Hello! I have no knowledge on passive speakers whatsoever and I bought these speakers on Black Friday for $120 and I thought it was a good deal, though I did not do my research on it before I bought it hence why I'm here. I currently just want to have good and crisp sounds from my PC since the reason why I bought these is because my monitors do not have built in speakers, so I thought the idea of bookshelf speakers were a good touch. I've been asking around multiple audio shops and so far I am running the speakers > power amp > audio interface > PC motherboard. I am using banana plugs for the speakers and they're plugged in to the back of my power amp (I double checked for loose connections and there are none) I then used RCA cables from the power amp to my Behringer 302usb audio interface (picked it up for free so I wanted to plug it in as well). Originally I was just going to skip the AI and go from the power amp to my PC but no audio was received or is very faint, (RCA cable to a single aux plug end). With everything connected, I am so to speak not getting the full power of these speakers even though I can hear some audio still, just with a lot of static. I was told that it could be loose connections with the cables but everything is tight. So my conclusion is probably I plugged it into the wrong place or my PC motherboard doesn't have the correct inputs. Does anyone know what could be causing these static noises? As in whenever I play any type of audio, there is a lot of static noise and sounds like a really old iPhone speaker (all my mic volumes are off or set to 0) I also have a sound card for my PC I could use but I do not know if that is necessary (Sound Blaster Z). Thank you! I don't know anything about audio so please don't bash on me Here are the links for the products I am using (I'm just trying to get simple audio from my PC): https://www.amazon.com/gp/product/B003OELGGG/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1 https://www.amazon.com/Behringer-302USB-Premium-5-Input-Interface/dp/B005EHILV4/ref=sr_1_15?dchild=1&keywords=behringer+302usb&qid=1606799801&s=electronics&sr=1-15-catcorr https://www.klipsch.com/products/r-51m-bookshelf-speaker https://www.amazon.com/dp/B07HCY7K9L?tag=pcpapi-20&linkCode=ogi&th=1&psc=1
