diagram of how the LEDs are connected now. Do they (as has also been asked) have a series resistor? Is there a crossover? How many LEDs are you trying to light with each output? A small amount of power could be drawn from the amp output (some basic circuitry required), and the TS could decide whether it affects the sound quality.
You need 12VDC to power the LEDs. Is that correct?In this case, I would need a 12v mic preamp? or something smaller?
EDIT: From what I'm seeing product wise, am I able to get the circuits for under $50? I'm really not trying to spend anything over. If so, would you be able to point out the specific products? Again, not to keen to the circuitry aspect of electronics lol.
You don't have to for free, exactly why I'm offering money. LolParaphrasing Rear Admiral Joshua Painter,
"Engineers don't take a dump, son, without a schematic."

I could just add spot in the subwoofer box to plug in a 12v Duracell rechargeable battery.You need 12VDC to power the LEDs. Is that correct?
Don't worry about what mic and preamp voltage you need. That will take care of itself, so to speak.
A couple of transistors in a properly designed circuit will take care of it.
All you need to decide is how you are going to get 12VDC, from a battery or a wall-wart?
You missed the point, again.You don't have to for free, exactly why I'm offering money. Lol
Sometimes you need to say the same thing multiple times before the member gets the message.
OkYou missed the point, again.
Basically, you want to do something different from what you have now. Nothing - n.o.t.h.i.n.g - will give us a better starting point than clear and unambiguous information about what you have now. In electronic circuit discussions, almost nothing is less clear than text or more clear than a drawing.

Thanks for specifying this. I guess I should have mentioned the fact that its a car amplifier powering a subwooferThe amplifier mentioned is for a car that usually has a 12V battery.
Mr. Green can view the LEDs when powered from 12V in a car that has its motor running (charging the battery) to see if they are bright enough and if they survive being turned on for a while.
Then a simple circuit can sense the subwoofer output and drive the LEDs with brightness related to loudness.
If it is a car amplifier powered with 12VDC then you already have a 12VDC power source. No need for another set of batteries.Thanks for specifying this. I guess I should have mentioned the fact that its a car amplifier powering a subwoofer
