NEVER, NEVER, NEVER connect anything other than speakers to your amp. That is the WORST thing you could possibly do. An amp expects a resistive load. When you put diodes (Light Emitting Diodes) across the outputs, you're asking for trouble. Not only can the LEDs burn up but they can also short out the amps outputs!!!!
@sparky3489 So yea.. I didn't hook anything up to my amp... in fact, I never didn't even have an amp installed when this video was made.... don't know where you got that idea from
@mcdholdem NO speaker will work without an amp whether it be an aftermarket amp or the one built into the head unit....and I quote, "All I did was pick a speaker to hook up to" ergo THE AMP INSIDE THE HEAD UNIT!!!!!
@sparky3489. I suck at electricity stuff, infact, I got my A's in the subject by discussing hockey with the teacher. That being said, wouldn't it be possible to bypass that problem using resistors?
@SoPlEoReD Theoretically, yes you could. However, what size would you use?
An LED is a DC device, an audio signal is varying AC. The current limiting resistor used for LEDs in a DC circuit is easily figured since you know the constant voltage you are working with.
In audio, despite the fact it's AC, it also varies in voltage depending on how loud or quiet the music is. There is no constant.
@sparky3489 for people that want flashy lights, i always reccomend getting a cheap pos amp with LPF. and to at least get a 2 or 4 ohm resistor to put in with each light. but you're right, never run it along with the amp powering your subs. thats the shit worth protecting.
@LordPS3 2 or 4 ohm resistors are WAY too small for the amount of current even 25 watts can deliver. That will surely blow out an LED. Even at 25 watts you need a 560 ohm resistor for a standard red LED. Besides, a MOSFET transistor is only a few bucks which is a lot cheaper than some pos amp.
So pretty much in a nutshell I wanted to do this for a little money as possible.. lol so I can guarantee you this isn't the most efficient, but I like it just fine. All I did was pick a speaker to hook up to , I chose the back right one. Then I spliced in a wire that then runs to a simple SPST switch (on/off). From the switch It went through about 8-12 xmas lights before returning to the speaker wire. It is all in series.
@DaHandy I did notice btw that you need to cut the wires on the xmas lights to make them go from parrellel to series or else they wont work. The lights wont come on at lower volumes because there isn't enough power going to them. Hope this helps, any questions let me know
@sparky3489 lol totally forgot about that. Good one! Lol

It's just not worth it.

@sparky3489 you get the point though. put in resistors to make sure your amp don't break. and who the fuck would hook up a single LED to an amp? lol

@LordPS3 The same people that would buy an amp instead of a cheap MOSFET lol.

are the LEDs hooked up to an amplifier?

@canes023 nope, they are xmas lights too btw... the blue lights are led tho
