Hypothetically speaking, the strip of LED's inside my subwoofer enclosure...say it were to be wired differently then it is now.(to a seperate battery switch operated) If I bridge the connection ontop of my subs' connection on the amplifier, find some kind of in-line resistor to GREATLY reduce power, since power is sent to the subs on the beat of the music, theoretically, would my lights flash in this fassion with the music?

AMP is a Rockford Fosgate 2 Channel PUNCH (p200-2)

LED lights are currently run to a 9volt switch, but dont run that bright.

If this could work, someone please help me do this!?

no you need more components than that.

just by a sound unit, there are many available. you can rewire them as needed it isn't too hard to remove a mic from the board and remote locate it somewhere.

There are "shock" sensors for that. Your local audio or auto parts store should carry bars of LED that flash to the bass. Just use those and use a new speaker terminal to wire the light. I'm guessing is a Band Pass box since you wanna put the lights "inside".

i know some people have said that this method aint safe but what i did is connected them directly to the amp speakers. it always worked good with me until i sold that car...i dont know if because i had around 8 or 9 LEDs made a difference than just 1 or 2
