Hello Everyone.
I have a six year old Pioneer SW-8MK2 active mono subwoofer that I purchased from here a while back.
The built-in amplifier gave up the ghost and there are fried components burned on the circuit board.
Knowing I would spend more than I wanted to repair the amp (cheaper to buy another used one on CL), I removed the amp boards from the metal cover and wired the subwoofer speaker wires directly to the left channel of the speaker-level inputs.
Now I have a "passive" subwoofer.
My AVR is a typical Yamaha HTR-5650 with the (now unused) subwoofer RCA output and no subwoofer speaker outputs.
I want to connect the subwoofer directly to my "B" speaker L and R terminals to get the low end sound back.
I have a cheap low-pass subwoofer filter to install inside the box to take away the highs.
What I need to know is how to wire the AVR L and R speaker channels to make them mono into the subwoofer's single channel to avoid burning anything up.
I heard you can solder resistors to the L and R red wires and they combine them after the resistors.
The black wires just get combined together.
The subwoofer speaker is 8 ohms and can handle 100W of power.
The AVR puts out 80W per channel, according to the specs in the manual.
What value of resistors should I use and is this a cheap and safe way to get use of my subwoofer back?
Thanks!
