I have a Q Bomb box with two Memphis speaks 400/800. My amp is 1250 or 1200 Zeus elite hifonics. I am not using an after market radio. My car is a 2010 nissan rogue. I checked all the wiring. No speakers are disconnected. No issues with ground or battery wires. I do however have a converter box connected to my passenger speaker. I have yet to check if thats the issue. Just looking for some input or insight on where to look, without wasting time.}
