few questions about hook up of fusion brain

The thump is because your drivers load after your amp is on. By wiring the brain to turn the amp on, it wont turn on until windows is loaded (sound drivers are too), so the thump will disappear.

Also if you are using a PSU like the M2, and it reboots on crank, you may want to review your wire thickness, because that should not ever happen even with a cheapo battery.

I use a $400 dry call battery. What do you mean by the wire is not thick enough? I use a
8 gauge power wire. I use the opus 150 power supply. just wondering when I crank my engine, does the radio acc wire lose power during the crank? because I have the yellow acc wire from the power supply tap into the radio acc instead of ignition switch.on the steering wheel control, are you saying there is only one wire for that controls volume up,down, next track, mode(cd,fm,am,aux)? Or there is a wire to the head unit for each?
or each button has a one resistive wire for each button? thanks. also once I figure this stuff out, is there a how to log or something on how to program with each button?

first if Im hooking up the brain for a remote delay for the amp, how would I go about doing so? second, once I find the wires on the back of head unit that controls the headunit from steering wheel, do i just tap into each wire? or is there more then that? also I have a loud thump through all my speakers when turning the carputer and amps on. and also when the carputer is already on, then I turn the key to start the car it reboots under the crank which cause the same thump sound. is there a way to fix that? thanks

For amp delay, use a relay to switch a 12v wire to the amp.

The steering wheel controls if you look behind the HU, will be most likely 1 wire resistive. So 1 more reisistor paried with the maximum resistance of those buttons is how you connect it. (voltage divider).

The thump is because your drivers load after your amp is on. By wiring the brain to turn the amp on, it wont turn on until windows is loaded (sound drivers are too), so the thump will disappear.

8awg should be sufficient, but dying on crank is not normal.

And yes 1 wire goes from all the buttons to the HU. 1 wire for all for them. It changes resistance depending on what button you press. Very common.

so basically I connect all three digital input wires from the fusion brain or just one input on the brain instead of three for each of the buttons to the steering wheel control wire?

after it die on the crank, it comes back on within ten sec. It stay on then. then when I shut the engine off, turn the key to acc it fine for like 10-20 minutes then it shut down on its own. Then boots back up after ten sec. and stays on for a while. I only tried 30 minutes. then turn it off completely, it shut down the right way then after I take the key out. The carputer stays off.

okay I called honda, found the wire, which is the green/red wire in the radio harness behind the HU. on the sheet it shows the ohms for each button control. do I have to use those vaules or can I use any resistors on the wire for each control?

Do you have a multimeter?

I do have multimeter. the sheet give me all the ohms resistances of the wire. do i just by these resistors?
