loudness

I just bought the uniden bc15 for my sds100. It sounds nice but the scanner itself is louder than the speaker, which is a disappointment. What are some suggestions for external speakers that go louder? I would most likely use it for both desktop as well as mobile.

Is there a way to normalize signal loudness on the BCD996P2 device? We're running the audio through a computer and then speakers to achieve normalization but it's ugly and I'd rather not if the scanner can process the function internally. Thanks
