Hello all, if anyone can help. *I am curious, I have an Onkyo two channel from '99 or

105wpc into 4ohm so I picked up a pair of M&K 4ohm speakers used, very accurate,

not enough bass.

Problem is, I don't know if a powered sub can take the 50 or 105 wpc into it's own
electronics as a pre-amped signal and then power the woofer? *Because this receiver
does not have a pre-amp output for a sub. *Is it safe to do so, or should I look for a
good passive sub?

Any help is much appreciated, and product recommendations are quite welcome.

Hi! I would get a passive subwoofer, and another power amplifier
source, and connect it to the tape record output of your reciever, and
then connect that second amplifier to your passive subwoofer(s). That
is the arrangement I use. I have a Fisher 210-T driving two Marantz
imperial-9 with disconected tweeters and it works just fine. You have
to adjust the volume seperately--but it is worth it. The old Fisher
will reach all de way down low and watching DVD's with deep bass it
just shakes the house. A good place to find a second amp is e-bay.
They have a Fisher 175-T that would be perfect for your needs I should
think. Remember, when you are talking bi-amplification, the amount of
power needed for effective high fidelity response is greatly reduced,
sic. your subwoofer amp has nothing to worry about exept the low end--
and an old Fisher is not going to be rolled off like the dumbed down
equipment of today! Yikes and Away!
Good listening then.
