Review on 🔊 RoadPro RPSP-15 Universal CB Extension Speaker with Swivel Bracket, Compact Size 2.75" x 4.5 by Troy Caldwell

Some reviews say they are not as loud as they were hoping. I beg to differ. I have them under the dash for both CB and ham radio and I don't even have to turn the radio halfway to hear them loud and clear. These things are loud. Now they are not noisy when connected to a cellphone. I think it depends on the performance of the device. But for my radios they rattle loudly. Just to see, I rolled down the window and turned on the weather panel. I could hear it across the street. Very compact and fits anywhere. All fasteners are included.
