For anyone with an iSimple, is your volume low? I have an iSimple ISHD571 and I have to turn my volume up to or close to 40.

 

Try turning the volume up on your phone as well. If it's low that's probably why volume through the iSimple, or any other similar device is like that.

 

It could easily be the device which is giving you volume issues. When I connect my Galaxy S6, it needed to be at 33 for good volume with the windows down at 45-50mph. When I'm listening to the Nexus 7, 24-25 is usually all it needs. That's windows down at 70mph.

 

Im having the same issue. Im a professional car audio installer and I put a isimple IS32 in my 05. Regardless of the phone I need both volumes maxed out and its still not nearly as loud as the tuner. My solution will be to install an Alpine power pack model KTP 445 (about $150). This small amp has a front and rear gain adjustment and allows you to increase volume to the speakers. The downside is you would need to turn down the volume if you switched between Isimple and other sources.

 

Well I don't suppose it would just be not pushing the connector in all the way, would it...? They are quite tight when only halfway in you know
