50W - 100W Amp for Subwoofer

Anfield · 12th September 2006, 09:13 PM

Hi Guyz

I'm very interested for the simplest circuit I can find to drive a
subwoofer 100WRMS. Preferably a circuit with PSU design included.

I found some around but I don't know if these we suited for a sub and they didn't have the psu design included

Thanks for any help

Its not really clear what it is you want excactly - only schematic or kit, only amp or with crossover, EQ.......?

Hmmm a schematic rather than a kit, a schematic including PSU, crossover, amp and simple EQ for a 100WRMS Subwoofer.

Would like to build one myself. Simple designs are preferred :-)

Thanks

Hi Anfield,
Once you have a PCB, they are all pretty simple to put together. There are some excellent projects on this forum as well.

how about a parallel LM4780? 100ish wpc into 4 ohms. really simple.

hi mate....

thks

sure, they're available through audiosector.com or chipamp.com...for driving a sub you may want to add some bigger electrolytics to the PSU but that's not hard.

Hi,
find an amplifier schematic you like and add a PSU to it.
The PSU can consist of just the transformer, rectifier, smoothing caps and connections.
