My system has gone mute well everyrhing but bass

[Hooplah]

Plugged mono blocks up and my mids and highs have completely muted unplugged everything and it still has my  speakers completely mute checked all wiring in harness and no my speakers are not blown can someone please help i have no idea what happened at all and the mids and highs are oem the sub is going but its lost all harmonics lime its just deep bass with no harmony to it at all im so lost idk what happened fuses are not blown not a noob so obvious answers I tried 

[Dragonsyph]

Only thing I can think is to check all the wires, rca’s and remote wires to see if everything is turning on.

Think I read it wrong, the speakers that aren’t  working now are powered by the decks wire harness?

[Hooplah]

Yes its all oem except the hu and the mono block obviously but the speakers are direct to the wiring harness and im guessing is just running off the hu amp or the cars oem amp i dont understand why everything shut down when i grounded the amps though everything is now disconected that isnt oem and its still mute I think my car oem amp or the hu amp may have blown but idk how to test it i thought maybe the speaker wire had grounded a d muted it all but im like 99 percent positive thats not the case

sounds like u fried your headunit or amplifier outputs

[Hooplah]

How do I know if that's what happened though just hook up oem head unit and if it plays then thats it but if not assume its the cars oem amp

[Hooplah]

And if it is the car amp can i just get a 4 channel and run different speakers and have  the problem be fixed planned on doing this in the future but if this will help I'll do it sooner then later

Let's start with what you did. It was working, then you "plugged mono blocks" . Now it's not working. Right?? Help me understand what you did.

Also. Use some punctuation, so run on sentences dont get fucked up.

Ok sorry. Yes thats exactly what happened they werent strappable so just daisy chained an ivehooked up probably 30 single monoblocks. But this is the first time ive tried hooking up 2. Everything was lit up no protect or nothing both on but no harmony. It had deep obnoxious bass but not sounding how it should no harmony just full tilt, and the mids and highs were now mute. So I unplugged it all to try from step one but nope it was still mute even after reverting back to original set up ive ran a meter on all speakersthey are all fine now my system is complete oem beside hu and i cant even get static.
