It's three times louder than eleven with a bit to spare which is great for listening to "Heavy Duty" by Spinal Tap.
I've wondered where that arbitrary upper limit originated as well. I have a Tazer Mini and it does not allow for changing the radio volume, at least not that I've found in its menus.
More volume will increase the output voltage and create more distortion, assuming thereās any headroom to even push into. Better to increase power (amplifiers) or use more efficient speakers.
So been there done that. Used to have a JK with infinity and easy upgrade was to replace the HU. We get her a ā21 JLURD and Iām using my Spotify account and wondering why Iām running out of volume knob. FF to me getting a ā22 JLURD and Iāve planned a replacement HU and speaker upgrade. Nothing seems to make it better until I accidentally switch to FM. Whoa, this sounds much better. Whatās going on. Seems the factory Alpine needs more signal from your source. I maxed out the quality settings on Spotify and voila, better sound quality. I ended up down the rabbit hole of a Quart Stage 6 on mine but on hers I only replaced the dash speakers with an extra set of Quart dash speakers and that made a difference. If I were to do it again, Iād just go with two pair of kicker dart speakers. A pair in the dash and a pair in the soundbar.
