Ditto that. the rca output on the pyle unit is not the same as the jvc. Thats one of the reasons you are having this problem. Does the new unit have a sub output on the radio? if so turn the sub volume up. I can not find the pyle website. I'll find out more about the radio when I make a trip to my vender.
