Hey all,

Just finished replacing my stock jzx100 speaker amp with a kenwood 500watt 4 channel and it works great no more buzzing and whirring when i accelerate so i thought i would put up the diagram and colours i have worked out for anyone else with the same problem to use.

Now this is my first write up and the pics where made in paint so be nice

First off amplifier is located under the passenger seat you have to take off plastic covers on seat rails and then undo the 4x14mm bolts once that is done angle or lift the chair(your choice) and undo the 2 plugs under the chair the lift chair out of car for access to amp.

Undo the 2x10mm bolts holding the amp mounted and under the 14 slot plug and the 16 slot plug and remove old amp.

Now the fun starts...

14 slot plug

1 - Red with blue stripe - Remote
2 - Grey - ACC
3 - Red with white stripe - Battery Constant
4 - Black -
5 - Green - Front Left Speaker +
6 - Red - Front Right Speaker +
7 - Not Used
8- Not Used
9 - Black - ACC
10 - Blue with black stripe -
11 - Brown - Ground
12 - Yellow - Mute
13 - White - Rear Left Speaker +
14 - Blue - Rear Right Speaker +

Now out of this plug i only used 2 and 9 what i did was soldered them together so that my headunit acc wire can stay the same. I ran new remote, ground and battery constant for my car and my nesa double din dvd player has rca outs for every speaker so i can rca wire down the centre console and under the passenger seat to the new amp.

Now i stuffed up and didnt write the colour of these wires in there locations on my piece of paper i will fill it in next time but the wires in this bunch are all the main speaker and sub wires.

Speaker wire colours on 16 slot plug

Front Left + - Purple with black stripe
Front Left - - Pink
Front Right + - Blue with black stripe
Front Right - - Blue with red stripe
Rear Right + - Yellow
Rear Right - - Black
Rear Left + - Red
Rear Left - - White

Sub + - Red with white stripe
Sub - - Black with white stripe

Now i cut these wires away from the plug (left enough wire on plug incase of return to stock) soldered new speaker wire to them and ran them to my new amp now mounted under my passenger seat.
Because of the low wattage of speaker in the car stock i hooked up all 4 speaker and also bridged the subwoofer in aswell. it sounds good and i have no unwanted noises now

Now put your seat back in and clean your car of unwanted leftovers and your done.

My amp atm is cable tied to the old amp mounts until i make up a mounting bracket for it

Cheers

P.S- Always unplug battery before doing any electrical work and i recommend testing your system before putting everything back together (simple things im sure you already know but doesnt hurt to say so )

very good post. good on ya
hooking my one up tomorrow!

Brand: Metra
Part No: 70-8112
Description: Toyota/Lexus Amplifier Integration Harness

I used the above to wire my JVC KW-AVX820 up to my factory wiring harness and it works perfectly, no buzzing, no nothing.

It cost around $30 delivered from the US, so well worth the money and was a piece of cake to install, none of this wiring harness chopping and joining wires was needed.

If you want to retain the factory amp, this is the way to go.
