I installed Sony Xplods front and rear 4 months ago and decided to get an Amp, Pyle 4ch, 400 w marine amp. I had read from many who have installed amps, that this is an excellent choice. I did the install last week and have been experiencing distortion with FM radio, CD (aftermarket, which is FM modulated thru the radio) and MP3 thru the aux. I went back in and checked all the wiring, checked for polarity and checked the ground connection. The speaker wires and power wire are well separated. No luck, still experiencing distortion. The gain is set at about 2/3 max and there is not any sunstantial hiss with the volume all the way down. I have set the gain lower with no luck. Above a setting of 20 the distortion is pretty bad.
I disconnected the inputs and plugged the MP3 via the RCA's directly to the AMP. Absolutely fabulous. I think that would let me eliminate an error on the output side. Anyway, I am looking for suggestions to troubleshoot the problem. I know that with an amp, if you put garbage in, you get garbage out. The audio was not great before, but much better than it is now.
I think I remember reading somewhere that you can run a ground to each negative speaker input and that could improve the situation. Any thoughts would be appreciated!!:shrug:
