So i have two 12 inch dual subs with these slick blue lights attached. Now what i have dreampt of for so long is some way or device to syncronize it to the beat of any given song. So it dims and brightens to the beat. Does anyone have any idea how i could go about doing this?
They have a sensitivity knob. They can be set to be anywhere from so insensitive that they would just barely respond to a 500 watt stereo, to so sensitive a whisper will set them off. I do have to warn you, every third LED blinks on and off steadily when it's not receiving any sound. It's not very annoying, but that's just me.

You need the appropriate resistor. Just hook the positive side of the LED to the positive side of the speaker output and negative to negative. I need to know the maximum voltage of the amplifier speaker output in order to recommend a resistor. Do you have a multimeter? Or at least a voltmeter? If you do, crank the musice up to the maximum level just before distortion and with the speakers disconnected, use the voltmeter to measure the voltage. You'll need an AC voltmeter because the output to the speaker is AC.
ok i will do that, but can you know what you need to if i give you two links that give you the info on my amp, http://www.amazon.com/dp/B000AY63ES/ref=asc_df_B000AY63ES840370?smid=ATVPDKIKX0DER&tag=dealt15900-20&linkCode=asn
The page doesn't mention the voltage on the speaker output. A decent multimeter isn't very expensive. Here's a decent one:

It's very helpful. And well worth the money.
EDIT: I'll also need to know how many LEDs you're using.
Oh, and I'll need a link to the site where you bought you're LEDs. I need the voltage and amperage for them.
when i tried it, it was continiously changing, should i choose a songs with a lot of base and just give you the highest number without i record with the subs connected?
it says rigth on the back of my subs that the LEDs require a 12V power supply, as for the amperage, what exactly is that mesured in because this is quite the hunt for info due to the fact that they are an older model
The voltage is constantly changing. Did you make sure to use an AC voltmeter? If so, try playing a continuous tone of a specific frequency, probably somewhere between 20 Hz and 50 Hz. You should get a constant voltage using an AC voltmeter, but I'm not sure. If you don't have a test tune, just put in a song with a lot of bass and give me the highest recorded number.
The LEDs current is rated in milliAmperes (mA).
I'll try a different voltometer, but i almost sure i took it right. I ran into a problem while reseraching. I read that with my specific built in LED's that it is meant for a 12V DC power source, and in face it advises specifically against hooking it up to the audio.
If it advises against hooking them to the audio, you could always build your own lights.
Or if you prefer, you could buy these:

I have one myself and they work great. They have a microphone and are very sound responsive. They don't hook directly to the audio and require a seperate power source, but they have several other patterns besides sound responsive.
ya, well thanks for your help all the same, so these interior lights... is it super sound responsive, or not a huge difference. Because really if i bought it it would be for that above all else. so from someoone who has is what do you think?
well i purchased the 7 color version of what you recomended, it was only 2 bucks more i figured it couldn't hurt. So in a round about sort of way problem solved ha ha, I will have lights that pulse to the beat of my music! I learned a lot and am extremely appreciative of what you did to help!
I purchased the blue because that's the only color I need. Blue is really the only color that matches my new custom interior (two-tone black and grey).
If you do get some, you won't be disappointed. Just make sure they're legal where you live. They're not in my area, so I have a triple redundant hidden switch system that makes it nearly impossible to accidental turn on.
