too much for me to read...double check and make sure all your pos and neg wires are right from the deck to the speakers...if one side is crossed up you'll get sound but with lack of bass because there will be cancellation. This is 99% of problems from lack of bass after installing a new radio system when comparing to stock

Your speakers are out of phase.
