There are hundreds throughout the internet...
Ask if you need more support to pick one of them.

apex,
what are frequencies of the two x-over?
from pot zero to ten range,
can this go cover 150hz
sorry for vertex wrong posting
X-over frequenies are from 80Hz to 250Hz,
Regards
What this Auto near power input for ?
'Auto' is for amplifier auto-start circuit if audio signal is present to x-over input.
x-over
you post 2 kinds of x-over is the other one also 80hz - 250hz?
please give me idea how to convert pots to variable selector this maybe different resistor in every turn,but i need you to guide

This is FET for mute amp when power amp on/off, you can use any similar FET or use amp without this mute circuit (without FET).
Yes this amp is for bass guitar.

thanks, then how to wire it?
i mean from tone cntroll to pwer amp.

Only wire on this amp is from transformer to pcb and from pcb to speaker, all other is on pcb.

Making X-over
I am building X-over by "Apexaudio". Work in progress waiting for few components.
Ones complited will test this with my Subwoofer and then will share my experince about this.
I hope there will be no problem if i leave the "Auto" pin Not connected with any type of auto-start circuit.

active crossover
Can you share schematic and PCB on your active crossover pls
hi apexaudio
greetings my active crossover
thanking you

well,..i will try it,just remove the FET transistor,no added wire or any things else.

No problem to use x-over without auto-start.

Just remove the FET.

Thanks Sir.
It's finished. Will test it on Sunday...

Apex Sir.
This Sunday I tested your crossover circuit with my subwoofer.
SUB = Sealed 15” x 15” x 18” box with cheap 12” car sub-drive and 400W power amp.
I have tried many sub pre-amps circuits till date, but sorry to say sir didn’t found your circuit as good in bass as the following circuit.
Above subwoofer + this low pass circuit + input from PC (Asus Xoner DX) sound card.
Make’s every window of my room vibrates like hell.
Apex sir please have a look on this circuit and share your opinion and also I would like forum members to try this circuit and give their experience about it. This is a very few parts Low pass circuit and it’s very good too.
Thanks

This simple x-over work in range 20-100Hz, if you need this low pass instead 80-250Hz you can just use pot 2x50k instead 2x10k and sound will be same.
