How to wire LED Strips to car audio amplifier!
Be careful when you DIY any project at home, especially wiring LED Lights to your AMP. It is always best to consult an expert at your nearest Audio shop before you attempt to hook up led lights to your amp!
We surfed the net to find information on what others did regarding wiring LED strips to their car audio amps or sub-woofers.
- You can wire your LED Strips directly to your subwoofer wire ports.
- You can wire your LED Strip by connecting the Negative on the Negative and the Positive on the remote wire.
As mentioned below in the thread: “the issue with that is you will begin to start drawing too much current from the remote wire output on your HU. It’s not too big of a deal for a small chain of LEDs, but once you start hooking up too many things to your remote wire from your HU, you’re bound to cause problems, and possibly even burn up your HU. “
can i wire my 4.7inch strip into my Amp????? By putting the negative on the negative and the positie on the remote wire??
Just hook it up like you regularly would. Since the amp is already hooked up to the radio with the remote wire it’ll only pulse with the bass.
Yes, you can, but the issue with that is you will begin to start drawing too much current from the remote wire output on your HU. It’s not too big of a deal for a small chain of LEDs, but once you start hooking up too many things to your remote wire from your HU, you’re bound to cause problems, and possibly even burn up your HU.
I just checked Phil’s description of the LED strip, but it doesn’t say its amperage.
Your best bet would be to run a simple relay. You could tap into the main power wire going to your amp, and run a relay. This then gives you the ability to run a bunch of lights off of your HU, without hardly drawing any power from it. The relay will have 5 prongs, but you will use four. One will connect to your amp power wire, for constant power. This is where it will draw the power to run your relayed electronics. One will connect to your amp ground. One will connect to your HU wire, as a power selected source, and then one will connect to all your electronics that you want run off of the amp power wire, only while the HU remote wire is hot.
The only way the LED strip would pulse with the bass, would be if you had it hooked up to the speaker output of your amp. However, that power is AC, whereas your LED strip runs off of DC. It may actually work and pulse for a SHORT while, but then it will burn out very quickly, or just not work at all.
The remote wire from the HU does NOT give a “bass” signal. It only gives an on/off signal, telling the amp whether or not to turn itself on, or off. It has NOTHING to do with the “sound” coming from it.
I had some lights in my trunk and I wired them into the constant power (From the battery) and of course the main ground, then had a switch on that main power.
If the goal is to hook the LEDs up such that they “pulse” with the audio, aren’t there sound control modules that are specifically designed to do just that? If so, I’d assume that such a device would be safe for 12v appliances that can handle dimming/undervoltage (like LEDs). Someone please correct me if I’m wrong, but I can swear I saw something like that not long ago…
