How to hookup old subwoofer to new sound bar?

1,114 511 December 3, 2019 at 08:12 AM
So I have a close to 10 year old sound bar and subwoofer. It's a Vizio soundbar and a separate brand external 12" subwoofer. I don't like the cheapo subs that come with soundbar kits...not nearly enough bass. Anyways, the subwoofer is only able to hook up via the RCA cable; no wireless or any other options. This older soundbar had the RCA subwoofer input jack...so it worked perfect all these years.

My soundbar is starting to crap out; it constantly needs unplugged to reset it to turn on again. Otherwise it won't turn on with the TV like it always used to (sound bar connected to TV via optical cable). I've replaced the optical cable and that didn't change anything. It will just act dead; won't even respond to pushing the soundbar buttons to turn on until I unplug it to reset it. This is a giant pain since it's hung on the wall and I have to remove it to unplug it.

Shopping for new sound bars, I haven't seen any that still have the sub RCA input. I really want to keep my current sub...what options do I have to hook my RCA sub up to a new soundbar that doesn't have RCA sub inputs? Is there some kit I can buy to convert my sub to wireless to pair with the soundbar? Is there a way to hook the sub directly to the TV? It's a newer 65" vizio TV. Thanks!

No new sound bars work with any external sub. Either buy a new soundbar with a sub or buy a receiver and separate speakers for your fronts.

Well that sucks...is that just cause they have all moved to wireless and want to sell their own kits with subs included?

Soundbars are just so convenient and slim compared to huge receivers and speakers. Do any TV's come with sub input RCA's? It's a self-powered sub...so no need for an amplifier.

I don't think that would be very likely, most people that care to run a sub run a receiver as well. Your desires here are pretty niche.

I am all for doing your own research, you might be able to find a refurbished older soundbar, or one that has it. Look around a bit.

I noticed on the back of my TV it had a dual RCA labeled audio input. What would that be for? You think it would work for hooking up just my sub with single RCA?

RCA input could be used for say a VCR or older gaming system audio, etc. If it's an input it won't help with your subwoofer as you need an output.

Or you could get some powered speakers instead of a soundbar and hook up your sub, probably sound better.

If your TV has fiber optic output, you might try this:
