Subwoofer wiring - M&K MX5000

post #1 of 4
Thread Starter 
I lost my previous sub a few months back (not sure what happened, but repair cost was going to be more than the sub was worth), and had not gotten around to replacing it yet. It was an old Polk, and because of the way the room was wired, it was set up using 2 pairs of 16 gauge speaker wire to a Denon AVR-887 receiver.

A family member mentioned they had an old sub sitting in the closet which they were no longer using, and would give it to me for free. It is an M&K MX5000 THX II powered sub. I'm not very adept at the audio side of home theater, so I have some questions about the wiring. My receiver is a Denon AVR-887 which has speaker wire sub outputs. The M&K MX5000 has RCA inputs labeled "Left/Mono" and "Right". Is it possible to wire this somehow with speaker wire on the receiver side and RCA on the subwoofer side? How would I go about doing this?

Thanks for your help!

Welcome to the forum.

It looks like your receiver does have a standard RCA subwoofer output. Connect to the left sub input with an RCA cable. Be sure to run through the Denon setup and turn on the sub, set levels, etc.

Thanks for your post, and your input. I do see now that the receiver has an RCA subwoofer output (I original thought that was a multi-room output, or some such).

However, I am still up against the fact that the in-wall pre-wire that was done on this house is using 16 gauge speaker wire. Can I simply cap each end of the 16 gauge speaker wire with an RCA plug, and everything will work fine? I assume a sub cable is just a passthrough? (no crossover?).

Thanks again for the help.

No. You would need to use shielded cable. Speaker wire cannot be used for a line-level connection. Standard RG6 coax cable works well.
