I made a setup and installation video as the instructions could be better. The device itself is a beast! You have to understand that the lower your resistance, the more sound you get. The more sound you get, the more power it will consume. Power supply: I used a 24V 4A cable with a 5.5mm power cable lug. You can't assume you're using 12V at 2A and then say it's not powerful enough. You must have enough strength to keep everything balanced. Range: It has a fast Bluetooth connection and prevents "ringing" when connected. Range is good at 20ft as I haven't tested beyond that but may very well last longer but meets my needs. Material: PCB wood board that you can sit on. Metal plate for the top screw. all assembly equipment. Make sure your speakers can deliver 50W for maximum power. RECOMMEND: YES!
