Wiring help

[crazyxbowler 10+ year member]

I recently purchased 2 10" PG subs and they have LED lights on them. I am not good or have any knowledge about car audio at all. Can you please tell me how to wire them up in very very very simple terms?

Thanks,

John

what do you need LEDS on your subs for?

i believe you have to run a wire from the battery (could use distribution block) to the + on the power terminal for the lights, then run your ground from the - on the power terminal to a clean metal surface of your car, make sure you bolt it down nice and tight, then connect a wire from the rem+ on your amp to the rem+ on the power terminal of the light, if the power terminal for the light only has 2 connections (+ and -) then you are going to need a relay or you can connect it to a switch to manually turn it on and off

I have seen some people connect the lights for their subs to there trunk button so when the trunk pops open the lights come on

Wire to the sub's posts - the leds either are already wired into the leads, or have some odd plug that hooks up to a gay amp.

You can hook the power lead for the led to the terminals on your subwoofers, just hook + to + and - to -, they feed off the excess DC current going through the coil just like JVC's strobo woofers.

alright i have some questions now.... if you wire them to the sub post wouldn't that change the ohm load since LEDS have resistance?

2> woudln't sound quality be shiity since the leds are drinking the subs juice?

3> would the small amount of DC current in the subs wiring be enuff to even turn on the LEDS?

yes x 3

There is no excess DC current...Diodes are like a one way valve, they will only be on (conducting) during the positive humps of the AC (audio) signal. They look like they are on continuously because the eye can only distiguish flashes up to about 30hz everything above that just blurrs together. And your audio signal is usually above this.

Make sure that its the correct way to connect them though, any info come with the subs?

Most leds alone wont like the high voltages of the audio signal.

The easy way to connect them is to the power/ground on your amp.

I don't know the sceintific specifics but from from what I have read so far-

The ohm load doesn't change because the LEDs don't draw AC current.

An LED light runs on DC current, the AC current will take the "path of least resistance" and go through the voice coil, so they technically are not "drinkin the subs juice".

The amount of DC current is dependent on the volume you have the amp turned to, when playing at high volume the amplifier will put out small amounts of DC current, when driven into heavy clipping the amp will put out large amount of DC current, LEDs take very little current to light up so the small amount of DC is enough to make them glow, large amounts of DC current will make them shine brightly and constantly as your sub dies from abuse.

At the shop I work at we have a set of PG's with the LED wired to the coils and they blink with the music no prob, the amps don't complain and the sound quality is identical to having them disconnected.

Basically Ive done it , its been done and some manufactures do it(JVC strobo) with no problems. We also have customers doing it with no problems.

EDIT- Many companys use LEDS to protect tweeters from DC current.
