On the lead labeled "remote turn on lead," connect to +12V with your manual switch in series.

No relay required since you will be using a switch and all of the remote turn on's will not amount up to enough of a load to require a relay.
Why bypass ignition switch? Are you wanting to leave the car unattended? The accessory position on your ignition switch is made just for this type of situation.
Just wondering.

They said that I need a relay to connect the remote wire of all my amps to to remote of head unit to avoid overheat of head unit. I want separate switch to power on/off my system as I've got separate batteries and solar charger to charge my bayberries. I can play my system without running the engine.

That's different to what you were asking...
If you are using the remote output of your HU to turn on the amps, then use the relay as per DYohn's link.
"Fan" is your amp remotes and "Remote Turn On lead" is your HU's Remote output.

Yes my HU has a remote output. I've got the idea now how to wire up. The remote wires using a relay. Only this I'm not sure how to wire up the separate switch. Is the no. 86 and no. 87 pin should be connected? Thanks

The "switch" is the 30 & 87 contacts.
That's what a relay is, a "remote switch" where a small current closes an isolated switch that can take handle higher currents (from other voltage sources if applicable).

Current day amplifiers draw so little current through the Remote wire that your radio will have no problem powering up the 6 amplifiers.

My HU is Pioneer AVH-P5900DVD
4x JBL BPX300.4
2x JBL BPX2200.1
Please can show a diagram how to connect the remote wire to a relay and separate switch to power on the system. Thanks again and sorry to keep asking again as I am not very good at this.

Unfortunately the best I could do would be similar to the linked diagram and maybe showing the ground/earth symbol from #85 as being connected to GND or the battery -ve terminal, and with the name/label changes I gave previously.
It sounds like you want a physical wiring "picture" that shows all the plugs and wires and joins etc.
Maybe someone else can do that.
Otherwise I suggest you find someone that can, or find out what it is you still don't understand - ie, your amp terminals, the HU output pins, or elementary circuit/wiring diagrams.
I don't mean to sound patronising, but I worry that if you don't understand the answers and diagram that you have been given that you should not be attempting to wire it up. You may damage the HU or amps or even start a fire. (That's a fairly remote possibility {excuse the pun} but not unexpected if the basics are not understood.)
PS - the fuses (squiggles/waves) to each remote (fan) can be omitted. Instead a single fuse at the start of the +12V wire from the battery to #30 should be fused to protect the wiring (ie, rated equal to or less than the smallest wire rating to 30 and from 87).
