Poke around the web site as there is a partial 500W sub amp kit available there. Watts are pretty cheap thses days, so you won't save much money over an Asian OEM unit, like P.E. or apexjr sells. The {I built it myself} factor is definatley cool though.

One can hardly help but note, Bill, that you also neglected to tell the OP how to do what he wants to do... 😉
Another way to go is to search around here for LM3886 -based amplifiers. Bridged or parallel, these are cheap and pretty good amplifiers with a bonus feature of being VERY simple to build.

Hi Cac liu,
Do you need the design of the power amplifier?
or
Do you need the design of the filter before the amplifier so that it only sends bass signals to the speaker?

I means the circuit ,how to make the general audio to the only bass sound?
I'm a beginner,and my English is poor.
Thank you !

Hi,AndrewT:
what I need is the low pass filter.Do you have the circuit of this unit?
Thank you very much for you reply!
If you have it ,can you send it to me?

Hi Cac liu,
try here; http://sound.westhost.com/qb5align.htm
fig 3 shows a 2 pole filter and the rest is all the maths you could ever need to shape your bottom end response.
There is a xover thread running now with boards available, Moxlite has space for 2 bandpass filters (choose from 1, 2, 3 or 4 pole rolloff) and 2 equalisers for other alignments and an input buffer (no ouput buffer). If this is inside your amp box with very short interconnect then an ouput buffer is not required.
It could be converted to give a hi pass output to the satelite and low pass to the bass. In this case keep it inside the satelite amp box.
