I just got a new HU today something a little cheap to hold me over for a while till i get enoughb mondy for a better one. Now to the problem. I have three amps. I already had a HU in here so everything wuz hooked up already and all i really needed to connect wuz the ground, power, and 2 other wires i believe. I Took my dash panel out to do this and i hooked it up and everything to see if it worked before i put the panel back on. It all worked fine. So then i unhook everything from the HU and pu the panel back. Then i hook everything bakc up. The CD player comes on and works fine but now my amps wont come on anymore. I dont knwo whats wrong with it so i dont really know how to troubleshoot. So if anyone has any ideas let me know thanks.
Also, the rem may not be suppling enough power to turn on 3 amps. You may need a relay. Unhook 1 amp and see if the other two come on. If not, try feeding 1 amp with the rem. if not check to see if the rem is hot when HU is on. You can even try jumping from amp positive to amp rem erminal to see if it turns on.
Yes That B!tch works now. Thanks for the advice marc. I unhooked one of the amps and the other ones turned on and then i tried the same thing with the other ones to see if they worked to and it did. I hooked everything back up and now they all turn on agian. Now what can i do to prevent his from happining again?
