Hi all,

I just bought a Sony HT-MT300 after giving it a try at my local Currys PC World. In the store, I linked my phone via Bluetooth and listened to some music. The bass coming out of the sub was great and I could feel air shooting out of the sub with every beat. 

I bought myself one, brough it home and set it all up fine but there's hardly any sound / bass coming from the sub at all. I even tried the exact same song as I tried in the store but still very little bass coming from the sub.

I've tried the secure link but this didn't help. Does anyone know how I could fix this problem without returning it? 

Thank you
