Here is a quick DIY to bypass your factory amp in the rear of the car.

First things first, you will need the following to do this.

wire cutters

saudering iron (not needed but reccomended for a clean install.

electrical tape or heat shrink tube

1) Disconnect the white clip in the back of the factory amp. The amp is located underneath the rear shelf in the trunk. It's a bit tight to get in there but get used to it because you will be there for a while. My amp looked like this (1A) but I've heard they come in various sizes. Use your common sense here and you will be able to find the right one.

2) Next, we will be cutting the wires one by one on the back of the clip and attaching them togethor (DONT DO THIS YET!!). Now to attach them, you can sauder or twist them or use butt connectors... whichever you feel like doing. But make sure the connection is solid and won't come apart.

Refer to this picture for the following steps!!

Now make sure your clip is facing the same way mine is. Look carefully at the notches in the picture and the direction of the holes. THIS IS VERY IMPORTAINT! Also I would suggest doing this 2 wires at a time, so you dont loose track of which wires are which.

3)First two wires to cut are the numbers 1 and 3. Cut them, and sauder the ends togethor. Don't forget to put the heat shrink on before you sauder.

4)The next two wires are numbers 6 and 8. Again, cut them off at the back and attach them togethor in your chosen method.

5)Next two wires are 2 and 4. Cut them, attach them togethor.

6)The last two wires are 7 and 5. Attach these two togethor.

You should have a few wires left over but we are only concerned about 1-8. Don't worry about the numbers 9-12. Just cap them off so they can't touch anything.

If you followed these instructions correctly, your amp is now bypassed. Have fun listening to music through good speakers. :-D

    • Hope you aren't too sore after that one, might take a day or 2 to notice yet and I guess it is a loooooong drive home. On the bright side, tube frame front end is a thing at superlap, right?

    • The chart of front pressure to rear pressure (with one being on the x axis and the other being on the y axis) is not a straight line on a typical proportioning valve. At lower pressures there is a straight line with one slope, and at higher pressures that changes to a lower slope. That creates a bend in the line at that pressure, called the knee point. If you do not change the proportionng as the pressure gets higher, you will suffer excessive pressure (at one end of the car or the other, depending on which way you look at the proportioning action) and then get lockups at that end. The HFM BM57, from my memory of previous discussions, is based on the BM57 from a different car (to a Skyline), with a different requirement for the location of the knee point and the distribution of pressure front to rear, and so is not a good choice for an upgrade on a Skyline. Here's a couple of links to some old posts, one from here, one from elsewhere. A lot of it pertains to adjustable prop valves, but the idea is the same. There are plenty of discussions on here about this issue from al the many years of people wanting a cheap/accessible option. https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/ https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/  
    • Yeah dunno why johhny posted that here with no context, just post on FB/insta bro where he put it up?  Laine had an off at T4 during Thurs prac, he's ok, car is less than perfect, they are done for the weekend, he can fill in the rest. Bando also binned it like 100m up the road.   
    • I feel there must have been a FB/insta post and the weekend did not start well at all I hope everyone is all okay
