hai, Here is the solution. when u cut the PCB from both sides u will find 4 cables i.e. green blue yellow and a copper wire coming from woofer and 3 cables white, red, yellow coming from audio lead. connect the green cable to copper cable and yellow to blue coming from woofer. Now take white cable coming from audio jack.connect this with yellow blue cables of woofer. Now attach Red and Yellow, connect these to green and copper cables of woofer and enjoy. if problem persist then make experiment to make interchanges with red white yellow coming from audio lead to the 2 sections of woofer side. woofer connections green/copper and yellow/blue remain same.

Here are the Pin outs for different mics that will work with your radio. If a wire is not listed then you cut it off. It's best to keep the wires as short as possible no longer than a half inch is suggested. Normally the Cobra pin out is standard for most radios.

Hello,
Here is the wire diagram for several common mics in relation to a 4 pin CB. Most recent 4 pin CB's such as Midland, Cobra, Connex, Uniden, etc can use 4 pin mics. The wiring is actually depending on the mic rather than the CB so long as the CB's are 4 pin as well. Once you go back to late 80's the 4 pin design was a little different. Anything new it is simpler.

3-pair version of (red/green, black/yellow, white/blue). But the first two pairs are not twisted
So it becomes green/red, yellow/black, & white-black/blue. G1/ R2 /3Y /4B /5*Blk/6Blue (this is what you physically see on the other RJ11 connections since this is a data connection and not a phone connection it should be a straight-through instead of cross-over connection.
These RJ 11 PINOUT assignments may be incorrect because they apply to a color camera instead of B/W

RJ11-e starts off like a RJ45 Stranded Patch Cable.
The color code used in stranded patch cables is different from solid-conductor cables. For NorTel Digital Patch Cable (DPC), the coding is; Pair 1: Green & RedPair 2: Yellow & BlackPair 3: Blue & *Orange White\Black
*In Pair 3 the color coding is Blue & Black instead of Blue & Orange and the pair is twisted so that the Blue wire is the 6th pin instead of the 5th pin.
