EDIT....Please note that the harnesses in the below photo are prototypes.All future harnesses will feature color coded wires for easy identification.I will replace the photo once I have a new kit built with the new wire colors.

These kits will work with the base 6 speaker or premium 8 speaker systems.I can make these on demand now.They are simple plug and go harness kits for people interested in adding aftermarket amplifiers,DSP's etc and would like to keep the stock head unit.

Each kit comes with two harnesses.One provides low level preouts for 4 channels(front and rear) and a switched 12v remote out.The other provides five speaker outs including front,rear and center channel for systems with the premium package.

They will come with a plug diagram to indicate which wire goes where.No need to splice into the factory wiring at all.Simply pull the plugs from the factory amplifier,insert into the new harnesses and run the wire to your new aftermarket gear.Speaker harnesses utilize 18awg wire and low level harness utilizes 24awg wire.

Note: It is recommended to use the front low level signals to maintain factory functions such as Bluetooth,chimes,blinkers,etc.For systems with the premium 8 speaker amplifier,using this kit will cut off the factory subwoofer.

That enclosure looking real good Eric,nice work!

One thing you're going to notice is how much better your sub sounds when you get the signal from the line level before the stock amp.Getting the signal from the stock sub output wire after the amp is definitely not the best way.I've had customers who rewired their entire systems using my bypass and report back that not only did their noise go completely away but the sound quality went up as well.

The stock signal is balanced and clean,very impressive.

For now line in's from the factory sub is a temporary fix. I will be using your harness to feed either amps directly, or a eq/DSP (depends on funds availability, lol), then into the amps, after I start getting the equipment together for the rest of the build.

I did, but looks like you already found it. ;) I wish I knew why the image links in the forum aren't working. I have the pics all saved on an external server, the thread would look a lot better if they were. I couldn't find anything about image size limitations for the code. Maybe I'll tinker around with my next post over there. I've been using these vB style forums for years and never saw that. Seems like there's a lot of weird little bugs in these forums, I'm still not getting post notifications of my susbcriptions.

Here's the link for anybody that comes across this post.

Yep,something messed up here cause my build log was done the same way and everything came out here fine.

But funny, it shows in the quote, I commented out the tags so it would show in the code tag. Glad I looked here first, was just going to put up a new post of what I did today.
