Internal wiring schematic for a JBL 4311 WX-A

I am looking for a JBL 4311 WX-A speaker internal wiring schematic? More specifically, the internal wire color codes that go to each original driver's positive and negative terminals. The factory wire color code inside enclosure is as follows: Woofer = green and green/blk stripe; Midrange = white and white/blk stripe; Tweeter = yellow and yellow/blk stripe. Which wire color code goes to which terminal on each respective driver?

The conductor xxx\blk is the minus or black( from speaker) the outher is positive\red pin from speaker) the woofer is bigest speaker inside is connected on the crossover at low output, tweeter at high output, if you connect wrong you can burn speakers and crossover, you can test with very low volume on amplifier.

1st connect low to woofer, it only her low freq below 500Hz like drums and bass, if connect on med out the speaker is working as handpocket old radio audio. if connect on high the speaker is like no audio out. (the woofer take about 60-75% of amp power).

2nd connect the midrange at mid output you can listen to human voice cristal clear. if connect on high output you listem like esteric female shouting.

And connect the tweeter at the empty output

Take particular attention on polarity terminals, if you exchange the polarity you have a moofle sound traped inside of speaker, and some structered box noise who may open the box panels in future.

My JBL DCR 600 head unit keeps cutting out after I turn the power on

try checking your speakers and/or speaker wires for grounds or shorts. If they check out fine, you have an internal problem with the amp, more than likely blown transistor(s).

I need a schematic for a uniden pc 78 elite cb radio

I will assume you have also looked for the schematic as a Cobra 29ltd which is the same radio----Check the internal speaker with a meter first and also examine the external speaker jack which will cut the inside speaker off.

Lastly a microphone with a broken wire in any area will kill receive audio.

HOW TO REPAIR A DAMAGED JBL PB12 it just stopped working, somebody told me it was unfixable due the part are very hard to get I guess the internal amplifier got broken

There is a quick way to find out if the parts are hard to get. Look inside a make a note of the IC and Transistor numbers. Don't bother with the resistors and caps. Put the numbers into Google and see what comes up.

I installed a sony x plode amp in a 2005 corolla which had a stock six speaker amp by jbl which came with car i also bought a jensen hd dvd radio i installed radio but need a wiring schematic to by pass...

If I am going to have a car and do a lot of audio installations, I try and order the manual for it. The manual usually has a full wiring schematic. You might call down to your local Toyota dealership and see if they can help you with the wiring schematic.

Also, you could just run new speaker wires. I know its a pain, but that is another alternative. With that being a newer car though I can understand not wanting to start tearing off internal moldings.

Bloon Fuses!

You don't need schematics to replace the fuses.
Open the speaker unit by unscrewing the back. The fuses are located near the on/off switch assembly. Replace them and screw the the unit back together.
To avoid blown fuses, try lowering the volume.
