12 v Sub woofer filter

kesee · 21st January 2009, 06:07 AM

Hi I have built 60W amp using TDA1562Q with 12v operating and would like to use it as the subwoofer amp.
Can anyone give me the schematic of sub woofer filter that I can use with this amp

Thanks

i dont think 60W is gonna be enough for a car sub - especially if you wana put it in the trunk!

this circuit is an active 2way crossover, but you can use the LP for a sub filter. you just gona have to change the cap and resistor values to alter the frequency (i think this filter is 200hz)

Hi Dan,

I am no expert on electronics so I am very much appricieate if you could send me a schematic of LP using TLC 074 ( single rail version) for now

As you suggested I will go for 100-150W amp later

Thanks
