hey
i got this woofer and a stereo setup, how would i got for mixing both signals into 1 for the woofer?
i tought about using 2 resistors and a opamp
what do you guys about this method?

If you look at this page, you will see subwoofer eq with a summing circuit in the beginning of it. The summing part should work for your application:

yes, it is the common way
2 resistors and an OP in Inverting mode
that is a nice mixer
lots of schematics on the web
it is called "summing amplifier" configuration

thanks for the replies..
any ideas for what opamp to use? i got some ua 741 in here and some lm318 i think... i guess they would suck for low freqs....

They suck most for high frequecies.Ilianh said:
But sure there are better, even for a low cost.
TL071 (072 074) is often used.
I would use some Burr Brown (TI) OPA2134 op-amps.
They are reasonably priced.
edit: typed it in wrong. these are the ones that i am using for my subwoofer active crossover.
