Hey, I know I risk looking like a complete idiot by admitting this, but I'm putting 2 12" Streetglow LED strips alongside my sub box. The only installation instructions say to connect the ground and the power to their respective sources. What I want to do is make them flash to the beat, much in the way my old Duals did. Can I hook them up to the speaker terminals on the sub box where the wires from the amp are hooked in? Or will this break the LEDs/underpower the subs? And if this isnt possible, does anyone know how to wire them to my amp? Thanks.

You have to also hook the power/ground from your amp into the speaker terminals along with the LED strips power/ground wires.

haha yeah im a little confused by that. what i mean is, should i put the speaker wire, which is coming from the amp, into the terminals on the box, AND put the LED's ground/power into the terminals too?

Put your positive led wire into the positive speaker input along with the positive speaker wire.

Put your negative led wire into the negative speaker input along with the negative speaker wire.

Easy as that.

no, i dont see that as working. if its supposed to be powered by the car then plugging into the terminals on the box shouldnt work.

(car is dc power where as the amp puts out ac power.)

Well, I believe the AC would make it a) flash to the beat and b) my duals worked with this wiring configuration, but im using independent lights this time that arent built into the box, thats why i ask

It will work, trust me, when you start cranking the volume up, they flash harder.

This.

LED's generally run off DC, AC is quite different. My guess is they'll all glow REALLY bright for a very short period of time.

Many general auto parts stores sell very simple control units for lights.

Many come with on/off/bass modes. The "bass" mode either works via built-in mic or vibration depending on the unit.

They usually cost 20$. Just hook it up to power and ground and run the lights through it.

Safe and easy and gives you complete control over your lighting. Hooked this up in a vehicle for interior and exterior strobes and constants.

Alright thanks everyone I tried hooking it up to the subs directly and it worked...I'm keeping it that way until the music module is back in stock, I'll switch to that after.

It is quite likley you are going to burn them out over time, as they are only ment to see around 14volts, and your amp will peak more around 35volts...

If you are going to leave them hooked up that way I'd put a 5w resistor in series with them... If you measure the DCR of the LEDs you should be able to figure out what value to use...
