[Solved] What amp can I use with this speaker? (x2)
[Solved] What amp can I use with this speaker? (x2)
I have two of these passive speakers that I would like to connect to my TV. It really doesn't need to get super loud since I will be using it to watch tv/movies at a normal volume. My tv does have yellow/white rca audio out ports (not just audio in) as well as sigital out.
Can someone please recommend an amp and wires to attach these two with a priority on reliability and energy efficiency? I'm a noob at anything audio.
Update: I found a used amp for cheap and they both sound great!
You're viewing a single thread.
Most cheap AV receivers would power these. Look for a used AV receiver that can do 50w per channel in stereo. They're pretty common some people are basically giving them away. As for speaker wire, as long as the run isn't too long these would be fine with 20 gauge copper wire but I'd go a bit larger if you're not sure you're getting actual copper wire. 18 gauge would be a safe bet.
Edit: You will also most likely need and HDMI or optical cable to connect the receiver to the TV.
Edit 2: I'm assuming your TV has these ports but in any case, an AV Receiver will pretty much have any input you might need.
yeah, just about anything these days will work... This was literally the cheapest HDMI reciever on ebay. Hell, you can probably go to Goodwill and find one.

Yeah actually that's a good idea. Places like Goodwill very often have AV Receivers. Definitely worth a look.
If you don't need 4k and or 120hz, there are probably a million of them that people dumped when they were forced to upgrade :/
Yeah and even then they don't necessarily have to pass video through the AVR, they can simply output audio through TOSLINK or HDMI ARC.
Is there a risk if the amp puts out over 50W per speaker? If someone cranks the volume would it blow a speaker or something?
Yup!
Not really. It'll be fine. An amp that puts out 25W per speak will blow those speakers if you turn it up to max volume on a good reciever.
Yes, but most budget amps quote peak wattage, not RMS power, so even if it says 100w per channel, it might be considerably less. Ideally you get a more powerful amp and just don't turn it up past halfway. If it's less powerful then you'll get clipping when it's cranked.
My old tv does have rca output (not just input). Would something like the Fosi TPA3116 Amp work?
Edit: Disregard my post. I just woke up hahah.
Original message still stands. Yes it would work! This is a 4ohm amplifier though and your speakers are 8ohm speakers. You will not be getting the full 50w with an 8ohm load but I don't think it should matter all that much. Every speaker is different though, this looks pretty old and it might have very low sensitivity.
If you want to be sure you may want to look at a more powerful model like their 160w version.
Thank you for all your help!
No problem! Just want to add that I've been thinking about it and you really should get an amp that is either equal or higher power than what your speakers demand. While I think you should be completely fine, the right way to go about this is to have amp headroom
