2016 Mazda cx-3 sport I am putting in 2 sets of components, audio control lc7i a 4 channel amp and a sub and amp, I’ve located wiring harness under passenger kick plate and have found the wires, i ran a 9 in 1 to front hooked into speakers and back to dsp, but when I turn everything on I am not getting the sound or power from amp??
The amp is powered and rca to dsp. I get no sound from sub at all. I’ve read the user manual to dsp and don’t understand what’s going on. Everything has power and is on. Also do I need to use the cross overs that came with speakers if I am using the dsp? Thanks in a adVance for any help

Did you use a volt meter to verify the amp and DSP are getting adequate power? The power indicator on an amplifier or a processor is not always confirmation of power and ground.
Did you connect a known good speaker to the wires at the input of the DSP to verify that it has signal?

ok so little confused you asked did I install good speaker at input is dsp and verify sound? How do you do that. To my knowledge and please correct me if I am wrong but does the speakers come into dsp and then rca cables out to amp and speaker lines getting hooked into amp?
