Sonos Connect Amp and Speaker Volume

I just got a connect amp and wired it up with a pair of outdoor Polk Atrium 4 speakers. After I got everything installed I went to play some tunes... I had to have to volume to about 50% on the slide bar on the app before I really heard any music out of the speakers, and even then it wasn’t very loud and I was standing right next to the speakers. If I had the volume up to 80% or higher it got closer to a normal listening level, but didn’t leave much room for advancement. I typically listen to my play 1 or sound bar between 30-50% unless we are having a party.

I’ve read other reviews where the Sonos amp and a pair of outdoor speakers is blowing their neighbors away, I don’t feel like mine are getting that loud. Do I need better speakers or is it the amp?? I bought the amp open box excellent condition from Best Buy, I just want to make sure something isn’t wrong with it before my 15 day return window is up.

Any feedback would be appreciated!

    Thanks Jeff. My kit didn't come with anything to connect to the line in. I just bought speaker wire and connected the speakers to the Connect AMP.

    In that case you shouldn't need to adjust any settings on the line-in menu. Are you having any trouble getting the audio on your speakers working properly?

    I don't hear anything on the AMP connected speakers (ourdoor) unless I have the volume on them set to over 50%, and even then, they're fairly quiet. Anything grouped to that, at 50%, would be very loud. The sound is clear, not fuzzy, it just doesn't match up with what the volume is set at.

    That sounds like an impedance issue of some sort to me. How many speakers do you have connected to the CONNECT:AMP? Can you submit a diagnostic report with the CONNECT:AMP playing? Reply with the confirmation number and I'll take a look.

    One pair (a left and right speaker), are connected. I will submit the diagnostics later tonight as I'm not home now. Thank you!

    Thanks for sending in the report. I'm not seeing any issues with the amp, or any volume clamping. Is there a volume setting on the keypad that you can adjust? Are you able to bypass the keypad and see if the audio is still distorted?

    Sorry, I'm not following... what keypad? Audio isn't distorted, just very quiet. I can't hear anything from the speakers unless I turn up the volume on the amp or in the app to higher than 50% for my "patio" room. 50% inside is LOUD.

    I have the same problem with my Connect:amp i'm using for wired outdoor speakers. I submitted a diagnostic report 167150526. The sound is almost muffled and I need to have the volume over 50% to be decent listening. These are existing speakers that could really crank with my previous Denon home theater receiver. I need to purchase another Connect:Amp for in the ceiling speakers but wont unless this sound issue is resvoled. I'm using a Beam with subwoofer and surrounds in my main room and it's good!

      alicooks, not sure which of the multiple problems above you are having...

      This poor topic is so confusing with multiple folks posting different problems I can't keep it straight who has what problem and what they have tried. Even Jeff is confused at this point, one of the early posters had a keypad, others don't. Some are trying to use the line-in and others aren't.

      Are you using a keypad controller? Is this a line-in or streaming problem?

      If it is grouped and streaming is the Connect Amp grouped with the Beam or is it setup as the rear channels? If it is grouped have you expanded the volume controls and adjusted just the Connect Amp control?

      If it is a line-in issue have you tried adjusting the line-in sensitivity?
