When I first started using my my scala q3, I was thoroughly disappointed with the sound quality. I could barely hear my music on the freeway. I bought these speakers in a last ditch effort to avoid hardwiring new speakers in. I'm glad I did! They're a lot louder & clearer than the stock speakers. The sound quality isn't perfect, but they're a definite improvement. They aren't Bose by any stretch of the imagination, but they sound much better than stock. If you need a cheap and worthwhile upgrade for your scala system, this is it!
I wear a Daytona skull helmet and it fits great with that. Sound quality for phone calls is excellent. Audio for audio files is just okay. Works great for me as i like to ride distance and this keeps me rolling when a phone call is necessary.
This unit is good as long as riders are within 1/4 mile or so. Maybe better on open flat but hills and other riders between radios limits use. It's a lot of money and additional cost or time to install. J&M is a great customer service company, but this product is very limited.
Exceeded my exceptions. The range is better than I thought it would be, which is a pleasant surprise. The sound quality is very good and loud enough to hear over the rumbling of my Harley. When I speak to people on the phone that can't believe I'm on my bike. It really eliminates the back ground noise. Would highly recommend this product.
