How to hook up old subwoofer that has speaker wire

My grandfathers receiver went out so I went ahead and ordered him a new Sony receiver to replace what he had. He has five speakers and a sub. I was able to wire all of the speakers up without a problem but his subwoofer has speaker wire running from it, not the regular subwoofer wire with RCA plugs like they use now. Is there a way for me to splice a new cable on the speaker wire with an RCA plug? I'd like to avoid buying a new sub since he's 93 and isn't exactly looking for big bass coming from his system. I went to Best Buy and called Crutchfield and neither of them could really help me out outside of selling me a new sub.

Yep, you can just buy a male RCA connector.

No, you can't just splice a wire.
The sub you have is an unpowered sub, which requires speaker-level signal, whereas the receiver only outputs line-level signal.
1. Buy a new subwoofer that accepts line level input (pretty much all do except ones that come in a package deal)
or
2. Buy an amplifier for that subwoofer
or
3. Go without a subwoofer

Speaker make and model would help as well as pics of the tie in on the sub.
Many older subs were designed for you to wire the speaker outputs into the sub then out to the speakers from the sub with a low pass filter feeding the sub it's signal and the signals above this frequencies passed in to the speakers from the subwoofer.
At least that's an old mans recollection.

Thanks. I guess I'll just keep my eye out for a decent low priced powered sub and give to him for Christmas.

The RCA plugs send a signal to an amp. His old sub wasn't amped, so it just had speaker wires going to it. It used the internal receiver amp. If the new receiver has a dedicated subwoofer speaker wire output, you could use that

What is the make and model of the current sub? However, with 93 year old hearing I doubt he can tell the difference with or without a sub if it is properly dialed in.

I got a 12" polk sub on amazon for under $200. Thing bumps. When there is an explosion the whole house shakes.

I had this exact same problem yesterday at the in laws.
Bought one of these on Amazon Prime for them. I have one at my house and it is decent for the size.

I hate those old Home Theater in a Box setups. Crappy speakers, amps, no outputs, etc. I guess most have moved on to sound bars.

So you just hooked up an RCA cable to the input and it worked no problem?

Powered subs have RCA inputs which would match the output on the receiver.

Seems like a good spot to tell this story on my Dad. He was always into car audio. Until his latest vehicle, he always swapped out the factory stuff for aftermarket. And he helped me and several of my friends when we were teenagers and wanting a booming system. But when he was in college, one of his buddies needed some help swapping a head unit and some speakers. There was this big box in the back, and he told the guy there was a subwoofer back there, and he could hook it up if he wanted him to. So they got it all hooked up, but no sound from it. Checked the connections, tried it again, and realized it was some box with a heater in it. It was blowing hot air.
