hello all, hope someone can steer me in the right direction. I bought a pyramid brand 1000 watt speaker system from jc whitney. It came with no instructions. I am using the stock radio in the car. I disconnected the rear speakers in the car, and lengthened the wires, then ran them back to the new speaker system. now the front door speakers are louder than the new speakers. I know I did something wrong, I just don't know what it is. I get good bass, but it is low in volume. they are ten inch speakers, five hundred watts each. how do I bump up the volume? do I need an amplifier for the radio? or do I somehow amplify the speakers? any help greatly appreiciated. thanks.
