Amp Wired But No Output to Subs.

[ytmgjae]

I recently received a MB Quartz Onyx 1600 amp and I have wired it all correctly to my knowledge. Green light no protect light but I get nothing from my subs. What am I doing wrong? It says 2gauge wire is required for installation but my 4gauge wire fits in the terminal pretty good. Is it most likely the problem?

Which type of head unit do you have? Some require you to turn the sub output on. Most Kenwoods require you to change the setting before the sub output will work.

I have a JVC KWR600BTE.. Looks just like that. I do have a setting for Rear or Subwoofer. With my last amp I had it set to rear and it worked just fine.. hooked up my new amp and I get nothing.

If the power is on with the amp, then there is more then likely a signal problem. I've pinched a many rca's in day, and that will lead to a many cuss words, lol. I would retrace your signal cable, and do a continuity test with a multimeter, just to be sure.

Also check and make sure you have the rca's plugged into the input, and not the output of the amp.

Okay thank you I will try that out tomorrow and let you know what happens.. I also tried the rca to 3.5 plugged into my phone and I get output that way.. Just no Output coming from my headunit. So its either a pinched wire like you said or my Input terminals on the amp are gone. I may have pinched a wire when removing my other amp a few days ago.

Update: I was checking to make sure the RCA's were good and when I plugged them into the back of the headunit it made the subs move.. I can assume that means the amp is all wired correctly? I dont understand what is going on? Does having a factory amp make installing an aftermarket one more difficult? I had a amp before this one with no problems.

you either have a problem with a setting on the headunit or the amplifier is messed up. I am assuming the amp is your problem considering your only change was amplifiers. it might b a lot of work, but put your old amplifier back in, and see if you get bass. I have recieved a many amplifiers DOA in my day, and it's nothing but calling customer service and getting a return authorization number. you would have your new and working amp in no time!!! If it was delivered o you, then I would almost bet it has seen very cruel conditions during the delivery process//
