JBL MS-8 with Dynavin installed and running. Thanks for all the help here.
The instruction says if using after market HU, one should only use FL and FR for channel 1 and 2 input on JBL. But I ended up using all 5 RCAs from Dynavin. I found that if I don't do this, the bluetooth will not have sound at all.
I also turned the center volum up a few notch, otherwise the igo primo GPS won't have any sound at all
Also I noticed that if I turn the Dynavin preamp on, during input setup, JBL won't have enough signal from the HU. So the Dynavin amp must be 'OFF' for JBL to accept it.
The Kenwood XR-4S gets really really hot in the trunk. Is this even normal?
