So its the factory amp thats causing all my problems then? Is it because my HU's amp is sending power to the factory amp? If thats it I'd like to just ditch my factory amp altogether. You said theres a bypass plug, where can I get one at for my car? But you still say hooking all the amp power and grounds blue & blue/white wires to power wires will get rid of the problem? I already hooked the blue/white ones from both harnesses together and it made the internal amp work. Should I take them apart and hook them to the red one then? Sorry for all the questions, but thanks for the help.

 

You bypass the factory amp if you are going to supply your own.. otherwise you want to try and utilize the factory amp. The reason you can't hear anything is because the factory amp is not being powered up... therefore no sound.

 

go to best buy buy a bypass plug for 17.99 and its plug n play... should solve your problem... yes its very common on explorers

 

Well I powered my internal amp already so it works and everything. Just have some of the feedback that changes with RPMs and s pop noise when I turn the stereo off from the speakers. So bypassing the stock amp will get rid of this?
